ST. LOUIS – Drivers who use (Route 100) Manchester through Brentwood will need to determine their alternate routes now for an upcoming four-month closure.
At 8 p.m. Sunday, May 1, crews will close Route 100 just west of Hanley to replace the bridge over Black Creek. The roadway is projected to remain closed through late August.
Drivers will be able to access all business entrances between Brentwood Boulevard and Black Creek from the west during the closure. Drivers on westbound Manchester will need to turn onto Hanley before crossing Black Creek.
Crews will close one lane in each direction on Manchester over Deer Creek in Rock Hill and at Mary Avenue in Brentwood, also starting at 8 p.m. Sunday, May 1.
The signed detour for the closure includes Big Bend, the I-64 service roads and Brentwood Boulevard.
Also at 8 p.m., Sunday, May 1, crews will close the eastbound lanes of Manchester just east of Hanley Road for two months while crews make updates to the sewer system.
The bridge replacement is part of work MoDOT is doing to make significant improvements to sidewalks along Route 100 between Big Bend and Lindbergh to bring them up to Americans with Disability Act requirements and will wrap up the project with resurfacing, in summer 2023.
