Chicago Transit Authority Brown Line trains will be unable to enter the Loop from approximately 7:15 a.m. until 1:30 p.m. Sunday, May 9, due to structural maintenance work on the Wells Street Bridge. During this time, shuttle buses will replace rail service between the Merchandise Mart and the Clark/Lake stations. Brown Line trains will operate normally between the Kimball and Merchandise Mart stations.
Customers can use Orange,
Green and Pink line trains to travel between Clark/Lake and other Loop
stations. A shuttle train also will operate around the Loop, counterclockwise
via the Outer Loop (Brown Line) tracks.
