Caltrans plans SR-91 overnight closures from Monday, Nov. 16, through Friday, Nov. 20, between Cerritos and Gardena. Crews will shut lanes, freeway connectors and some ramps at night while they work on a sign rehabilitation project.
The closures run every night that week. On Friday, Nov. 20, everything reopens by 4 a.m. Saturday, Nov. 21. However, Caltrans says the schedule can change because of weather or operational reasons, so check Caltrans QuickMap before you leave.
SR-91 overnight closures: lanes and connectors
Eastbound SR-91 will lose up to three lanes in several stretches. From Vermont Avenue in Gardena to I-710, the closure runs 8 p.m. to 6 a.m. From I-710 to I-605, it runs 9 p.m. to 6 a.m. Farther east, between I-605 and the Orange County line, it runs 10 p.m. to 5 a.m.
Westbound SR-91 sees similar work. Up to three lanes close from Atlantic Avenue to Vermont Avenue, starting at 8 p.m. Between I-605 and Atlantic Avenue, up to three lanes close from 10 p.m. Near the Orange County line, up to two lanes close from 11:59 p.m. to 4 a.m.
Several connectors will also close at night. They include the eastbound SR-91 connectors to southbound I-110, northbound I-710 and both directions of I-605. On the westbound side, the connectors to I-110 close too. Caltrans also lists the northbound I-110 connector to westbound SR-91, closed from 7 p.m. to 6 a.m. Rolling full closures can happen as the contractor moves between locations, and detours will be marked.
Ramp closures and what the work involves
The westbound SR-91 off-ramp at Alameda Street/Santa Fe Avenue in Compton closes for bridge demolition. Crews are upgrading the bridge railings there. In Long Beach, the westbound on- and off-ramps at Long Beach Boulevard also close for bridge demolition.
Elsewhere, crews will stripe eastbound connectors to I-710 and excavate the roadway on those connectors. The curb, gutter and sidewalk work belongs to the larger sign rehabilitation project, which has already produced closures in earlier weeks. We covered the Nov. 2-6 SR-91 ramp closures when that stage began.
How to plan around it
Because the closures start as early as 7 p.m., late-evening commuters and shift workers feel them first. So leave extra time if you drive to the ports, the airport or Orange County at night. Freight drivers heading to I-710 should expect the connector work to slow them most.
The same week, Caltrans is also paving the US-101 Cahuenga Pass overnight. Our guide to the Cahuenga Pass paving closures covers those dates. For more local road news, see our Los Angeles and California hub.
Caltrans posts new notices each week, so a schedule for Nov. 23 and later should appear on the District 7 news page. Details are accurate as of Nov. 15, 2026.
