History

This bridge was constructed in 1901. By the 1990s it was closed to traffic.[3] The Midland County Drain Commission demolished the bridge some time after 2006. No replacement span was constructed. At the time of demolition, it was the only surviving bedstead truss type of bridge in Michigan, a design that was used in the late 1800s.[2]

Description

The 'Ball Road-Little Salt Creek Bridge was a single-span steel pin-connected, Pratt bedstead truss bridge. The bridge spanned 40 feet and was 13 feet wide.[2] The upper chord members were constructed from two channels with cover and batten plates, the upright end posts were constructed from two channels with lacing, and the lower chord members were constructed from two angles with batten plates. Verticals were constructed from four angles with double lacing and the diagonals were constructed from two punched rectangular eyebars. The floor was supported with I-beams hung from the lower chord pins by U-bolts. Steel stringers atop the I-beams supported a timber deck. The truss was supported at each corners with steel truss legs sitting on concrete back and wingwalls. [3]
