Alternative Fuel Corridors 


With the designation of alternative fuel corridors, the Federal Highway Administration (FHWA) is establishing a national network of alternative fueling and charging infrastructure along national highway system corridors, consisting of electric vehicle (EV) charging, liquified petroleum gas (LPG), compressed natural gas (CNG), liquid natural gas (LNG), and hydrogen. The FHWA intends to support the expansion of this national network through a formal designation process that:

  • provides the opportunity for formal corridor designations on an annual basis;
  • ensures that corridor designations are selected based on criteria that promote the "build out" of a national network;
  • develops national signage and branding to help catalyze applicant and public interest;
  • encourages multi-State and regional cooperation and collaboration; and,
  • brings together a consortium of stakeholders including state agencies, utilities, alternative fuel providers, and car manufacturers to promote and advance alternative fuel corridor designations in conjunction with the Department of Energy.

FHWA has issued 5 Rounds of Requests for Nomination for AFCs and has designated portions of 119 interstates and 100 US highways and state roads. More information on FHWA’s AFC and requirements can be found here. Alternative fueling station data can be found on the Alternative Fuels Data Center’s Station Data.

MDOT Alternative Fuel Corridors: To support the deployment of low and zero emissions vehicles and reduce transportation related emissions, Maryland has nominated and received designation from the FHWA for a robust network of alternative fuel corridors (AFCs). Since the initial corridor nomination in 2016, four of the five alternative fuels types have associated Fuel Corridors in Maryland. In total, Maryland has 22 Electric Vehicle (EV) AFCs, one Compressed Natural Gas (CNG) AFC, one liquid natural gas (LNG) AFC, and 2 liquefied petroleum gas (LPG) AFCs. While there is not currently hydrogen infrastructure in the State, MDOT and ZEEVIC are exploring future infrastructure opportunities. Maps of current AFC designations in Maryland can be found below.
