*Year of the National Bridge Inventory data set used is the December 2017 archive, see http://www.fhwa.dot.gov/bridge/deficient.cfm
- Square Meters is Converted to Square Feet by multiplying by 10.764
**Costs used for estimates is determined by averaging the current and the previous 2 years of submitted Replacement Unit Costs of NHS Bridges.
- When cost data is not submitted for a particular year in the 3 year period, an average of the costs submitted is used.
- 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 $232/ft2
  - National Average = Average of all the costs in column '2017 Costs Collected in 2018'.
- 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 Inspection Standards (23 U.S.C.144(b)(5)).
