M-168 is one of the shortest state trunkline highways in the US state of Michigan, extending 0.953 miles (1.534 km) from a junction with M-22 in downtown Elberta to the former Ann Arbor Railroad ferry docks. It follows the south shore of Lake Betsie (formed by the Betsie River before flowing into Lake Michigan). The highway was commissioned in 1931 and served as a connection to the car ferries until 1984. Currently the road is being reconstructed by the Michigan Department of Transportation (MDOT) in preparation to transfer it to village control.
