The Illinois Department of Transportation plans to close one lane of westbound Interstate 64 between Third Street and Tudor Avenue in East St. Louis.
The right-lane closure is scheduled to go into place at 9 a.m. Monday, weather permitting, and be in place through November, IDOT said. Afterward the left lane is scheduled to be closed until the spring of 2017.
During the work, at least one lane of traffic will be closed at all times, IDOT said.
The closures are necessary to construct a new ramp connecting eastbound traffic from the Martin Luther King Bridge to westbound I-55/64 and southbound Illinois 3, IDOT said.

Delays are expected around the closure area during weekday rush hours, and IDOT is encouraging motorists to plan accordingly and use alternate routes such as the Interstate 70 Stan Musial Veterans Memorial Bridge or the Martin Luther King Bridge.
