St. Louis County, Missouri – Night construction will close lanes on northbound I-270 at I-64, affecting overnight traffic.
According to the Missouri Department of Transportation (MoDOT), crews will close up to two northbound lanes on Interstate 270 near Interstate 64 beginning Tuesday night, March 10, as part of bridge construction work in the area.
The first lane closure is scheduled to begin at 8 p.m., with a second lane closing at 10 p.m. Both closures are expected to remain in place until 5 a.m. Wednesday morning, allowing crews to install bridge girders on the I-270 overpass above Conway Road.
MoDOT said the overnight work is designed to minimize daytime disruption but could still cause slower travel through the interchange during late evening and early morning hours.
In addition to the interstate lane closures, Conway Road will be closed underneath I-270 from 9 p.m. to 5 a.m. while crews complete the overhead work. Drivers who normally use Conway Road in this area will need to follow posted detours or use alternate nearby routes during the closure window.
Transportation officials advise motorists traveling through the I-270 and I-64 interchange corridor in west St. Louis County to plan ahead, reduce speeds near construction zones, and watch for workers and changing lane patterns overnight.
Drivers commuting late from work, evening classes, or airport routes along the I-270 corridor may want to allow extra travel time Tuesday night.
MoDOT says the schedule could shift if weather or construction conditions change. Updates will be posted through MoDOT traffic alerts and traveler information systems.
