With the designation of alternative fuel corridors, the U.S. Department of Transportation is establishing a national network of alternative fueling and charging infrastructure along major highways. This includes plug in electric vehicle charging, hydrogen fueling, propane (LPG) fueling, and natural gas (CNG, LNG) fueling.
These corridors allow for inter- city, regional, and national travel using clean burning fuel while also addressing range anxiety. An integrative approach was used to ease these corridors into existing transportation planning process.
Drivers are notified of accessible fueling stations with proper signage along the highway. Among the first to install proper signage were South Carolina along I-26, and Minnesota along I-94.
