Overview
- The CTA will halt all elevated Loop service from 4 a.m. Saturday, Oct. 24 until 4 a.m. Monday, Oct. 26 to complete track and signal work at the Loop‑Lake junction.
- Brown, Green, Orange and Pink line trains will run shortened segments instead of circling the Loop while shuttle buses and station transfers bridge gaps.
- The Red and Blue subway lines are not affected and are being promoted as alternative downtown routes for riders.
- CTA plans include specific transfer points such as Roosevelt for Red Line access and Racine for Pink-to-Blue transfers, and the agency will deploy signage, customer alerts and shuttle stops to guide riders.
- This weekend’s work continues the multi-year Lake Street Bridge reconstruction that began in October 2025 and follows earlier staged outages, with officials warning more temporary disruptions are planned as reconstruction proceeds.
