Overview
- The concentrated 55‑hour closure that began Friday night and ended at 5 a.m. Monday reduced eastbound SR‑91 near Corona from seven lanes to three and produced multi‑hour backups that spilled onto local streets.
- Caltrans said crews finished replacing culvert segments to improve drainage and wildlife crossings and announced the planned Nov. 13–16 weekend closure will not go forward because work was completed early.
- Commuters reported slower than expected conditions during the weekend with some motorists saying fewer than three lanes were open and the paid FasTrak express lane was closed, which increased frustration.
- Caltrans directed drivers to alternate routes including SR‑57 to SR‑60, Carbon Canyon and I‑15 and urged motorists to check its QuickMap for live updates as it uses weekend closures to limit weekday disruption.
- The $6 million resilience project is due to be finished by fall 2027 and the agency may use similar concentrated weekend windows on other corridors to speed repairs, so drivers should plan alternate routes for future weekend work.
