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.
