Michigan to Montana (M2M) I-94 Clean Fuel Corridor


The Michigan to Montana I-94 clean fuel corridor will meet the goals of the FAST Act in supporting economic security while providing for energy and environmental security. Clean Cities coalitions across this corridor are identifying gaps and assets that make I-94 an ideal corridor for delivery of alternative fuels in transportation. 

M2M Corridor Concept coalition members include:


Interstate 94 (I-94) is the northernmost east–west Interstate highway connecting the Great Lakes and Intermountain regions of the U.S. This international trade corridor originates in Port Huron, Michigan at the U.S. border with Canada at Sarnia, Ontario. I-94’s western terminus is in Billings, Montana, at a junction with I-90.

  • I-94 is the only east–west Interstate highway to form a direct connection into Canada connecting points from Seattle via I-90 to Toronto via Ontario Highway 401.
  • I-94 is the eighth longest Interstate highway’ longer than all major north–south Interstate highways (except I-75 and I-95)

Why this corridor:

While I-94 is a major Interstate highway connecting the Great Lakes and Intermountain regions of the United States there are several gaps in alternative fueling infrastructure between Michigan and Montana. The M2M project is being facilitated by Clean Cities Coalitions within the U.S. Department of Energy’s Clean Cities network along this route to give public and private fleets and individual drivers more options to fuel with cleaner alternatives such as electricity, compressed natural gas (CNG), and propane Autogas.

Potential alternative fuel demand along I-94 include:

  • Military Bases/Facilities: more than 10 in over 7 states
  • National Parks/Sites and visitors: over 19 sites in more than 6 states
  • Truck stops: over 230 across 6 states

Significant opportunities exist to fill gaps in alternative fueling across I-94 to better serve the general public; federal, state and municipal fleets, private fleets. Doing so meets the goals of the FAST Act, boosts economic activity, and increases national security across the country.
