Narrative Description:
Bridge T0104 is a 180’ long bridge with a 90’ polygonal pony truss and a 38’ wide flange girder approach span on each end. The bridge has concrete abutments with wingwalls, and concrete piers. The concrete deck has an asphalt wearing surface and two-tier channel rails.
The bridge is eligible for listing in the National Register of Historic Places under criterion C for local significance in engineering. The bridge is a good example of an early standard plan polygonal Warren pony truss. The polygonal truss design allowed for longer span lengths using less steel than earlier truss designs.
MoDOT’s Historic Preservation Section is now accepting proposals for the relocation and reuse of the bridge or its components until December 31, 2024. A proposal checklist is available MoDOT’s Free Bridges website (http://www.modot.org/freebridges/). Preservation covenants may accompany the bridge.
