History

State Highway 78 was authorized in 1933. The south portion of Highway 78 was still gravel in 1953. All of the route was paved by 1960. Highway 78 was extended south from the interchange with Interstate Highway 94/ US Highway 52 to Erdahl over part of CSAH 10 on June 1, 2020. In exchange, Minnesota State Highway 54 was turned back to Grant County, and is now CSAH 54.
