Michigan Highway 57 is an east-west highway spanning a significant portion of the Lower Peninsula's middle. It runs from US Route 131 north of Grand Rapids, eastward along a latitude between Saginaw and Flint. The eastern endpoint is at Michigan Highway 15 in Otisville, a town northeast of Flint. Michigan Highway 57 stays right along the same latitude for its entire length, meaning its path is very nearly due east-west. The western portion of Michigan Highway 57, beginning just outside of Cedar Springs, passes through Greenville, Michigan, the birthplace of the Meijer department store chain. Greenville is one of many small towns served by Michigan Highway 57, such as Carson City, Chesaning, Montrose, and Clio. Small towns and rural areas are the only places you'll find Michigan Highway 57, though; it doesn't enter any larger cities.
My photo of a Michigan Highway 57 marker comes from Greenville, at the junction of Michigan Highway 91 and Michigan Highway 57. The signage depicted faces north in downtown Greenville, for the usage of southbound traffic on Michigan Highway 91 who are looking for where to turn onto Michigan Highway 57. This snowy photo was taken in early March 2018, on the way home from a trip to Traverse City.
