Trestle Bridge in 2014
The Zumbro Trestle Bridge crosses the Zumbro River and is located on a trail section that connects a trail running along Jefferson Drive to the southern portion of the Goodhue-Pioneer State Trail. The existing structure is a railroad bridge that was retrofit for trail usage. It is composed of two 50' steel plate girder spans, and seven 13'-6" timber beam spans for an approximate bridge length of 200'. The two steel plate girder spans are supported on limestone abutments and piers. The timber beam spans are supported on timber pile bent piers and a timber pile bent abutment. The existing timber deck is comprised of 8x8 timber ties running across the beams, 2x6 sleepers running longitudinally, 2x6 decking, and 8x8 curbs. An older timber handrail, and a newer chain link rail are present as well. At the SE bridge corner, a steel plaque affixed to the plate girder indicates the steel portions were fabricated by the American Bridge Co. of New York in 1903.
