CR-200 Bridge

Information and Findings From DHPA Historic Bridge Survey

Statement of Significance

This bridge looks a lot like an Indiana Department of Highways' Warren pony span design for the early 1930s. Its trusses are half-hip, five-paneled, and riveted. They span 60' between concrete abutments and wingwalls. The diagonals are heavier at the endposts than at center span. They are made from two pairs of angles and battens for each outer panel and a single, increasingly lighter pair towards midspan. The lower-chord members are also varied in size, each being fabricated from a pair of angles and battens at the endpost panels and from two pairs for the inner ones. The verticals consist of two pairs of angles and some battens shared with the external braces. The I floor-beams are riveted to gussets and the verticals above the lower chord and carry a timber deck with an 18'8" roadway. Narrow-channel guardrails protect the trusses. The design of this structure suggests some transition from patterns which the IDH established for its Warren pony truss spans in the 1920s. The stiffening of the outer diagonals and inner lower-chord members reflect bits of evolutionary change, although the deck is more narrow and built for slower traffic than typically found on a state highway of the 1930s.
