M-43 (Michigan Highway) - Business Loop

Business Loop

Business M-43 (BUS M-43) was a business loop through the city of Grand Ledge. It ran east along Jefferson Street. The street curves to the southeast at a bend in the Grand River. M-100 merges in from the northeast at Bridge Street. The two highways ran concurrently south to Saginaw Highway. There, BUS M-43 ended at the intersection with M-43 while M-100 continued south.

The business loop was created when M-43 was rerouted to a new roadway southwest of downtown Grand Ledge. This roadway opened on November 14, 1959, at which time the business loop was signed along the former route in town. In 1968, BUS M-43 was decommissioned. The section not concurrent with M-100 was turned over to local control and removed from the state trunkline highway system.
