Michigan Highway 80 is a short east-west route in the eastern portion of the Upper Peninsula. It exists to serve Kinross and Kincheloe, situated to the east of Interstate 75 but west of Michigan Highway 129. The western end is at Interstate 75's exit 378. Michigan Highway 80 goes easterly through Kinross Township, going through a silly little detour to the north to get around the runway at Chippewa County International Airport. Michigan Highway 80 maneuvers for seven and a half miles beyond Interstate 75 to end at Michigan Highway 129 north of Pickford.
