Atchison County I-29 to be restored to four lanes of traffic at the Nishnabotna River

ST. JOSEPH, Mo. – Construction is wrapping up for the year on the Interstate 29 twin bridges over the Nishnabotna River in Atchison County. Crews from Phillips Hardy, Inc., working with the Missouri Department of Transportation, led the rehabilitation project of the north and southbound bridges located just south of the Iowa state line at mile marker 123. These bridges are included in Gov. Mike Parson’s $351 million Focus on Bridges program, which will repair or replace 250 bridges across the state.

Tomorrow, Wednesday, Nov. 9, 2022, crews will open the southbound bridge and restore all four lanes of traffic at this location. The process to open all lanes could take several hours while barricades are moved. Motorists should expect delays.

The northbound bridge was completed in 2021 and the southbound bridge rehabilitation began in March 2022. Traffic has been narrowed to one lane, each direction, during the rehabilitation.

One remaining piece of work, the replacement of a bridge joint on the northbound bridge, will take place in 2023. During that work, traffic will be diverted to one lane each direction on the southbound bridge. More information about the schedule of that work will be provided as it becomes available.
