View The Historic Bridge Inventory Report For This Bridge

This bridge is structurally a traditional pin-connected Pratt through truss with six panels and an a-frame style portal bracing. Its built-up beams include v-lacing under the top chord and end post, as well as on vertical members. No builder plaque survives on the bridge. It has one unusual and beautiful detail which is a decorative cast iron flower motifs placed on the lattice railings. It is the small details like this that help ensure that each historic truss bridge is unique in some way. This small detail shows how appearance was something that was on the mind of bridge engineers and builders of the period, something no longer found on modern bridges.

This bridge presents a good restoration example in a county, which is a leader in choosing to restore its metal truss bridges. Original railings remain on the bridge, and original floorbeams are also on the bridge, both major parts of the bridge, the floorbeams structurally and the railings decoratively. The sway bracing and top chord cover plates have been replaced, as well as lateral bracing rods, however. The bridge's concrete abutments date to 1977.
