This is an abandoned ca. 1909 pony truss with pin connections and is noted for its skew. Commisioner names are written into the concrete abutment wingwalls, and Cambria steel brands are found on the truss.

Bridge History and Significance
The pinned trusses of the single-span, full-hip Pratt pony sit upon concrete abutments and wingwalls. Its verticals are made from two pairs of laced angles riveted to pin-plates above. A pair of rectangular eyebars provide the diagonals for the second and fourth of the 15'3" panels. A round rod with turnbuckles supplies the center panel's diagonal and counter. Only the center panel is countered. Bolted to the verticals above the lower chord, I-floor-beams carry a concrete deck and 15'9" roadway. Latticed guardrails protect the trusses. The design of this bridge suggests some transition between patterns. The webbing is pinned to the top chord, but the floor-beams are bolted above the lower chord. While full-hip Pratt ponies are not common, this design decision is an understandable accommodation to two other noteworthy features in this bridge--the unusually deep skew and the span length. The span retains all its original members, including the decorated guardrails.
