Howard-bound trains will not stop at Lawrence, Argyle, Berwyn, Bryn Mawr, Thorndale, Granville, Loyola, Morse, or Jarvis stations between 10 p.m. Friday and 4 a.m. Monday, Dec. 16.
Shuttle buses will provide service toward Howard between Wilson and Howard, stopping along Broadway or Sheridan Road at the corner nearest the affected Red Line station, according to the CTA. Transfer at Wilson from Howard-bound Red Line trains to the shuttle bus.
For service to these stations, take a Howard-bound train to Howard and transfer to a 95th-bound train. For service from these stations, take a 95th-bound train to Wilson and transfer to a Howard-bound train.
Howard-bound trains will stop at their normal platform. At Sheridan, board/exit trains on the outer tracks instead of the inner tracks. At Wilson, board/exit trains on the Purple Line side of the Howard- and Linden-bound platform.
The disruption is caused by the need for track improvements in preparation for the modernization of the Red and Purple lines.
