U.S.: lowest adult base fares for light rail single-trip, by transit authority
The Memphis Area Transit Authority charged the lowest light rail fares in the United States in 2022 with 1 U.S. dollar for each single trip paid for by an adult. Most transit authorities in the lower end, such as Niagara Frontier Transportation Authority, and Maryland Transit Administration, charged an average of two dollars.
This does not represent the greatest difference when compared against the 10 authorities with the highest light rail single-trip fares for adults, with about 3 dollars for the highest reporting transit authority.
