Route description

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]
