Route description

Highway 70 serves as an east–west route between Mora, Brunswick, Rock Creek, and Grantsburg, WI.

The route has an interchange with Interstate 35 at the city of Rock Creek.

Highway 70 in Minnesota is a narrow roadway. The connecting route in Wisconsin, Wisconsin Highway 70, is a wide roadway with large shoulders. Highway 70 in Minnesota carries a great amount of recreational traffic to Wisconsin, as Twin Cities residents try to avoid nearby U.S. Highway 8, which is often a traffic congested route.

History

The route in Minnesota was numbered to correspond with Wisconsin Highway 70.^[2]

Minnesota 70 was authorized east of State Highway 107 (at Grasston / Braham) to the Wisconsin state line in 1933.^[2]

The portion of Highway 70 between State Highway 65 (at Brunswick) and State Highway 107 (at Grasston) was part of the original route of Highway 65 until circa 1942 when the current short-cut of Highway 65 was built.^[2]

Highway 70 in Minnesota was completely paved circa 1949.^[2]
