State Street Bridge Repairs to Finish by Late February, CDOT Says

Bridge trials in early March will verify the bascule’s operation before it reopens.

Overview

  • Emergency repairs began in April 2025 after a September 2024 inspection labeled parts of the 1949 bridge structurally deficient.
  • Crews identified additional steel damage during construction, extending work beyond the original mid-November timeline.
  • The project has replaced floor beams, repaired center lock components, and completed viaduct fixes north of the river on Dec. 30.
  • Nearby, the State/Lake Loop station is closed for demolition and a full rebuild into an accessible hub, with reopening planned for 2029.
  • The crossing remains closed with detours and CTA bus reroutes in place, affecting a corridor that typically carries nearly 7,000 vehicles a day.
