Overview

• CDOT will fully close the 109-year-old span to cars and pedestrians starting Oct. 6, with construction running to January/early 2028 to replace the deck, substructures and CTA tracks and to modernize mechanical and electrical systems.
• Eastbound detours send drivers from Lake to Desplaines to Washington to Franklin and back to Lake, while pedestrians are routed via Canal Street to Wacker Drive on Randolph.
• Green and Pink line trains will continue to operate over the bridge except for two 12-day outages scheduled for fall 2026 and spring 2027.
• The closure overlaps other river-crossing projects, including the Chicago Avenue bridge reconstruction and State Street Bridge repairs slated to finish in November.
• Under the Chicago Avenue bridge project, Halsted Street at Chicago Avenue is already shut, the bridge was narrowed to two lanes in August, and a full closure is planned after October for replacement.
