This rule updates the regulations governing the required design standards to be utilized on Federal-aid highway program (FAHP) projects. In issuing the final rule, FHWA incorporates by reference the latest versions of design standards and standard specifications previously adopted and incorporated by reference, and removes the corresponding outdated or superseded versions of these standards and specifications. This rule also makes technical changes to the regulatory text consistent with updated Federal Register procedures.
The FHWA requests comments on a proposed revision to design standards and standard specifications that applies to new construction, reconstruction, resurfacing (except for maintenance resurfacing), restoration, and rehabilitation projects on the National Highway System (NHS). The proposed rule would incorporate by reference the latest versions of design standards and standard specifications previously adopted and incorporated by reference under 23 CFR part 625, and would remove the corresponding outdated or superseded versions of these standards and specifications. The proposed rule also would make technical changes to the regulatory text consistent with updated Federal Register procedures.
