As part of the ongoing Your New Blue (YNB) O’Hare Branch Signal Upgrade project, which is now entering its final phase, the Chicago Transit Authority (CTA) is alerting travelers to upcoming, reoccurring weekend-only project work that will require overnight lane closures of the Kennedy Expressway (I-190) near O’Hare International Airport, and operation of a shuttle train between the O’Hare and Rosemont Blue Line stations.

As part of this $207 million, multi-year project, CTA crews are replacing a nearly four-decade-old rail signal system, which was installed when the Blue Line was extended by eight miles, from Jefferson Park to O’Hare, in the early 1980s. This project will help improve Blue Line service by allowing CTA to add trains to meet increased demand and will help improve the reliability of service.

To reduce impacts on customers and travelers, and to allow crews to perform work safely and efficiently, major project work will be scheduled for most weekends beginning the weekend of January 28-31 and continuing through late-April. In general, work will begin 10 p.m. each Friday and continue through 4 a.m. the following Monday (see service alerts  for more details). *
