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.
My photo of Michigan Highway 80 shows the eastern end marker at Michigan Highway 129. This is, of course, at the eastern end of Michigan Highway 80, north of Pickford. This photo was taken at the very end of July, 2022, driving from the Keweenaw to Drummond Island.
Here are some more photos of Michigan Highway 80, which I drove from end to end in August, 2022:
Michigan 80 starts out heading west from its eastern end at Michigan 129.
Michigan 80 continues west through the woods east of Kinross.
The southbound exit ramp from Interstate 75 that leads to Michigan 80 spits out traffic onto a north-south surface road (old US Highway 2), before that traffic can then turn left onto Michigan 80 eastbound. This sign assembly signifies that left turn off the surface road onto Michigan 80.
The end marker denoting the western end of Michigan 80 actually faces south, at a pair of ramps to and from southbound Interstate 75. The north-south surface highway that parallels Interstate 75 to the west holds the access point to these ramps, which lies just north of the main east-west pavement of Michigan 80.
This sign assembly faces east at the point where the southbound offramp from Interstate 75 meets the north-south surface highway just to the west. In other words, this photo looks west from the same position as the previous photo. Travelers are expected to turn left here, so they can move a bit more southerly and turn left again if they want to reach Michigan 80.
