National Alternative Fuels Corridors

The U.S. Department of Transportation Federal Highway Administration (FHWA) designates a national network of electric vehicle (EV) charging and hydrogen, propane, and natural gas fueling infrastructure along national highway system corridors. To designate these Alternative Fuel Corridors (AFC), FHWA solicits nominations from state and local officials and works with other federal officials and industry stakeholders.

FHWA established an AFC grant program to award grants to eligible entities. During the designation and redesignation process, in consultation with the U.S. Department of Energy, FHWA will issue a report identifying charging and fueling infrastructure, best practices and guidance for predictable infrastructure deployment, analyzing standardization needs for fuel providers and purchasers, and reestablishing the goal of achieving strategic deployment of fueling infrastructure in the designated corridors.

The RFN and AFC designation for Round 7 and beyond is tied to funding eligibility under the NEVI Formula Program and the Charging and Fueling Infrastructure Discretionary Grant Program. The FHWA encourages nominations that focus on EV charging infrastructure along Interstate corridors, but nominations may also be submitted elsewhere on the National Highway System. Corridor projects along Round 7 AFCs and beyond are not eligible for the Charging and Fueling Infrastructure Discretionary Grant Program.

FHWA must update and redesignate corridors periodically. For more information, including FHWA areas of interest for corridor designations and infrastructure development, see the FHWA AFC website.
