This bridge was bypassed by a modern bridge but was fortunately left standing next to its replacing, representing a good preservation solution. The bridge remains accessible to pedestrians. It is a rare example of a multi-span Whipple truss and one of the earliest known examples of work by the Indiana Bridge Company. The bridge's spans are rather short in length (and as it logically follows, in truss height as well) compared to the average pin-connected Whipple truss. Indeed, the spans are little longer than an average pin-connected Pratt through truss. The bridge's members are also somewhat uncommonly composed, specifically the lightweight vertical members, which are simply two rolled T's with v-lacing.

Statement of Significance
This structure was built by a prolific Indiana fabricator and retains its original members. For a larger version of the same truss constructed by the same firm in the same year, see Indiana State Highway Bridge 316-90-6418. The decoratively latticed portals and the artistic, rounded portal bracing are all intact. This remains one of the earliest bridges designed by Indiana Bridge and its first two-span Whipple.
The Indiana Bridge Company of Muncie fabricated this low two-span, double-intersection Pratt (Whipple) through truss of 249'. Seated upon their original cut stone abutments and pier, each span of nine panels uses laced Ts riveted to pin plates as intermediate verticals and die-forged eyebars as diagonals (except for cylindrical rods with turnbuckles extending towards the opposite span end from the top of the central verticals). I floor beams (double U-bolted to the lower pins) support a timber deck which is 16'2" wide and provides 17' vertical clearance.
Bridge plate: "James Marsh, R.M Henderson." There are four identical plates. One on each portal.
