Construction begins this week on two Interstate 29 bridges in Atchison County.
Crews from Phillips Hardy, Inc., working with Mo-Dot, will be rehabilitating the northbound and southbound I-29 bridges over the Nishnabotna River, just south of the Iowa state line.
Beginning today crews will close both north and southbound passing lanes of I-29 to begin construction of median crossovers. During construction, intermittent lane closures are possible. In early June the crossovers will be utilized to direct traffic head-to-head in the southbound lanes of I-29 at the bridges and the replacement of the northbound bridge over the Nishnabotna River will begin.
In late October once work on the northbound bridge is complete, construction will stop for the winter season. During this time, traffic will be restored to two-lanes in each direction.
In late March 2022 the crossovers will be utilized to direct traffic head-to-head in the northbound lanes of I-29 at the bridges and the replacement of the southbound bridge over the Nishnabotna River will begin.
Contractors expect to have the southbound bridge complete in early August 2022 allowing traffic to be restored, and removal of the median crossovers will begin. During crossover removal intermittent lane closures are possible.
This project is included in Governor Mike Parson’s $351 million Focus on Bridges program, which will repair or replace 250 bridges across the state.
