lasted until approximately 1936, when M-28 was moved to US 41, and the former route became CR 492. A new routing of M-28 in the Newberry area opened later that year, and a new M-28A (later Bus. M-28) existed until 1953. Another realignment in 1937 marked the transfer of M-28 out of downtown Ishpeming and Negaunee. This former routing later became Bus. M-28. In the late 1930s, a highway numbered M-178 was designated between M-28 south of Munising to M-94 in town. In 1941, the routings of M-28 and M-94 were reversed between Harvey and Munising, and M-28 supplanted the M-178 designation completely. Since then, M-28 has run along the lakeshore through Au Train. M-28 was extended along US 2 to the state line at Ironwood, and the eastern end of M-28 through Brimley was moved to a new alignment ending at US 2, in Dafter in 1942. The eastern end was moved along US 2 back to Sault Ste. Marie in 1948, though the terminus was returned to Dafter in 1950. From 1952 to 1962, M-28 crossed US 2 at Wakefield going south and stopped at the Wisconsin border, connecting with a county road. This segment of the highway (now Gogebic CR 519) was transferred back to the county in 1962. M-94 previously looped along Munising-Van Meer-Shingleton Road (now H-58 and H-15) north of M-28 between Munising and Shingleton. This routing was abandoned on November 7, 1963 in favor of the current concurrency. The last significant change to the M-28 routing occurred on March 3, 1989, when the eastern terminus was moved east to M-129. MDOT unveiled plans on March 31, 2009, to rebuild the intersection between Front Street and the eastern end of the Marquette Bypass during 2010. The previous intersection configuration dated back to the 1960s and had been labeled as "dangerous and [causing] significant traffic delays" by the designers of the replacement. A traffic study concluded in 2007 that the intersection would need either the roundabout or a traffic signal with several turning lanes to accommodate the traffic needs in the area. MDOT decided in favor of a two-lane, roundabout retaining the right-turn lanes from the previous intersection layout. These lanes will be used by right-turning traffic to bypass the circle at the center of the intersection. Construction started on the project in May. A section of the intersection was opened in July to traffic from
