Michigan Highway 143 is the second-shortest state highway designation in Michigan, spurring westerly from Michigan Highway 43 in East Lansing. Michigan Highway 143 runs along Michigan Avenue, tracing along part of the northern edge of Michigan State University's campus. The western end is at a border crossing between the municipality of Lansing and the municipality of East Lansing. Lansing maintains Michigan Avenue in its corporate boundaries, where as East Lansing still leaves maintenance of Michigan Avenue to the state. Thus, the piece of Michigan Highway 143 in East Lansing is allowed to continue existing. This western endpoint of Michigan Highway 143, at the municipal boundary, is about a quarter mile east of US Route 127. The eastern end is an intersection where Michigan Highway 143 merges with Michigan Highway 43, still in East Lansing, still alongside the campus of Michigan State University. The entire length of Michigan Highway 143 is just shy of a full mile.
My photo of Michigan Highway 143 shows a reassurance marker, seen by eastbound travelers approaching a turnoff to Kensington Road. This scene, like all possible scenes along Michigan Highway 143, was in East Lansing, Michigan. This photo was taken in August 2020 on the way home from the Upper Peninsula, Mackinac Island, and Traverse City.
