The State Street Bridge over the Chicago River is finally edging toward a comeback after months of emergency work that shut it down to cars, buses and anyone on foot. The closure, in place since spring 2025, has tangled Loop travel and rerouted traffic while crews tore into the bridge’s mechanical guts and steel skeleton. Now, city officials say the home stretch is in sight.
CDOT says crews are in the final phase of emergency repairs that began in April 2025, and work is expected to wrap toward the end of February, with bridge trials slated for early March, according to CBS Chicago. After those tests, the agency plans to reopen the bridge to traffic and pedestrians, although it has not given a firm date. The department told the outlet that additional steel repairs discovered mid-project pushed the schedule past the original plan.
Why The Bridge Shut Down
The full closure came after inspections flagged “structurally deficient” elements, a city official told the Chicago Sun‑Times. The work was initially expected to last through mid November 2025. Inspectors found deterioration in load-bearing parts of the bascule bridge that needed to be replaced or reinforced, the Sun-Times reports, which led CDOT to accelerate the repair schedule. That shift has meant longer detours and altered routes for commuters and delivery drivers threading the Loop.
What Crews Have Fixed
Crews have removed and replaced floor beams and rehabilitated the bridge’s center-lock components, along with other steel repairs, work CDOT laid out when the closure began, per FOX 32 Chicago. Engineers say the fixes address alignment issues between the two leaves of the bascule span and put critical moving parts back in working order. Workers also used the shutdown to repair viaduct sections immediately north of the river, which is expected to cut down on future lane closures for follow-up work.
How Traffic And Transit Are Detouring
Northbound drivers are being sent west on Wacker Drive, then north on Dearborn and east on Kinzie before reconnecting with State, while southbound traffic is detoured west on Kinzie, south on Clark and east on Wacker Drive, CDOT told CBS Chicago. The agency also said three CTA bus routes are affected, the No. 29 State in both directions along with the southbound No. 36 Broadway and No. 62 Archer, and that concrete bus pad restoration on the viaduct has been completed or will finish soon. Pedestrians have been pushed to neighboring bridges and stations for the duration, and officials say the detours will stay in place until testing and final inspections are done.
State/Lake Rebuild Shakes Up The Block
Just south of the bridge, the historic State/Lake 'L' stop closed in early January for full demolition and reconstruction into a modern, fully accessible hub, according to transit documentation at Chicago‑L.org. The project is set to add wider platforms, four elevators, two escalators and a glass canopy, and is expected to take roughly three years, with the new station tentatively pegged for a 2029 opening. Riders are being urged to use Washington/Wabash or Clark/Lake instead while heavy demolition and excavation continue.
For now, commuters should plan on detours sticking around through testing and keep an eye on CDOT and CTA alerts for any sudden shifts. Businesses and drivers are being told to budget extra time and lean on official channels for real-time updates as crews finish the final quadrant of work and get the bridge ready for trials. If everything goes smoothly, the Loop could see a direct State Street river crossing restored before spring traffic really starts flexing.
