US Highway 41 Business Route (BUS US 41) was a state trunkline highway that served as a business loop off US 41 in the US state of Michigan through the City of Marquette along Washington and Front streets. Jurisdiction over the two streets was transferred to the City as part of a route swap that resulted in the decommissioning of the trunkline. It was also previously co-designated BUS M-28, mirroring the BUS US 41/BUS M-28 designations along BUS M-28 in Ishpeming and Negaunee.
