Alternative Fuel Corridor Program

FHWA’s Alternative Fuel Corridor website lists corridor designations in each State, explains the national Alternative Fuel Corridor system, and offers recordings of webinars on related topics. The site also links to FHWA’s online mapping tool, HEPGIS, where stakeholders can find interactive maps showing designated corridors by fuel type.

Alternative Fuel Toolkit


The Alternative Fuel Toolkit is joint project between FHWA, Oregon DOT, and several other State DOTs. The toolkit allows stakeholders to learn about alternative fuels, explore funding sources such as CMAQ, and take action to deploy AFVs. In addition to case studies and other resources, the website also hosts materials specific to FHWA’s alternative fuel corridor convenings, which are a series of events focused on advancing regional coordination to expand the network of nationally designated alternative fuel corridors.

National Renewable Energy Lab Corridor Planning Tools


The U.S. Department of Energy’s (DOE) National Renewable Energy Lab has developed several tools to help stakeholders expand alternative fuel corridors. The Alternative Fuels Data Center (AFDC) includes interactive maps for users to explore potential corridors by fuel type. AFDC also contains data and shapefiles for stations that meet the criteria for alternative fuel corridor designation, organized by State and fuel type. The AFDC Station Locator allows users to find the nearest alternative fueling station and includes a “corridor measurement” function to check if the driving distance between stations along Interstate Highways meets FHWA’s criteria for corridor designation.
