Downtown commuters in Chicago may have to reroute their usual trip this month.
The Chicago Transit Authority (CTA) is altering Pink and Green line service in and around the Loop amid ongoing construction on the Lake Street Bridge.
Here’s a look at which stations will be impacted and when normal service will resume.
Pink and Green line service changes in effect through Oct. 25

Both the Pink and Green line will experience service changes now through Sunday, October 25.
Here’s a breakdown of the reroutes, as outlined by the CTA:
- Green Line
- Trains will make all stops between Harlem/Lake and Clinton stations.
- Green line trains will make all stops between Ashland/63rd or Cottage Grove and the Loop.
- Service between Clinton and Clark/Lake stations will be discontinued for Green line trains. The CTA will redirect riders to free shuttle buses between the two stations.
- Pink Line
- Pink Line trains will make all stops between 54th/Cermak and Polk stations.
- Pink Line trains will then connect to the Racine Blue Line station and continue service along the Blue Line downtown.
- The CTA will redirect riders heading to/from Ashland, Morgan, Clinton stations, or West Loop to the 9/#X9 Ashland bus or other nearby northbound bus routes.

These service disruptions will impact Pink and Green line service during all hours of operation until Oct. 25. Both train lines operate daily from 4 a.m.–1 a.m. on weekdays, and 5 a.m.–1 a.m. on weekends.
Chicagoans who frequently use the Pink and Green lines should prepare for longer commute times and potential delays.
