Drivers who use Interstate 270 near Interstate 44 in St. Louis County should plan for extra travel time or consider alternative routes this weekend due to ramp closures.

Weather permitting, crew from the Missouri Department of Transportation will close the southbound I-270 ramp to westbound I-44 (Exit 5B) Friday Sept. 22 at 8 p.m. to apply a protective epoxy overlay on the ramp. The right lane on southbound I-270 near I-44 will also be closed for the project. The ramps to eastbound I-44 will stay open.

To detour around the closure, drivers should continue southbound on I-270 to Route 30/Gravois Road (Exit 3), cross over the interstate, and then take northbound I-270 to westbound I-44.

All ramps and lanes will reopen by 5 a.m. Monday, Sept. 25.
