• Abstract:
  The U.S. numbering plan was developed in the mid-1920's by the U.S. Bureau of Public Roads and the State highway agencies. The Joint Board on Interstate Highways, consisting of Federal and State highways officials, developed the numbering plan in 1925. The plan was as follows: East-west routes were assigned even numbers, with the transcontinental or major east-west routes receiving numbers ending in "0." North-south routes were assigned odd numbers, with the main routes receiving numbers ending in "1" or "5." Other routes were assigned numbers within the grid established by the main routes. In addition, branches off the main roads were assigned three-digit numbers in sequential order (for example, the first branch of U.S. 40 would be U.S. 140, the second would be U.S. 240). The Joint Board's tentative numbering plan, released in November 1925, included U.S. 12, described as follows: From Detroit, Michigan, to Saginaw, Ludington, Manitowac, Wisconsin, Stevens Point, Neillsville, Ellsworth, Minneapolis, Minnesota, Wilbur, Ortonville, Milbank, South Dakota, Selby, Lemmon, North Dakota, Miles City, Montana.
