Business Spur I-375 - Detroit

The south end of Interstate 375 in Downtown Detroit connects the Chrysler Freeway with Jefferson Avenue by the Renaissance Center. The 0.168 mile transition from the freeway to Jefferson Avenue between St. Antonie and Beaubien Streets forms the unsigned Business Spur for I-375 (Bessert, 2026).

Previously the route was designated along Jefferson Avenue another block westward to M-3 at Randolph Avenue. It was originally planned to line Jefferson Avenue further to the beginning of the John C. Lodge Freeway (M-10) at the Cobo Center (Bessert, 2026).

Business Spur I-375 appeared on the Rand McNally North American Road Atlas throughout the 1980s, but it was never signed in the field.
