Why is MoDOT undertaking this project?

Due to deteriorating conditions, a project is planned to replace following three Northwest Missouri bridges in 2023. The project will bring the bridges up to current standards and improve the driving surface. The two bridges in Atchison County are expected to remain open until construction begins, but the bridge on Gentry County YY was closed on January 5, 2023, for structural deterioration.
