Business M-28 (Bus. M-28) was a state trunkline highway in the Upper Peninsula of Michigan. It served as a business route running for 9.010 miles (14.500 km) through the Newberry area. The business loop followed a U-shaped routing to connect downtown Newberry with M-28 south of town. It ran west of the city of Newberry, passing through the community of Dollarville before entering downtown, turning south and ending near the county airport.
Bus. M-28 was originally a section of M-28 before the latter was realigned in the late 1930s. The highway carried the M-28A designation before it was redesignated as Bus. M-28 in 1950. The trunkline was partially turned back to local control in 1953, and the business loop designation was removed at that time. The section of the roadway in downtown Newberry has carried several different designations in addition to the original M-28.
