Nodaway County Route NN Bridge over Platte River slated to replacement in March

A project to replace the 70-year-old Platte River Bridge on Nodaway County Route NN is scheduled for the March 2025 contractor letting through the Statewide Transportation Improvement Program.

If awarded, the contractor may begin construction as early as spring 2025. All work must be completed on or before December 1, 2025, to meet contract requirements.

The Platte River Bridge on Nodaway County Route NN was built in 1955. Following a routine inspection in August 2024, crews from the MoDOT closed the bridge due to deterioration. Motorists will need to continue using an alternate route until the project is complete and the bridge is reopened.

The contractor letting for this project was moved up to March 2025. The notice to proceed, that is the earliest a contractor may begin work on the project, is May 2025.

MoDOT and consultants from GBA Consulting Engineers are working to design the bridge replacement. This phase includes designing the bridge structure and determining traffic control.

The MoDOT Commission will consider all submitted bids at its scheduled monthly meeting in April 2025. If the lowest submitted bid meets all necessary criteria, the MHTC may award contracts at that time.
