CTA Loop Stations Shut for Weekend Construction

The Chicago Transit Authority announced that every elevated Loop station will be closed from early Saturday morning until early Monday. It’s a short‑term pain for a long‑term gain – the agency is finally finishing the last phase of repairs at Tower 18, the busy rail junction where Lake and Wells streets intersect.

That work has to happen roughly every ten years, the CTA says, because that stretch is one of the busiest rail junctions in the nation. In 2025 the agency repaired two of the four track quadrants; this weekend it will finish the remaining two.

Because the Loop stations will be offline, several lines will terminate early. The Brown Line will stop at Merchandise Mart instead of looping downtown, and the Orange Line will end its run at Roosevelt. Pink Line trains will still meet the Blue Line at Racine, while Green Line cars from the South Side will also terminate at Roosevelt; the West‑Side Green service will keep ending at Clinton.

The underground Red and Blue lines are untouched and will run as usual, so riders from the South and Southwest can still hop onto the Red Line at Roosevelt. Brown Line passengers have a couple of options: they can catch the Red Line at Fullerton or hop on a free bus shuttle that will run between Merchandise Mart and the downtown Red and Blue stations.

There’s another shuttle linking Roosevelt and Clinton, providing a little extra flexibility for anyone caught out by the closures. All of these temporary measures aim to keep the city moving while the critical track work gets done.

Timing isn’t accidental. The weekend closure dovetails with the ongoing Lake Street Bridge replacement, which has already forced changes on the Green and Pink lines since October 13. By grouping the projects, the CTA hopes to limit the overall disruption.

Good news: service will return to normal at the start of Monday’s run, exactly at 4 a.m. When the Loop stations reopen, riders should notice smoother rides and fewer delays – a small price to pay for a more reliable system.
