Repairs over Cal-Sag bridge on Harlem set to begin on Monday

  • Written by Dermot Connolly

The bridge over the Cal-Sag Channel on Harlem Avenue, connecting Palos Heights and Worth, is about to become a construction zone for the summer.

The Illinois Department of Transportation project is scheduled to begin on Monday, June 20, according to signage on Harlem. It was originally scheduled to begin on June 1, according to an IDOT press release, which said the work should be completed during the summer, weather permitting. It will include bridge repairs “necessary for safety,” as well as painting, according to an IDOT press release.

Daily lane closures are going be imposed for the duration, and traffic will be reduced to one lane, with flaggers directing traffic. However, according to IDOT, the closure times will not occur during the peak traffic volume hours between 7 and 9 a.m. and 4 and 6 p.m. weekdays.

Motorists who use the section of Harlem Avenue between 115th and 119th streets are being advised to expect delays and look for alternate routes to get where they’re going quicker. Drivers are also urged to pay close attention to flaggers and signs in the work zones, obey the posted speed limits and be on the lookout for workers and equipment.

Because Harlem Avenue is considered a state road, neither Worth or Palos Heights governments are directly involved in the IDOT project. Palos Heights police officials said that, similar to when work was done on Ridgeland Avenue, they do not anticipate that any need for special police assistance to assist with traffic control during the construction period.

“But if we’re needed, we will be there,” said Police Chief Larry Yott.
