The Illinois Department of Transportation plans to have a lane closure Friday along westbound Interstate 55/64 near the southbound Illinois 3 exit, the agency said.
The right lane of the roadway is scheduled to be closed east of the Poplar Street Bridge from 9 a.m. to 3 p.m., IDOT said.
The left lane as well as the ramp to southbound Illinois 3 are set to be open during the work.
IDOT said workers are scheduled to repair a bridge expansion joint.
