ST. LOUIS – Drivers who regularly use the ramp from southbound I-270 and eastbound I-44 to Route 366 (Watson Road) will need to determine alternate routes starting next week.
Starting Tuesday, May 26, at 9 a.m. crews will close the ramp from the two interstates to eastbound Route 366 to start work to remove and replace a bridge on the ramp.
Drivers on northbound and southbound I-270 will be able to get to eastbound I-44 during the ramp closure. Drivers on northbound I-270 will also still be able to get to eastbound Route 366. To detour around the ramp closure, drivers will need to take eastbound I-44 to Lindbergh, and take Lindbergh to Watson Road.
On Friday, May 29, at 8 p.m., crews will close the ramp from northbound I-270 to eastbound I-44, under the bridge to Route 366 so they can demolish the bridge. Drivers on northbound I-270 will still be able to get to eastbound Route 366, so they can take eastbound Route 366 to Lindbergh to get to eastbound I-44. That ramp is scheduled to reopen by 5 a.m. Monday, June 1. However, crews may still need to remove rock on either side of the ramp bridge after the demolition is complete. They will close the ramp each weeknight (June 1- June 5) between 9 p.m. and 5 a.m. to complete the rock removal.
The eastbound Route 366 (Watson Road) bridge is expected to be complete by late August 2020.
