The Duluth Transit Authority (DTA) is the transit agency that provides mass transit service — currently, only buses — in the city of Duluth, Minnesota, United States. The agency also serves nearby Proctor, Minnesota, and Superior, Wisconsin, as well as the eastern edge of Hermantown, Minnesota. The organization was formed in 1969 by the Minnesota State Legislature. In 2009, the DTA was named Transit System of the Year by the Minnesota Public Transit Association.
