Tennessee Highlights from FHWA’s
2015 National Bridge Inventory Data:

[/et_pb_text][et_pb_text admin_label=”Bullet Points” background_layout=”light” text_orientation=”left” use_border_color=”off” border_color=”#ffffff” border_style=”solid”]
  • Of the 20,106 bridges in the state, 1,026, or 5%, are classified as structurally deficient. This means one or more of the key bridge elements, such as the deck, superstructure or substructure, is considered to be in “poor” or worse condition.1
  • 2,607 bridges, or 13%, are classified as functionally obsolete. This means the bridge does not meet design standards in line with current practice.
  • Federal investment in Tennessee has supported $1.5 billion for capital improvements on 1,050 bridge projects between 2005 and 2014.2
  • Since 2004, 1,342 new bridges have been constructed in the state; 198 have undergone major reconstruction.

1 According to the Federal Highway Administration (FHWA), a bridge is classified as structurally deficient if the condition rating for the deck, superstructure, substructure or culvert and retaining walls is rated 4 or below or if the bridge receives an appraisal rating of 2 or less for structural condition or waterway adequacy. During inspections, the condition of a variety of bridge elements are rated on a scale of 0 (failed condition) to 9 (excellent condition). A rating of 4 is considered “poor” condition and the individual element displays signs of advanced section loss, deterioration, spalling or scour.
2 This data is provided by bridge owners as part of the FHWA data and is required for any bridge eligible for the Highway Bridge Replacement

Sources: All data is from the 2014 National Bridge Inventory, released by the Federal Highway Administration in January 2015. Note that specific conditions on bridge may have changed as a result of recent work. Cost estimates of bridge work provided as part of the data and have been adjusted to 2014$ for inflation and estimated project costs. Contract awards data is for state and local government awards and comes from McGraw Hill. Note that additional bridge investment may be a part of other contract awards if a smaller bridge project is included with a highway project, and that would not be accounted for in the total in this profile.
