The Anchorage Mushing District encompasses 4th Avenue between A and G Street and includes information and interpretive signage creating a walking museum that describes the history of sled dog use in Alaska.

The focal point of the Anchorage Mushing District will be a steel truss arch with the silhouette of a dog team and musher racing across the arch. This is significant as both the Iditarod Trail Sled Dog Race and the Open World Championship Sled Dog Race both begin their races on 4th Avenue.
