The Illinois Department of Transportation plans to intermittently close two lanes in each direction of Interstate 270 between Interstate 255 and Sand Road in Pontoon Beach on Saturday and Sunday, the agency said.
Weather permitting, the two left lanes of eastbound and two left lanes of westbound I-270 between I-255 and Sand Road will be closed in 15 minute intervals between 7 a.m. and 8 p.m. The lane closures are necessary to allow Ameren Illinois to remove aerial electric lines, IDOT said.
Significant traffic delays are anticipated, and motorists are encouraged to use alternate routes, the agency said.
Traffic control devices will be used to assist motorists going through the work zone.
