Laws and Regulations

The MAP-21 is the active transportation legislation providing authorizations for the Federal-aid Highway Program (FAHP); CMAQ is one of four major programs in the FAHP. The majority of MAP-21's provisions are codified in Title 23 of the United States Code, the "Highway" statute. For CMAQ, the legislation is codified at 23 USC Sec 149, while how a State's apportionment is divided among the formula programs is codified in 23 USC 104.
