Final rule.

The FHWA adopts as final an interim final rule that amends the regulation on Federal-aid highway systems to incorporate changes made by the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) and the National Highway System Designation Act of 1995 (NHS Act). The purpose of adopting the interim final rule as final is to reflect statutory changes in defining the Federal-aid highway systems, reduce regulatory requirements and simplify recordkeeping requirements imposed on States, and consolidate (in appendices to the regulation) all nonregulatory guidance material issued previously by the FHWA on this subject.
