** Costs used for estimates is determined by averaging the current and the previous 2 years of submitted Replacement Unit Costs of NHS Bridges.

  • When no cost data is submitted for the entire 3 year period, the National Average of the Costs Collected for the current year is used.
  • Blank means no cost data was submitted for the particular year.
  • Bridge construction costs may vary year to year. To minimize this variation, an average unit cost is used as it is a good measure of central tendency.
    • The use of average unit costs has historically been done for calculating the Highway Bridge Program apportionments.
  • National Average of the costs collected to replace NHS bridges is $393/ft2

FHWA initiated the collection of Replacement Unit Costs of NHS and non-NHS Bridges in 2012 as is required under MAP-21.

Collection of costs related to bridge construction is required by the National Bridge and Tunnel Inventory and Inspection Standards (23 U.S.C. 144(b)(5))
