M-50–Sandstone Creek Bridge

The M-50–Sandstone Creek Bridge, also known as th Tompkins Bridge, is a road bridge carrying M-50 over Sandstone Creek in Tompkins Township, Michigan, United States. It was listed on the National Register of Historic Places in 2000.

History
In the early 1900s, what was then Clinton Road followed the route of what is now M-50. The road was incorporated into the Michigan State Trunkline Highway System in the 1910s, with a 62 ft, pin-connected, Pratt pony truss bridge carrying the road over Sandstone Creek. In the 1920s, this bridge was deemed inadequate, and in 1927 the Michigan State Highway Department contracted with Walter Toebe and Company of Shingleton, Michigan, to construct a replacement bridge. The Wisconsin Bridge and Iron Company of Milwaukee was hired to deliver the structural steel. Modern metal guardrails were later added along the inner faces of the railings, but the bridge still carries traffic along M-50.

Description
