1974 Official Highway Map, Minnesota

Stats:

• Size: 30" x 26" unfolded, 4.5" x 7.5" folded
• Scale: 1 inch = 15.5 miles

Comments:

• The Interstate Highway construction status map has been removed in favor of a small feature on "Minnesota's Backbone". The feature explains that the state is working to upgrade Minnesota's most important "backbone" highways before they can start work to improve the trunk routes of more local importance.
