Bridge Replacement
Planning Phase

The Platte River Bridge on Nodaway County Route NN was built in 1955. It was closed in July 2024 following a routine inspection that found advanced deterioration of the structure. Due to these findings and its closure, the contractor letting for this project was moved up to March 2025. The notice to proceed, the earliest a contractor may begin work on the project, is May 2025.

The current bridge will be replaced completely by a new structure. MoDOT and consultants from GBA are currently designing the new bridge.
