The Missouri Department of Transportation (MoDOT) in the US is ready to start a rehabilitation project on the I-435 Bridge over the Missouri River, which crosses Jackson and Clay Counties.

As part of the two-year project, the construction crew will replace the bridge deck, reinforce the structural steel and repair the substructure of the ageing structure.

The crew will also perform scour repair work in the Missouri River.

More than 81,500 vehicles pass over the bridge each day, most of which are tractor-trailers.

Preparatory work on the project will begin early next month, starting with the movement of equipment and concrete barriers.

Work on the bridge is anticipated to start on 23 August and is expected to continue through December 2021.

According to MoDOT, traffic will be reduced to two lanes in both directions for the duration of the project.

MoDOT said in a statement: “The I-435 Bridge rehab project will come on the heels of the completion of the I-435 and Route 210 Diverging Diamond Project, which is just north of the bridge.”

The two projects are being carried out at the same time in order to complete work in this area as quickly as possible.

Upon completion, only routine maintenance would be needed for the next 25 to 30 years.

Last week, the Missouri State Government announced that it is set to receive a $81.2m Infrastructure for Rebuilding America (INFRA) grant from the US Department of Transportation (DoT) to build a new I-70 Missouri River Bridge at Rocheport.
