Narrative Description:

The Platte Purchase Bridge, built in 1957, is comprised of 15 spans measuring 2,602 feet. Its symmetrical design employs five Warren trusses that range from 302 to 474 feet each.

From south to north, the Platte Purchase Bridge consists of six (6) simple span, steel plate girders forming the approach span; one (1) 302’ steel continuous cantilevered Warren deck truss; three (3) rigid-connected continuous cantilevered camelback Warren deck through trusses measuring 417, 474, and 417 feet respectively and creating the main channel span; one (1) 302’ steel continuous cantilevered Warren deck truss; and four (4) simple wide flange girder approach spans. It is supported on two steel reinforced concrete abutments, wingwalls, eight bents, and six piers.  The bridge is 25 feet 10 inches wide, curb-to-curb, and carries two lanes of one-way traffic.

 

The bridge is eligible for listing in the National Register of Historic Places as a monumental example of a steel truss, major river crossing, achieved by its distinctive cantilevered, camelback Warren through truss design. MoDOT’s Historic Preservation Section is now accepting proposals for the relocation and reuse of the bridge or its components until May 23, 2014. A proposal checklist is attached. Preservation covenants may accompany the bridge.
