The two-year project to rehab the Interstate 435 bridge over the Missouri River, slated to begin this week, won't start for several more months.

The Missouri Department of Transportation said Tuesday the project now will not begin until late March 2020, as local department officials determined the traffic configuration needed for the rehab project would not be prudent for motorists during the winter. Crews will still do some smaller-scope rehab work during this fall, which may cause intermittent lane closures. When the project starts in earnest, traffic will be reduced to two lanes in both directions.

The bridge has about 81,500 vehicles crossing each day, MoDOT estimates, a large number of them tractor-trailers given the proximity to industrial areas.

As part of the $32 million rehab project, crews will replace the bridge deck, reinforce the structural steel and repair the substructure of the aging structure. There will also be scour repair work (replacing sediment around bridge piers that had been scooped out by swift water) in the Missouri River.

Nearby, MoDOT recently opened all lanes of I-435 at Missouri 210, where crews widened the interstate and put in a diverging diamond on M-210 under I-435.
