Eastbound 91 Freeway Near Corona Cut to Three Lanes in 55-Hour Closure, With Another Planned Next Weekend
Caltrans has narrowed eastbound State Route 91 to three lanes between SR-241 and Green River Road for culvert work, causing hours-long weekend delays. The closure ends at 5 a.m. Monday, Nov. 9, and the same restrictions return Nov. 13–16.
CORONA / ANAHEIM HILLS, Calif. — A planned 55-hour Caltrans closure on the eastbound 91 Freeway between Orange County and the Inland Empire has caused heavy delays this weekend, and the same restrictions are scheduled to return next weekend.
What is closed
Caltrans reduced the normally seven-lane eastbound 91 Freeway to three lanes between State Route 241 and Green River Road near Corona. The restrictions began at 10 p.m. Friday, Nov. 6, and are scheduled to end at 5 a.m. Monday, Nov. 9, 2026. The work is part of a $6 million project to replace an 82-foot culvert under the freeway, which Caltrans says also improves wildlife crossing.
Caltrans lists full closures of these connectors and ramps during the work:
- Northbound SR-241 to eastbound SR-91 connector
- Eastbound Gypsum Canyon Road on-ramp(s)
- Eastbound Green River Road off-ramp
CBS Los Angeles reported that two of the three open lanes are toll lanes, and Caltrans said they would be free for all drivers during the closure.
Traffic impact
ABC7 reported that drivers faced major delays Saturday evening. Some said they were stuck in bumper-to-bumper traffic for hours. Traffic spilled onto surface streets in nearby neighborhoods. Some drivers reported fewer than three lanes open at times. Traffic was moving more freely early Sunday morning, but ABC7 reported that longer delays were expected during peak travel times.
Caltrans suggests drivers take the 57 Freeway to the 60 Freeway or use Carbon Canyon Road as alternate routes.
What's next
Caltrans' project page lists a second 55-hour closure from 10 p.m. Friday, Nov. 13, through 5 a.m. Monday, Nov. 16, 2026. It says all work depends on weather and materials and may change or be canceled. The agency says drivers should expect delays and plan alternate routes.
