U.S. DOT Announces New Round of Alternative Fuel Corridors


The U.S. Department of Transportation’s Federal Highway Administration (FHWA) on July 7 announced its sixth round of Alternative Fuel Corridors, including 250 new designations. Alternative fuel corridor designations are now found in all 50 states, the District of Columbia and Puerto Rico.

NATSO has worked with FHWA since the alternative fuel corridors program began in 2016 to ensure that the agency harnessed the knowledge and ingenuity of existing exit-based businesses for private investment for alternative fuel infrastructure.

As part of the announcement, the agency unveiled a map illustrating the progression of EV charging stations from Round 1 through Round 6 of the alternative fuel corridor designations.

Congress directed DOT to identify and establish fueling corridors to support alternative-fueling stations, including electric, hydrogen, propane and natural gas fueling infrastructure at strategic locations along major national highways in the FAST Act signed into law in December 2015. DOT was further charged with identifying the near- and long-term need for, and locations of, electric vehicle, natural gas, and propane refueling infrastructure for both passenger and commercial vehicles.

The bipartisan infrastructure law signed in 2021 requires states to implement alternative fueling stations under the National Electric Vehicle Infrastructure (NEVI) Formula Program to establish designated EV alternative fuel corridors. 

State transportation departments have until Aug. 1, 2022, to submit their plans to U.S. DOT for building out a network of EV charging stations with NEVI formula funds.  

Private sector fueling locations ensure that drivers of gasoline-powered cars do not have concerns about how many miles they can drive before refueling. A similar approach will drive demand for electric vehicle charging stations. 

Thousands of truckstops and travel centers are conveniently located less than one mile from highway exits, are highly visible and provide the amenities such as security, food, and restrooms that customers need while taking 20 to 30 minute breaks during long-distance travel. Widespread availability of DC fast chargers at these facilities will make consumers more comfortable purchasing EVs.
