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. 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.
