Replacing the MO 45 Bridge over the Platte River


What are the Historical Impacts?

MoDOT is responsible for identifying and managing historic bridges associated with state and local projects. Federal law encourages all states to rehabilitate, reuse and preserve historic bridges. Some are made available to state and local governments, private groups and individuals.

The existing bridge is a historical bridge that is an example of multiple-span Missouri State Highway Department long-span truss design. Though not as well-preserved as it once was, it is one of only 20 remaining bridges of this subtype. It is one of three that have multiple spans, and the only one with three spans. In the late 19th and early 20th centuries, riveted Parker through trusses were built far less often than their pin-connected counterparts.

Today this bridge is considered to be eligible for the National Register of Historic Places for its engineering and for its historical integrity.

In order to mitigate the “adverse effect” the project may have on the historic bridge, MODOT will provide archival documentation to the State Historic Preservation Office for review and placement in the James C. Kirkpatrick State Information Center in Jefferson City. The documentation also will be provided to the appropriate local historical societies, and to others upon request. In addition, the bridge will be marketed and made available to others for adaptive reuse at a new location.

You may contact MoDOT for details on preserving this bridge.
