Poplar Street Bridge Construction until October 2021

In St. Louis, the Marion Street entrance ramp to northbound I-55 and the right lane of northbound I-55 approaching the Poplar Street Bridge will close. In addition, I-64 will be reduced to a single lane approaching the bridge.

On the Illinois side, the ramp to southbound Illinois 3 and southbound Tudor Avenue in East St. Louis will close.

The ramp from northbound Piggott Avenue in East St. Louis to eastbound I-55/64, which was closed on Feb. 22, will remain closed.

IDOT urges motorists to consider alternate routes, including the Interstate 70 Stan Musial Veterans Memorial Bridge. Carpooling and using public transportation, following public health guidelines, are encouraged as well.

IDOT said the closures are necessary to replace the bridge decks on eastbound I-55/64.
