M-122 was a state trunkline highway in the US state of Michigan entirely in the city of St. Ignace. The highway connected US Highway 2 (US 2) to the State Highway Ferry Dock used before the Mackinac Bridge was built. It was retired and the road returned to local control in 1957.Prior to the opening of the Mackinac Bridge, travelers wishing to venture from St. Ignace to Mackinaw City had to do so via ferry. M-122 began at US 2 (now Business Loop Interstate 75) near Straits State Park and traveled through town along Ferry Road where it ran southeasterly from the main highway. East of Hornbach Street M-122 curved around to the east near Paro Street. The highway ended at the State Ferry Docks on the southeast side of the city next to the Coast Guard station.
