Title 23 › Chapter 1— FEDERAL-AID HIGHWAYS › § 167
Creates a national highway freight program to make it easier and cheaper to move goods on major U.S. highways. The Federal Highway Administration (FHWA) must set up the program and a National Highway Freight Network. That network includes a primary highway freight system (initially 41,518 miles), critical rural freight corridors, critical urban freight corridors, and parts of the Interstate not in the primary system. Every 5 years starting 5 years after the FAST Act, FHWA will recheck and can add up to 3% more miles to the primary system using data on origins and destinations, truck traffic, key facilities and ports, energy and intermodal access, tonnage and value moved, bottlenecks, corridors, and connectivity. States and their planning groups can suggest miles for consideration. States may name roads as critical rural or critical urban freight corridors when they meet freight rules. States must use certain federal freight funds to improve freight movement on the network. FHWA figures each State’s share by how many primary-system miles the State has. If a State has 2% or more of the primary system miles, its funds are mainly for projects on the primary system and the critical rural and urban corridors; smaller States can use funds on any network part. Two years after the FAST Act, States must have a freight plan before they can obligate these funds. Up to 30% of a State’s freight money each year may go to freight intermodal or rail projects. Funds may pay for planning, construction, technology, environmental and community mitigation, truck lanes and parking, traffic and border technologies, resiliency work, and other projects that improve freight flow. FHWA may set standards for “intelligent freight transportation systems,” and freight projects under this program are treated the same as other Federal‑aid highway projects.
