The Detroit, Bay City & Western trestle near Ruby, on their main line, in 1926.  This bridge was not far from the Pere Marquette's Avoca Bridge.  The bridge was a "stick-pole" bridge and the railroad used it as a way to get into Port Huron.  It was built in the early 1920's and was gone by about 1930.  [T.
