M-107 was an east–west state trunkline highway in the Upper Peninsula of the US state of Michigan. Running for about 9.6 miles (15.4 km), it connected Lake of the Clouds and the rest of the Porcupine Mountains State Park to M-64 in Silver City. The roadway parallels the Lake Superior shoreline in Ontonagon.

The roadway was built in 1935 and named to honor the 107th Engineer Combat Battalion. The Michigan Legislature named it the "107th Engineer Memorial Road " in 2001. M-107 was transferred from the control of the Michigan Department of Transportation (MDOT) to the Ontonagon County Road Commission on June 4, 2008. This transfer decommissioned the M-107 designation and removed it from the state trunkline system.

Route description

M-107 existed to connect the Porcupine Mountains State Park with the rest of the Michigan state trunkline highway system, running parallel to the Lake Superior shoreline. It began at an intersection with M-64 in Silver City. From there, M-107 ran west into the Porcupine Mountains, crossing the Little Iron River and passing the PMSP Winter Sports Complex. The western end was at the Lake of the Clouds overlook.[4]

Lake of the Clouds

Michigan's Lake of the Clouds

w:Lake of the Clouds (Michigan)Lake of the Clouds is a lake located in Ontonagon County within the Porcupine Mountains Wilderness State Park. The lake is situated in a valley between two ridges in the Porcupine Mountains.[5] Surrounded by wilderness, the lake is a popular destination for hikers, campers, and fishermen. The lake is a prominent feature of the park, and can be viewed at the Lake of the Clouds Overlook at the west terminus of former M-107.[6]

Porcupine Mountains Wilderness State Park

The Porcupine Mountains of Michigan's Upper Peninsula

Porcupine Mountains State Park was established in 1944 to protect the last large stand of old-growth forest remaining in Michigan.[7][8] Then in 1972, Michigan passed the Wilderness and Natural areas Act. This act gave the park the new designation of the Porcupine Mountains Wilderness State Park. The facilities provided by the park include an extensive network of backcountry trails for hiking and backpacking, rustic trailside cabins, modern campgrounds, swimming and boating areas, and various interpretive programs led by park rangers. The North Country Trail passes through the park. In the winter, a ski area also operates within the park.[9] Because of the copper mining history of the park, it is a cooperating unit of Keweenaw National Historical Park.[10]


The routing of M-107 had been largely unchanged since designation. The designation was created in 1935 as a tribute to the 107th Engineer Combat Battalion. The highway was dedicated on June 13, 1954 to the battalion at a ceremony by Highway Commissioner Charles M. Ziegler. This ceremony was attended by approximately 1,200 people at a highway turnout located along the roadway 4 miles (6 km) west of Silver City. A three-short-ton (2.7 t) boulder was placed on a concrete pedestal with a bronze inscription plaque at the location of the ceremony.[2] The Michigan Legislature named M-107 the "107th Engineer Memorial Road" in 2001.[11]

On June 4, 2008, a transfer agreement was reached transferring the jurisdiction of M-107 from MDOT to the Ontonagon County Road Commission. This transfer marked the end of the M-107 designation as the roadway became a county primary road. The OCRC has named it the "107th Engineers Memorial Highway".[3]
