This is a beautiful 11 panel parker truss with riveted connections, and is seated on concrete abutments. Built in 1928 by the Pan American Bridge Company, it features a heavier design than pin connected designs of this type from decades before. V-lacing and lattice can be found all over this bridge with the exception of the diagonals and bottom chord where battens can be found linking the pairs of rolled beams together. Modern Armco railings have replaced any original railings that might have been on this bridge. Illinois mill marks can be found on the steel for the bridge. Rocker nest bearings are present on the structure. The bridge features a wooden deck with an asphalt layer on top, which may have been a replacement deck from the 1977 rehabilitation date given by the Indiana bridge inventory. A wooden deck seems out of place on a bridge built during this time period and concrete may have made up the original deck.

Statement of Significance
The only surviving Parker fabricated by this prolific Indiana firm, the structure is of rather standard pattern for its day and retains its original members including its decoratively latticed guardrails.
Fabricated by the Pan-American Bridge Company of
Newcastle, Indiana, and contracted by J. A. Crosbie, this 198'
all-riveted Parker through is seated upon concrete abutments and
wingwalls. Heavy laced channels of a single size (installed sidewise)
divide the truss into eleven panels, the top chord for each being
separately angled. Angles (growing lighter towards midspan) are riveted
together with stay plates and are installed inward from top to bottom
panel points as diagonals. Some are used as counters in the three most
central panels. Riveted to gussets and verticals above the lower chord,
girder floor beams support the asphalt-over-timber deck with its 19'7"
roadway and 14'10" of vertical clearance.
