The CTA reminds customers that rail service between the O'Hare and Rosemont Blue Line stations will be temporarily suspended next week through Sunday, July 27 due to slow zone elimination work. Beginning at 3 a.m. Tuesday, July 8, bus shuttle service will replace rail service between the O'Hare and Rosemont stations. The bus shuttles will run 24 hours a day, the same hours of operation as the Blue Line.
Normal rail service will resume Monday, July 28.
Crews will be working to replace deteriorated rail, ties, tie plates and spikes that, when completed, will allow CTA to lift slow zone restrictions currently in effect for trains traveling between O'Hare and Rosemont.
While work is underway, Blue Line trains will make all stops to Rosemont station where customers will transfer to bus shuttles to complete their trips to O'Hare.
Customers at the Rosemont station will exit trains to transfer to CTA buses at the bus terminal en route to O'Hare. At O'Hare customers will board and alight buses at the O'Hare Bus Shuttle Center located in the airport's lower level near the flight Arrivals area (O'Hare terminals 1, 2 and 3). The bus shuttle trip between Rosemont station and O'Hare takes approximately 10 minutes. CTA personnel will be available at both locations to direct customers to awaiting buses.
Since October 2007, slow zones system-wide have been reduced from 22.5 percent to 12.8 percent.
