St. Louis, MO – Drivers using westbound Interstate 44 through south St. Louis County should prepare for a full closure next weekend as MoDOT crews complete bridge repair work near the I-270 interchange.
According to the Missouri Department of Transportation, all westbound I-44 lanes will close at I-270 (mile marker 276) beginning 10 p.m. Friday, Oct. 17, through 5 a.m. Monday, Oct. 20. The shutdown also affects the ramp from northbound I-270 to westbound I-44 and the ramp from westbound Route 366 (Watson Road) to westbound I-44.
The closure marks the second weekend of bridge deck repairs on the northbound I-270 bridge over I-44. MoDOT crews will continue concrete work and maintenance during the shutdown.
Drivers are encouraged to use detours or alternate routes, as significant delays are expected on I-270, Route 366, and nearby surface streets throughout the weekend. MoDOT advises motorists to follow posted detour signs and allow extra travel time.
