Connector M-13 (Conn. M-13) is a north–south state trunkline highway running 2.41 miles (3.88 km) connecting Interstate 75/US Highway 23 (I-75/US 23) to M-13 near the community of Kawkawlin, just north of Bay City. The Michigan Department of Transportation (MDOT) internally calls the road Connector 13.[4] The freeway was once the northern end of the US 23 freeway in the area before I-75 was built to the northwest and US 23 was rerouted to follow it. When these changes were made in 1967, Conn. M-13 was designated for the freeway stub.
