County Road 492 (CR 492) is a primary county road in Marquette County. The road serves as an alternate route between Negaunee and Marquette. Several historic sites line the roadway as it runs south and parallel to the main highway, U.S. Highway 41 (US 41) through the Marquette Range in the Upper Peninsula. The path of the road runs along near tracks of the Lake Superior and Ishpeming Railroad. The western terminus of the county road is on US 41/M-28 in Negaunee and the eastern end is in Marquette next to Lake Superior.
CR 492 was previously known as the Marquette–Negaunee Road before it was made a part of the state highway system. It was originally designated as a part of M-15 as early as 1917. The superintendent of the Marquette County Road Commission, Kenneth Ingalls Sawyer, painted the first rural highway centerline on the roadway on Dead Man's Curve. The highway was later a part of M-28 before being transferred back to county control. The highway assumed its current form by 2001. The eastern section along Brookton Road in Marquette Township was redesignated as a county secondary highway when a new connection to US 41/M-28 was opened, and the designation was extended along Wright Street on the west and north sides of Marquette.
