Overview
- The bridge will close nightly from 10 p.m. to 5 a.m. from Sept. 10 through Sept. 16, with overnight traffic rerouted via East Wacker Drive, North Columbus Drive and East Illinois Street.
- CTA bus routes 134, 135 and 136 will follow the same overnight detours and report no stops will be affected during the closures.
- The testing work is described by city officials as center break trimming and electrical testing, and the agency has said targeted repairs are planned later this year.
- Last week a routine lift jammed the span after extreme heat caused the bridge’s materials to expand, and CDOT crews cooled the structure and used mechanical adjustments to close it after hours of delays.
- The bridge carries about 102,000 vehicles daily, which helps explain why commuters and experts have questioned the decision to open the bridge for a vessel passage during extreme heat while CDOT says it must follow federal navigation requests.
