Chicago Transit Authority’s Blue Signal Upgrade project enters final phase

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.
