Overnight ramp closures are scheduled to go into place Wednesday night at the Interstate 55/70 and Illinois 162 interchange in Troy, according to the Illinois Department of Transportation.
Lane restrictions also are planned on the bridge carrying Illinois 162 over the interstate.
Select ramps at the interchange are scheduled to be closed, weather permitting, in order for workers to seal the bridge deck, IDOT said.
The ramp closures and lane restrictions are scheduled to go in place at 10 p.m. All lanes are scheduled to be reopen by 5 a.m. Thursday, IDOT said.
Motorists will need to find alternate routes, IDOT said.
