Initial construction for new State, Lake elevated CTA station to cause some Loop lane closures

Key Takeaways:

• Construction has started on a new elevated CTA station at State and Lake in downtown Chicago.
• Initial work will close certain traffic lanes in the Loop, affecting commuters.
• The development sits at a crucial intersection of Chicago’s transit and roadway networks.
• Local outlet ABC7 Chicago reported the lane-closure warning on Aug. 18, 2025.
• Short-term congestion is expected before the transit upgrade is completed.

The Project Begins
Work is officially under way on what the Chicago Transit Authority calls a new elevated train station at the corner of State and Lake streets. According to ABC7 Chicago, crews are “ramping up” activity on the site, marking the first visible phase of the long-planned upgrade to the Loop’s transit spine.

Immediate Traffic Impact
With heavy machinery moving in, city officials have signaled that “some Loop lane closures” will follow. The narrowed roadways aim to give construction teams room to operate directly beneath the ‘L’ tracks, a setup that leaves little spare asphalt in one of the nation’s densest downtown grids. Drivers, ride-shares, and CTA buses that normally snake through State and Lake will encounter detours and potential slow-downs.

Why State and Lake Matters
State and Lake is more than just a downtown crossroads; it is a pinch point where rail, bus, car, bike, and foot traffic converge. Upgrading the elevated stop promises smoother transfers and, eventually, faster boarding for thousands of daily riders. For now, though, the price of progress is measured in orange cones and lengthened commutes.

Looking Down the Line
ABC7 Chicago did not specify how long the lane closures will last, nor when the new station is expected to open. What is clear is that the project signals another step in the CTA’s broader push to modernize century-old infrastructure in the Loop. Until ribbon-cutting day arrives, motorists and riders alike will be navigating a work zone in the heart of the city.

Plan Ahead
The transit agency and city traffic engineers urge travelers to monitor alerts and consider alternate routes. As one CTA spokesperson has often put it in similar projects, “A little patience now will pay off in a smoother ride later”—a sentiment likely to be tested in the months ahead.
