Frequently Asked Questions
What Is The FAST Act?
Congress passed the five-year, $305 billion “Fixing America’s Surface Transportation (FAST) Act” on Dec. 3, 2015, and President Obama signed the bill the next day. The new law reauthorizes the federal highway and public transportation programs for Fiscal Years 2016-2020 and stabilizes the Highway Trust Fund during that period.
For more information, see ARTBA’s comprehensive analysis of the FAST Act.
Who Is Responsible for Building and Maintaining Roads, Transit Systems and Airports in the United States?
Almost all roads, bridges, airports and transit systems in the U.S. are owned by state and local governments or government-created agencies, which are responsible for constructing and maintaining them. Every state has a department of transportation (DOT) as do most counties and cities. You can access a state’s DOT website. The federal government helps state and local governments pay for construction and upkeep of airports, transit systems and major roads, but actually own very little of the nation’s transportation infrastructure-mainly roads in national parks and forests, Indian reservations, and military bases. The federal government, however, does own and operate the nation’s passenger rail system, Amtrak. Learn more at the U.S. DOT website.
How Does the United States Pay for Transportation Infrastructure and Improvements?
Transportation infrastructure in the U.S. is paid for largely through user-related taxes and fees that are dedicated to construction and maintenance.
The major source of funding for federal highway and transit investment is the Highway Trust Fund (HTF). The Highway Trust Fund was created by Congress in 1956 to provide money for construction of the Interstate Highway System and other federal investment in highway improvements. In 1982, Congress added a Mass Transit Account (MTA) to finance federal investment in subway and public transportation systems. Taxes paid by highway users are credited to the HTF and are used solely to pay for highway and mass transit improvements. Current revenue sources include an 18.3-cents-per-gallon federal excise tax on gasoline and gasohol, a 24.3-cents-per-gallon tax on diesel fuel, equivalent taxes on other motor fuels such as compressed natural gas, and three taxes levied on heavy trucks and truck tires. Revenues from the taxes on motor fuels are divided between the Highway Account (HA) and the Mass Transit Account by formula, while all revenues from the taxes on heavy trucks are credited to the Highway Account. In recent years, revenues have totaled in the range of $38 billion to $42 billion per year, with about $5 billion being credited to the Mass Transit Account and the rest to the Highway Account. The CBO expects HTF revenues to remain relatively stagnant for the foreseeable future.
The Federal Highway Administration and the Federal Transit Administration use HTF revenues to pay the federal share of improvements made to highways and public transportation systems. Highway Account revenues can be used to design, construct, improve and preserve Interstate Highways and most other major highways, purchase right of way, conduct environmental mitigation, and make other capital improvements, but they cannot be used for routine maintenance such as filling potholes or removing snow. Mass Transit Account revenues can be used to construct and improve subway, light rail and other mass transit systems, purchase buses and make other capital improvements, but generally not for operating expenses.
There is also a federal Airport and Airways Trust Fund, which finances airport improvements and the air traffic control system. This trust fund is financed by fees on air travelers and taxes on aviation fuels.
State governments finance highway construction and maintenance through a broad set of taxes and fees, most of which are also user-related. Every state imposes taxes on gasoline and diesel fuel, from a low of 8 cents per gallon in Alaska to over 30 cents per gallon in a handful of states. Other revenue sources include vehicle registration fees, driver license fees, sales taxes on motor vehicles, heavy truck use taxes, traffic violation fines, and similar taxes and fees.
In recent years, state governments have been expanding their use of general revenues to finance highway improvements, largely because of a political reluctance to increase gasoline tax rates, and many state governments also borrow money for highway construction by issuing bonds. A few states permit local governments to levy taxes and fees on highway users, but in most states, local highway expenditures are financed out of property tax revenues.
Another development in recent years has been the growing interest in public-private partnerships (P3), where private investors like pension funds or investment banks finance some or all of the costs of building a highway and earn a return by charging tolls.
Will the Highway Trust Fund Run Out of Money, and If so, When?
Since 2008, revenues flowing into the Highway Trust Fund (HTF) have been insufficient to fully support the level of federal highway and transit investment authorized by Congress. Prior to enactment of the FAST Act, the annual gap was nearly $15 billion. Keep in mind that Congress has not increased the federal motor fuels tax since 1993, but federal highway and public transportation spending has grown substantially over the last 22 years. It should surprise no one that holding the trust fund’s inflow of revenues constant while attempting to address the nation’s growing transportation needs would lead to an unsustainable situation. Furthermore, inflationary increases have eroded the ability of the HTF to keep up with the cost of building and repairing roads, bridges and other transportation infrastructure.
The FAST Act relies on a variety of one-time cost savings and non-transportation resources to supplement incoming trust fund revenue to support its investment levels over the next five years. These include tapping a surplus from the Federal Reserve; cutting a 6 percent annual dividend the Federal Reserve pays big banks, selling oil from the Strategic Petroleum Reserve, and other budget “gimmicks.”
While the FAST Act temporarily stabilizes federal highway and transit investment, it fails to address the Highway Trust Fund’s structural revenue deficit. As a result, the Congressional Budget Office projects a return to annual trust fund revenue shortfalls beginning in FY 2021 that will average $18 billion annually. If the run up to FAST Act approval, including numerous short-term extensions, is any guide, we will see states beginning to scale back planned projects well before the authorization expires.
Roughly $40 billion per year still flows into the HTF from the motor fuels taxes and revenue sources. The point is these existing user fees do not generate enough resources to simply maintain existing investment levels, let alone the amount needed to repair and build our nation’s critical transportation infrastructure.
How Much Is the Federal Gas Tax?
How Much Does the Federal Gas Tax Cost the Average U.S. Driver/family Each Year?
According to the Federal Highway Administration, the average motor vehicle in the United States, including cars, SUVs, minivans and pickup trucks, was driven 11,346 miles in 2013, the latest year for which data are available. The national average fuel economy for cars and light trucks was 21.6 miles per gallon, which means the average vehicle used 524 gallons of motor fuel. At a tax rate of 18.4 cents per gallon, consumers paid an average of $96.42 in federal gasoline taxes for each vehicle they owned.
According to the Bureau of Transportation Statistics, the average American household owns 1.75 vehicles, which means the average household pays $168.73 in federal motor fuel taxes, or about $3.24 per week. (Data source: Highway Statistics 2013, Table VM-1; Bureau of Transportation Statistics Transportation Statistics Annual Report, 2012)
How Much Do State Gas Taxes Cost the Average U.S. Driver/family Each Year?
What Is the Average Cost Per Mile of the Federal Gasoline Tax?
The federal excise tax rate on gasoline is 18.4 cents per gallon while the average personal motor vehicle in the United States gets 21.6 miles per gallon, which means the federal gasoline tax costs the average driver 8.5 tenths of a cent per mile.
To calculate how much federal gasoline tax you pay per mile, first determine your vehicle’s fuel economy — that is, how many miles your vehicle gets per gallon of gasoline. Then divide that number into 18.4 cents-per-gallon to calculate your tax cost per mile. For example, if your vehicle averages 15 miles-per-gallon, the federal gasoline tax costs you one-and-a-quarter penny for every mile you drive. If your vehicle gets 25 miles-per-gallon, the tax costs you only three-quarters of a penny per mile.
The U.S. Treasury Department calculates that the average cost of driving a motor vehicle is 56.5 cents per mile, when gasoline, insurance, depreciation, maintenance and repair costs are all taken into account. The federal gasoline tax thus represents 1.5 percent of the cost per mile of driving a motor vehicle in the U.S. In other words, for every dollar you spend driving your car, one and one-half cents represents the federal gas tax. (IRS Publication 463, dated Jan. 14, 2014)
How Much Does One Penny of the Federal Motor Vehicle Tax Generate for the Highway Trust Fund?
How Much Does the Federal Government Invest in Transportation Improvements Each Year?
Highways: The FAST Act provides a total of $42.4 billion for highway and bridge improvements in FY 2016 (the fiscal year from Oct. 1, 2015 through Sept. 30, 2016) and grows this amount to $46.4 billion by FY 2020… Most federal highway investment is used to upgrade and maintain the nation’s core highways, including the Interstate Highway System, and to repair and replace deficient bridges.
Mass Transit: For public transportation, the FAST Act provides a total of $11.8 billion in FY 2016—an amount that is slated to grow to 12.6 billion by FY 2020. Federal public transportation program funds are used to build and upgrade rail mass transit systems in major cities and to purchase and upgrade buses and facilities of local transit agencies.
Airports: Congress has approved legislation that will provide $3.35 billion in FY 2016 for the Airport Improvement Program (AIP), which is the federal program that provides funds to build and upgrade airport runways, taxiways and other ground facilities. AIP investment has been held at this level since FY 2012. The bill also provides funds to finance the air traffic control system and help airports pay for equipment upgrades.
Railroads: Most of the approximately $10 billion annual construction work on railroads is privately financed by the nation’s railroad companies. The federal government, however, provides an annual appropriation, of just over $1.1 billion in FY 2016, for capital improvements to Amtrak as well as an additional $289 million to help cover operating expenses.
In addition to the above amounts, Congress has provided roughly $500 million per year since FY 2009 (including FY 2016) the Transportation Investment Generating Economic Recovery (TIGER) program under which state and local governments can apply for grants that can be used for highway, transit, railway, port and related improvements. Details on all TIGER grant awards can be viewed at http://www.dot.gov/tiger.
Water: The Army Corps of Engineers is responsible for capital improvements and maintenance of the nation’s inland waterways. The regular appropriation for the Corps of Engineers in FY 2016 included $1.86 billion for construction activities.

Do We Spend More Money Each Year Building New Roads and Bridges or Repairing and Maintaining Our Existing Roads and Bridges?
The U.S. spends far more each year repairing and maintaining existing roads and bridges than building new ones, according to the Federal Highway Administration.
In 2013, the latest year for which the Federal Highway Administration has released data, the Federal highway program committed $30.1 billion for new projects improving 65,500 miles of highway and 4,887 bridges. Only $1.4 billion or 4.8 percent of this total was committed for new highway or bridge construction. An additional $3.3 billion or 10.8 percent was committed for projects that added capacity to the highway system. Almost three times as much, $13.2 billion, or 43.7 percent, was committed for improvements designed to maintain or preserve existing roads and bridges, such as road reconstruction and resurfacing, bridge replacements and bridge repairs. $2.0 billion, or 6.6 percent, was committed for traffic safety improvements, traffic management, or environmental improvements. The remaining $10.3 billion was committed for other improvements, including right of way acquisition, engineering, research and planning. (Data source: FHWA Highway Statistics 2013, Table FA-10)
State and local governments also emphasize preservation over new construction. In 2013, the latest year for which data are available, state transportation departments spent a total of $110.7 billion on highway capital improvements, including federal funds. Only $12.1 billion, or 10.9 percent, involved constructing new highways or bridges. Another $10.1 billion, or 9.1 percent, financed reconstruction projects that also added capacity to the system and widening projects. Another $25.6 billion, or 23.1 percent, was spent on preservation construction, such as roadway resurfacing and bridge repairs. In addition, state DOTs spent $17.2 billion on right of way acquisition, project engineering, safety improvements to highways, traffic management improvements, or environmental enhancement projects. States also spent close to $40 billion on routine maintenance of highways and bridges and on highway law enforcement and highway safety. (FHWA Highway Statistics 2013, Tables SF-2 and SF-12A)
How Many Miles of Roads Are There in the U.S.?
Currently, there are 4.12 million miles of road in the United States, according to the Federal Highway Administration, including Alaska and Hawaii. The core of the nation’s highway system is the 47,575 miles of Interstate Highways, which comprise just over 1 percent of highway mileage but carry one-quarter of all highway traffic. The Interstates plus another 179,650 miles of major roads comprise the National Highway System, which carries most of the highway freight and traffic in the U.S.
Most of the roads in the U.S., 2.94 million miles, are located in rural areas, with the remaining 1.18 million miles located in urban areas. Local governments are responsible for maintaining and improving 3.18 million miles of road or 77.3 percent of the total. State highway agencies are responsible for over 780 thousand miles of road, or 19.0 percent. The federal government is responsible for only 150 thousand miles of road or 3.7 percent, largely roads in national parks, military bases and Indian reservations.
Of the 4.07 million miles of road, about 2.68 million miles are paved, which includes most roads in urban areas. However, 1.39 million miles or more than one-third of all road miles in the U.S. are still unpaved gravel or dirt roads. These are largely local roads or minor collectors in rural areas of the country. (Source: Highway Statistics 2013 Table HM-20, HM-10, HM-12, HM-15, VM-202)
How Much New Road Capacity Do We Build Every Year in the U.S.?
U.S. highway capacity has been growing very slowly in recent years. Currently, the U.S. has 4.12 million center-line miles of roads, providing 8.66 million lane-miles for highway travel, according to the Federal Highway Administration.
Between 2000 and 2013, the U.S. built an average of 13,788 center-line miles of new roads per year. This, along with widening of existing roads, added 31,217 lane-miles per year. This means the capacity of the highway system grew only 5.3 percent during those 13 years. At the same time, the U.S. population grew 12 percent and the number of licensed drivers grew by 11 percent, while the number of vehicle miles traveled on the nation’s highways grew 8.8 percent.
Furthermore, more than 64 percent of the new road capacity added during that time represented local roads to develop new residential neighborhoods. Only 18 percent represented new capacity on the Interstate Highways and other major roads that carry most highway traffic. It’s no wonder congestion increases every year. (Source: Highway Statistics 2000 and 2013, VM202 for VMT; Chart DL-1C for population and drivers; Table HM-220 and HM-260 for miles and lane-miles of road)
Are We “Paving Over America”? How Much Land Is Used for Roads in the U.S.?
Based on data from the Federal Highway Administration, roads take up much less than 1 percent of the land area of the U.S.
The total land area of the contiguous 48 states is 2,959,067 square miles. (This excludes Alaska and Hawaii. Alaska has 17 percent of the land area of the U.S., but few roads. Adding Alaska would significantly reduce the percentage of land covered by roads.)
There are currently 8,614,790 lane miles of road in the lower 48 states. The average width of a highway lane is 11 feet. This means roads cover 17,947 square miles of land, or just six-tenths of 1 percent of the total land area of the contiguous 48 states. Even if shoulders, driveways and parking lots were added, the total would still be less than 1 percent of the nation’s land area.
Between 2000 and 2013, the U.S. built an average of 33,217 lane miles of highway per year. This added 69.2 square miles per year to the amount of land covered by roads. At this rate of highway construction, it would take 168 years to increase the U.S. land mass covered by roads to even 1 percent. (Source: Highway Statistics 2013, Tables HM-220 and HM-60 )
Other Than Highways, What Is the Composition of the U.S. Transportation Infrastructure?
The United States has an extensive transportation network. In addition to 4.12 million miles of roads, transportation infrastructure consists of:
- 608,445 bridges
- 5,145 public-use airports, 13,863 private airports that serve recreational and business air travel and 286 military airports.
- 138,565 miles of railroad track that carries much of the nation’s heavy freight and agricultural output. This includes track operated by the nation’s Class 1 freight railroads, regional freight railroads and local freight railroads. Amtrak operates 21,225 miles of passenger rail service in the U.S., much of it over track owned by the freight railroads.
- Over 271,000 route-miles of scheduled bus service plus 12,413 miles of fixed rail transit including trolley buses, commuter rail, subways and light rail systems. The fixed-rail transit systems serve 3,216 stations where passengers can board or exit trains.
- 15,322 waterway facilities on 29,620 miles of navigable channels in the United States. (Source: Bureau of Transportation Statistics National Transportation Statistics, National Transit Database, Federal Highway Statistics 2013, ARTBA 2015 Economic Profile)
What Is the Condition of the Nation’s Highway Network?
There are two measures that are used to assess the condition of the nation’s highways. One focuses on physical conditions, i.e., whether the roadways and bridges are in good repair. The other focuses on performance, i.e., whether the system is providing adequate transportation services to meet the nation’s needs.
Unfortunately, U.S. highways do poorly under either measure.
Physical Conditions: The Federal Highway Administration tracks the state of repair on 1,006,257 miles of major highways that are eligible for federal aid. In 2013, the latest data available, the FHWA found that 161,971 miles, or 16.1 percent, were in poor or mediocre condition and needed repaving or even more substantive repairs.
Highways in rural areas are in somewhat better condition, with 11.0 percent of rural miles in poor or mediocre condition, than those in urban areas, where 26.3 percent of miles need repairs. Urban highways carry more traffic and thus get more wear and tear. The nation’s Interstate Highways are in relatively good condition, with only 2.0 percent of rural miles and 5.3 percent of urban miles in poor or mediocre repair. Other highways, however, are in much worse shape, particularly in urban areas where more than one third of all arterial and collector miles are in poor or mediocre condition.
There is no information on the condition of the 3.1 million miles of local roads and rural minor connectors that are not eligible for federal aid. But if the same 16.1 percent are in poor or mediocre condition, then 500,582 miles of these roads would also be in need of repair. (Source: 2013 Highway Statistics, Tables HM-63 and HM-64).
Bridges: The Federal Highway Administration’s 2015 National Bridge Inventory shows that 141,651, or 23.2 percent, of the nation’s 609,539 bridges (excluding Puerto Rico) are either structurally deficient or functionally obsolete. This includes 58,495 structurally deficient bridges (9.6 percent), which are safe to use but need significant maintenance or repair to remain in service, and 83,156 functionally obsolete bridges (13.6 percent) which may be in good repair but fail to meet current design standards, such as lane width, shoulder width or overhead clearance and thus need to be upgraded when they are replaced. (Source: National Bridge Inventory 2015 data)
In recent years, state and local highway agencies have been investing heavily in bridge maintenance and repairs. As a result, bridge conditions have been improving. Between 1998 and 2015, the number of deficient bridges fell from 29.5 percent to 23.2 percent. The improvement was concentrated in structurally deficient bridges, which declined from 16.0 percent of all bridges to 9.6 percent. The number of functionally obsolete bridges stayed about the same, at 13.6 percent.
Performance: The performance of the nation’s highway system is measured by the amount of congestion and delay incurred by highway users. The latest information is from the Texas Transportation Institute’s 2015 “Urban Mobility Scorecard,” which provided data on highway performance through 2014.
According to the report, congestion caused Americans to spend an extra 6.9 billion hours in their cars and trucks in 2014 and to purchase an extra 3.1 billion gallons of fuel for a congestion cost of $160 billion. Of that total, $28 billion represented the impact of congestion on the U.S. trucking industry, which raised the price paid by American households for many goods and services.
For the average U.S. motorist, congestion during peak periods added 42 hours to their driving time in 2014 and caused each one to waste 19 gallons of gasoline, for an annual cost of $960 per motorist.
All of the measures of congestion and delay have been getting progressively worse since the Texas Transportation Institute issued its first report in 1982. Furthermore, the problem of congestion has been spreading to smaller and smaller cities. In 1982, only one city, Los Angeles, registered a delay of more than 40 hours per motorist. In 2014, the average delay for the 101 largest cities in the U.S. was 52 hours per motorist, with Washington, D.C., motorists experiencing 82 hours of delay, Los Angeles 80 hours and San Francisco 78 hours.
Which State’s Roads and Bridges Are in the Best Condition, and Which Are in the Worst Condition?
According to 2013 data from the Federal Highway Administration—the latest available— Connecticut has the worst roads in the country, with 42.1 percent of all federal-aid highway miles in poor or mediocre condition. Not far behind: Hawaii with 41.8 percent and Rhode Island with 37.4 percent. Other states with more than 30 percent of federal-aid road miles in poor or mediocre condition are New Jersey (36.3 percent), California (35.3 percent), Michigan (33.7 percent), and Washington (32.0 percent).
The state reporting the best road conditions is Nevada, with only 2.2 percent of federal-aid highway miles in poor or mediocre condition, followed by Nebraska with 2.5 percent. Other states with roads in relatively good condition include Iowa (3.2 percent in poor or mediocre condition), Florida (4.8 percent), Tennessee (5.2 percent), Arizona (6.4 percent), Minnesota (6.6 percent) and South Dakota (6.9 percent).
Hawaii and Alaska have the worst Interstate Highways, with 31.5 percent and 10.5 percent of miles respectively in poor or mediocre condition. The states with Interstate Highways in the best condition in 2013 were Kansas and Rhode Island, each reporting no miles in poor or mediocre condition. (Source: 2013 Highway Statistics, Tables HM-63 and HM-64)
According to the 2015 National Bridge Inventory, the state with the worst bridge conditions is Rhode Island, where 56.0 percent are designated either structurally deficient or functionally obsolete. Second is Massachusetts with 52.1 percent, followed by Hawaii with 43.3 percent and Pennsylvania with 40.0 percent.
The state with the best bridges is Minnesota, where only 8.9 percent of bridges are designated as structurally deficient or functionally obsolete. Other states with good bridge conditions include Arizona, Nevada and Wisconsin, which all have less than 15 percent of their bridges designated as structurally deficient or functionally obsolete.
How Much Will It Cost to Improve the Condition and Performance of Our Nation’s Surface Transportation Systems?
According to data from the U.S. Department of Transportation’s 2013 “Report to Congress on the Conditions and Performance of the Nation’s Highways, Bridges and Transit,”—the most recent report— all levels of government should be investing $95.6 billion in highway improvements during 2014 just to maintain current physical and performance conditions on the nation’s highways and bridges. This would grow to $109 billion by 2020 if highway construction costs grow at the same rate as the overall inflation rate. The cost to improve our nation’s highways by making all investments with a positive benefit-cost ratio would be $161.7 billion in FY 2014, growing to $184.2 billion by FY 2020.
Traditionally, the federal highway program has financed fewer than 45 percent of all highway improvements while state and local governments have financed the rest. This means Congress should be providing $49.4 billion for the federal highway program in FY 2014 to just to maintain current highway conditions plus administrative and research costs. Actual funding for the federal highway program in FY 2014 under MAP-21 will be $40.9 billion, or about $9 billion less than the federal share needed to maintain current conditions. The federal share of the cost to improve highways would be $83.6 billion in FY 2014, or double the current investment.
The current level of federal investment in the transit formula programs, just under $8.5 billion in FY 2014, comes much closer to the $8.8 billion federal share of investment needed to bring current transit systems and equipment to a state of good repair according to the 2013 Conditions and Performance Report. To achieve a state of good repair and accommodate the projected increase in transit ridership would require a FY 2014 federal investment of $10.48 billion. The report, however, does not try to estimate needed investment in new transit systems, for which the federal government will provide $1.9 billion in FY 2014.
In addition to the regular annual investment in highways and transit, the American Recovery & Reinvestment Act of 2009 provided a one-time injection of $27.5 billion of federal funds for quick-start highway improvements to help stimulate the economy and $8.4 billion for transit. These investments helped address the shortfall in highway and transit investment but much more is still needed. (Source: ARTBA analysis of 2013 Conditions and Performance Report).
What States Have the Most Road Mileage? The Most Bridges? Most Airports?
According to Federal Highway Administration data, the state with the most road mileage is Texas, with 313,228 miles. California is second with 174,989 miles.
Texas also has more bridges than any other state, a total of 53,209, followed by Ohio with 27,104.
The state with the most airports is Texas with 1,426. Alaska comes in second with 559 airports.

Who Designs and Builds Roads and Bridges?
What Kinds of Jobs Are There in Transportation Construction? How Much Do They Pay? What Education and Skills Are Needed?
There are a broad range of career opportunities in transportation construction, providing relatively well-paid jobs for workers of virtually all educational levels and skills. The main employers are state and local departments of transportation, private engineering and design firms, and private construction companies. Each offers a different mix of career opportunities. Job opportunities at state and local departments of transportation and private engineering firms include:
- Civil engineers, who design projects to build or improve transportation infrastructure;
- Transportation planners, who determine infrastructure needs;
- Contract managers, who draw up and oversee contracts with private engineering companies and construction firms to design and build construction projects;
- Inspectors, who monitor the progress and quality of construction work to assure contract provisions are met;
- Auditors and finance officers, who pay bills, collect receivables, and assure accuracy of financial transactions;
- IT personnel, since most operations and records are now computerized;
- Construction managers, who manage large construction projects on behalf of state or local departments of transportation; and
- Office and clerical workers.
Most of these occupations require a college degree and some require advanced training. Salaries and benefits match those of similar professions. The career opportunities provided by construction companies focus more heavily on construction occupations, although managerial and professional jobs are also important. In addition to jobs similar to those described above, the jobs at construction companies include:
- Project manager, who manages all aspects of a construction project;
- Estimator, who can work from engineering plans to determine how much it will cost to build a project and thus the amount the construction company should bid;
- Safety and environmental compliance managers;
- Purchasing agent, who is responsible for purchasing needed materials and equipment;
- Heavy equipment operators and truck drivers;
- Skilled craftsmen, such as carpenters, electricians and mechanics;
- Communications and marketing personnel; and
- Laborers, who do a variety of jobs that may not require special skills.
Educational requirements vary by occupation, with most requiring at least a high school diploma or equivalent. Skills can be developed in training courses and on the job. Salaries are very competitive with similar jobs in manufacturing and well above those in many service industries. Each year, ARTBA conducts a survey of wages and salaries paid by construction companies for most jobs. The following table shows the national average for many construction jobs in 2008, although local wages and salaries can vary significantly.
What Materials and Equipment Are Used to Build Roads and Bridges?
There are hundreds of industries that provide materials and services for the construction of the nation’s highways, bridges, airports, ports and transit infrastructure systems. The principal materials used in highway and bridge construction include asphalt, aggregates, concrete, cement and steel. Highway and bridge construction is an important market for many of these suppliers. The U.S. Bureau of Economic Analysis (http://www.bea.gov/) provides information on the purchases and inputs used by industries in the United States. According to their data, output in the following industries is dependent on the highway and bridge construction.
How Much Does It Cost to Build a Mile of Road?
There is no single answer to this question. Construction costs per mile of road depend on location, terrain, type of construction, number of lanes, lane width, durability, number of bridges, etc. It costs more to build a new road than to rehabilitate a road or add lanes. Roads cost more to build in urban areas than in rural areas. Roads in mountainous terrain are more expensive to build than roads on flat land.
Nonetheless, some states have developed cost models to guide planning for their highway construction programs. These models give a ballpark figure for various kinds of highway improvements. The following are some examples:
- Construct a new 2-lane undivided road – about $2 million to $3 million per mile in rural areas, about $3 million to $5 million in urban areas.
- Construct a new 4-lane highway — $4 million to $6 million per mile in rural and suburban areas, $8 million to $10 million per mile in urban areas.
- Construct a new 6-lane Interstate highway – about $7 million per mile in rural areas, $11 million or more per mile in urban areas.
- Mill and resurface a 4-lane road – about $1.25 million per mile.
- Expand an Interstate Highway from four lanes to six lanes – about $4 million per mile.
How Safe Are Our Nation’s Highways?
In 2013, 32,719 people were killed on the nation’s roads, according to the National Highway Traffic Safety Administration (NHTSA). Another three million were injured. Motor vehicle accidents are the leading cause of death of Americans between the ages of 1 and 24 years old. In 2013, motor vehicle accidents accounted for more than one out of every five deaths among this age group. (Source: Centers for Disease Control, National Center for Health Statistics, National Vital Statistics Report, Volume 64, Number 2, Tables 3 and 10, National Highway Traffic Safety Administration Fatality Analysis Reporting System).
Poor road conditions contribute to more than one-third of all highway fatalities, according to the NHTSA safety data. Better alignments, wider lanes, median barriers, improved signage and signals, turn lanes, crash cushions, wider shoulders, utility pole relocation and other highway improvements could save thousands of lives each year. Almost three-quarters of all fatal accidents occur on two-lane roads. (NHTSA, Traffic Safety Facts, 2013) The Interstate Highways, despite high speeds, are the safest roads, with 0.55 fatalities per 100 million miles of travel. Wide lanes, gentle curves, long lines of sight, wide shoulders, barrier separated traffic and limited access points all contribute to the safety record. The worst are rural major collectors with a record of 2.29 fatalities per 100 million miles of travel (Highway Statistics 2013, Tables VM-202, FI-30 and FI-210).
Construction of the Interstate Highways has saved thousands of lives over the years. If all highway traffic were to occur today on the same kinds of roads as we had in the 1950’s, the number of highway fatalities each year would exceed 159,000. NHTSA reports that highway crashes cost Americans $242 billion annually, including the cost of medical bills, lost wages, legal fees, auto repairs and delays. This is almost 2 percent of the nation’s total output of goods and services or Gross Domestic Product. The average cost per household is close to $1,950 per year. According to NHTSA, public revenues paid for 7 percent of crash costs, adding $156 annually to the tax bill of every household in the U.S.
How Important Is the U.S. Transportation Infrastructure Network to the U.S. Economy?
A safe and efficient transportation system is one of the fundamental requirements of a modern economy. Virtually every business and industry depends on the transportation system to obtain needed materials and labor and to get goods and services to customers. Every household depends in some measure on the transportation system for access to work, shopping, medical care, church, family and entertainment. Millions of workers depend directly on the transportation system for jobs – auto workers, bus and truck drivers, airline workers, auto mechanics and gas station attendants, and hotel employees, among others.
Jobs: Building and maintaining the nation’s transportation infrastructure is itself a major source of jobs in the U.S. Every $1 billion invested in highways supports 27,823 jobs, according to the Federal Highway Administration, including 9,537 on-site construction jobs, 4,324 jobs in supplier industries and 13,962 jobs throughout the rest of the economy. Investment in other modes would support a similar number of jobs.
In 2014, $126 billion worth of construction work was performed on transportation projects, including highways, bridges, subways, light rail systems, freight rail, airports and water ports. This investment supported over 3.5 million jobs in the U.S., including 1.2 million construction jobs. Maintenance and administration of the nation’s highways and other transportation infrastructure supported additional jobs.
Freight: In 2015, according to the Federal Highway Administration, more than $19.7 trillion dollars of freight was shipped in the U.S. including $15.3 trillion of domestic shipments and $4.4 trillion of exports and imports. Seventy-two percent of the total, or $14.3 trillion, was shipped by truck on the nation’s highways. Another 12.1 percent, or $2.4 trillion, involved multiple modes including trucks, which means trucks were involved in 85 percent of all freight shipped in the U.S. in 2015. Rail, air, water and pipelines accounted for the remaining 15 percent of freight shipments. (Source: FHWA Freight Analysis Framework)
The Federal Highway Administration estimates that the volume of freight shipments will almost double between 2015 and 2040 in constant dollars, with 66 percent of that carried by truck and 21 percent by intermodal combinations that include trucks. The growth will put enormous pressure on every element of the nation’s transportation infrastructure. (FHWA Freight Analysis Framework)
Benefits to businesses: Businesses have always depended on the nation’s transportation system to connect to suppliers and customers, but during the past 25 years improvements in transportation have also been a major source of productivity increases and reduced costs for many U.S. businesses. Manufacturers and retailers today use the just-in-time delivery system to assure materials are available when needed in the manufacturing and production process and finished goods arrive at retail stores and customers’ docks in a timely manner. This has greatly reduced the need and expense of warehousing inventory, freeing up scarce capital to invest in, and make improvements to, other business activities like technology, product quality and marketing.
Just-in-time logistics, however, require a dependable transportation system, which is threatened by the ever-growing problem of congestion on our highways, rail, airports and water ports. Congestion makes transportation slower, more costly and unreliable. Adapting to congestion requires scheduling more time for trips, which raises labor costs, or holding more inventory which ties up capital. When that happens, the economy becomes less productive, costs increase and living standards decline.
Personal mobility: Americans are among the most mobile people on earth. In 2013, the latest year for which data are available, Americans traveled a total of 4.99 trillion miles by all transportation modes, or an average of 15,791 miles per person. Most of the travel, 3.99 trillion miles, or 79.8 percent, of the total, was by automobile, truck or motorcycle, an average of 12,606 miles per person.
Air travel accounted for 590 billion miles or 11.8 percent of the total, while intercity buses and public transportation, including bus and rail, accounted for 417 billion miles of travel, or 8.4 percent of the total.
Virtually every trip has an economic purpose or impact on the economy. Most obvious is the daily commute to and from work for the nation’s 139 million workers. But every trip to the grocery store or shopping center has an economic impact, as do trips to restaurants, to the movies, to vacation spots, to school, even to church where the weekly offering helps maintain the building and clergy. And many trips are essential to our quality of life, including visits to family and friends, a night out after a hard day’s work, a drive in the country or an emergency trip to the hospital.
Defense and security: The U.S. transportation infrastructure is critical to our national defense and homeland security. More than 60,000 miles of roads have been designated part of the Strategic Highway Network, including the entire Interstate Highway System, because of their important role in transporting military equipment and personnel. Roads also comprise the primary evacuation routes in the event of an attack by a foreign enemy such as that on the World Trade Center in 2001, or a natural disaster like Hurricane Katrina in 2005 and Hurricane Sandy in 2012. These disasters taught the need for both adequate capacity and redundancy in the nation’s transportation system.
Does the Public Have Any Say About the Location and Building of Roads, Bridges, Transit Systems and Airports?
Are There Any Laws or Regulations Planners and Builders Must Follow to Help Make Sure Transportation Projects Are Environmentally Sensitive?
How Much Time Is Taken to Ensure Transportation Construction Projects Are Meeting All of Their Environmental Responsibilities and Requirements?
How Does Road Construction Today Impact the Nation’s Wetlands?
Does the Transportation Construction Industry Recycle Materials to Lessen Environmental Impacts?
Does Building New Roads Cause More Driving, More Traffic, and, Therefore, More Air Pollution?
No! Just as building new schools does not “cause” more students or studying, building roads does not “cause” more drivers or traffic. Both schools and roads, like other public infrastructure and housing, are built to accommodate an ever growing U.S. population and economy. New roads do provide new access opportunities for citizens and businesses-to jobs and employees, health care, shopping, recreation and family. Whether or not they use a particular road, however, depends on whether they think it provides them with a more efficient (less time spent), less expensive (less money spent), or safer route than their other transportation alternatives. And according to both the Federal Highway Administration and the U.S. Environmental Protection Agency, despite gains in gross domestic product, population and vehicle miles traveled, the nation’s air quality has improved. Specifically, between 1970 and 2002, the transportation sector has helped reduce volatile organic compounds (VOCs) by 73 percent, nitrous oxides (NOx) by 41 percent, particulate matter (PM) by 50 percent, and carbon monoxide (CO) by 62 percent. NOx and VOCs are precursors to ozone and associated with greenhouse gasses and climate change. As levels of VOCs and NOx continue to decrease, so will ozone and greenhouse gases.
