NBIS sets the national standards for the proper safety inspection and evaluation of all highway bridges in accordance with 23 U.S.C. 151. This took effect January 13, 2005.
Why were the FHWA bridge inspection program regulations developed and what is the history of the program?
This was result of the Federal-Aid Highway Act of 1968 that required the Secretary of Transportation to establish national bridge inspection standards (NBIS).
The purpose of NBIS is to locate and evaluate existing bridge deficiencies & ensure safety of the public.
