C-66 is a county-designated highway in the US state of Michigan running about across the northern tip of the Lower Peninsula. The roadway starts in the unincorporated community of Cross Village in Emmet County at an intersection with M-119 and C-77. It follows Levering Road through rural areas to an interchange with Interstate 75 (I-75) west of Cheboygan. The eastern terminus is at an intersection with US Highway 23 (US 23) and M-27 in downtown Cheboygan. The first roadways along what is now C-66 were in place by the early 20th century. Segments were paved by 1936, although some reverted to a gravel surface during World War II. The full roadway was paved by the mid-1950s, and the C-66 moniker was designated on the roadway in the early 1970s.
