Location: Dead River Railroad Trestle, Negaunee, MI - (LSI)

The LS&I bridge over the Dead River was built in 1916, replacing a timber trestle built in 1896. The old trestle was made of timber and increasing weight of locomotive and ore cars required a safer bridge. The 1916 structure is 565' long, stands 104' above the base of the center pier, and consists of nine steel girder spans and one reinforced concrete girder span resting on eight steel piers, two concrete piers, and concrete abutments. The spans vary in length from 30' to 116'. It is still used today. [UPM]
