Miller Trunk Corridor

The Highway 53 or Miller Trunk Corridor refers to a large agglomeration of retail development in Duluth, Minnesota on and around U.S. Highway 53, and by extension, State Highway 194 (Central Entrance), and parts of the Arrowhead, Haines, and Maple Grove Roads. The Miller Hill Mall is the most visible of the corridor's anchors, although not the first.

Most chain stores and restaurants present in Duluth are found in the corridor, although numerous local businesses are present as well.
