Road Commission were negotiating with MDOT to transfer the jurisdiction of Marquette County Road 480 to the state. Several routing options have been discussed, though all would make CR 480 a part of M-28. Cost was the primary reason given behind rerouting M-28 along CR 480. "The road commission receives about $50,000 a year in state gas tax money but spends about $100,000 to maintain CR 480 because of the type and volume of traffic it receives." Handing CR 480 over to the state would shift the maintenance costs to the state, as well. MDOT has indicated that it has not requested jurisdiction, but rather if it assumed control of the route, the community would need to support a through-route. Several proposals have arisen, including creating a "spur" from US 41/M-28 through the east end of Ishpeming to meet CR 480 west of Negaunee. This spur would pass through recently reopened former mining "caving grounds", and to the south of the Mather A & B Mine complex. According to Gerry Corkin, Marquette County Board Chairman, "the land that was purchased by Ishpeming and Negaunee, the mining company land, this has the potential to help in the development of that if this is compatible. I think both cities will be interested in taking a look at what the land uses are and where this [spur] would push through." The spur proposal would open land to development between the downtown areas of the two cities. If jurisdiction is transferred, and M-28 is routed over CR 480 as proposed, M-28 would leave the concurrency with US 41 near Teal Lake in Negaunee, and cross the caving grounds west of downtown to connect to Rail Street. Rail Street would serve as the connector to CR 480, which ends at the intersection of Rail and Ann streets and Healey Avenue. Proposals indicate two routing options for the east end of CR 480. One would route M-28 back along US 41 from Beaver Grove north of the CR 480 eastern terminus to the existing M-28 in Harvey. A second would route it along CR 551/Cherry Creek Road from CR 480 to M-28 in Harvey. Business loops There have been three business loops for M-28: Ishpeming–Negaunee, Marquette and Newberry. Only the business loop serving Ishpeming and Negaunee is still a state-maintained trunkline. US 41/M-28 was relocated to bypass the two cities' downtowns in 1937. The highway through
