This weekend CTA will temporarily suspend service on the O'Hare branch of the Blue Line between Western/Milwaukee and Clark/Lake on Friday, September 7 from 11 p.m. to 4 p.m. Sunday, September 9, in order to replace rail ties. Bus shuttles will operate as a substitute for rail service making stops at Western/Milwaukee, Damen, Division, Chicago, Grand, Clark/Lake, Washington, Monroe and Jackson. CTA customers are advised to allow extra travel time.
Northbound Blue Line trains will share the tracks with southbound Blue Line trains in the subway from Grand to Division on Sunday, September 9 from 4 p.m. to 1 a.m. Monday, September 10. All customers will board and exit on the southbound platform. The bus shuttle will not operate during these hours.
The work is part of an aggressive plan to eliminate slow zones. CTA is replacing deteriorated wooden rail ties with concrete rail ties which will eliminate slow zones along the tracks between Grand and Division and restore normal train speed to 55 mph.
Weeknights through mid-September, single tracks will typically be in effect from Grand to Division from 8 p.m. each night until 4 a.m. the following morning, Monday night through Friday morning. On Thursday, September 6 and Thursday, September 13 a single track will be in effect from Grand to LaSalle. Customers will board and exit trains on one side of the platform and are advised to allow extra travel time during single track hours.# # #
