Repair work on a southbound U.S. 63 bridge will cause the passing lane to be closed May 29 to mid-June, according to a Missouri Department of Transportation news release.
The project is scheduled to be completed in early July.
A portion of the right-side driving lane is currently closed south of Discovery Parkway near Columbia, but the closure will switch to the left-side passing lane during the overnight hours May 29 as work begins on the underside of the bridge over Bonne Femme Creek. This 12-foot lane will be open through the work zone until mid-June.
Rush-hour traffic for southbound motorists is expected to be regularly delayed 30 minutes or more and could reach as much as two hours.
A new acceleration lane will be constructed to increase safety while accessing southbound U.S. 63 from the outer road.
The southbound turn north of the bridge will remain open. Tom Bass Road (U.S. 63 South Outer Road) will be open, but access to the road from southbound U.S. 63 will be closed during repairs.
MoDOT encourages drivers to use both lanes of traffic until they reach the point where the road is closed and take turns safely merging into the open lane.
