Drivers on downtown St. Louis interstates should expect overnight closures along I-55 and westbound I-44 during the next five days as crews place girders and set panels for a new ramp, according to the Missouri Department of Transportation.
Crews plan to work on connecting the new ramp from the westbound Poplar Street Bridge to southbound I-55, MoDOT said.
MoDOT’s planned closures:
▪ Thursday: One left lane is set to be closed on northbound I-55. Overnight, northbound I-55/eastbound I-44 will be closed from 8 p.m. to 5 a.m. from 7th Street and Park Avenue to Washington Avenue. The ramp from eastbound I-44 is expected to remain closed until Thursday as well.
