South Carolina

SC was the first state in the USA to make the decision and execute developing corridor identification (not wayfinding) signage and place them across the state. they produced and shared publicly many documents that explain their process, approvals, costs, communications with SCDOT… even an Installation Checklist.

All SC documents can be found on their Alternative Fuel Corridors page
Photos of their signs can be found in this Flickr album – the first three signs are example of the ones that can currently be found across SC!

When the Council started in 2019, it was the “Southeastern Corridor Council”. In 2021, the Council started working to include other states and expand the ability to drive improved communications to other regions of the U.S. This expansion work continues and other state Clean Cities coalitions and state DOTs are still joining the effort today. The name was changed to the “National Alternative Fuel Corridor Council” in early 2022.
