Districts Impacted
Washing the eastbound and westbound bridges on U.S. Route 54 over the Missouri River in Cole and Callaway counties is a necessary part of maintaining the structures. The cleaning and flushing are done to remove dirt and debris to allow proper drainage and drying of the deck. Dirt and debris hold moisture and chlorides that cause deterioration.
PROJECT PROGRESS
The Missouri Department of Transportation has planned bridge maintenance to help prevent deterioration. This project includes a thorough washing of the bridge deck, gutters, drains, beam caps and bearing areas, joints, and exposed steel below the deck to remove debris and associated chlorides.
The Missouri Highways and Transportation Commission awarded a $387,388 contract to AAD Contracting, Inc to complete this work.
Construction crews began work on March 8, 2024. One or two lanes of the Missouri River Bridge was closed from 7 p.m. to 6 a.m. throughout this routine maintenance.
This routine bridge maintenance is complete.
