A 34 million dollar project kicks off this evening on State Route 91, targeting a 14.7 mile stretch through Los Angeles County. The work involves rehabilitating overhead signage, upgrading lighting, and restoring vegetation. Caltrans describes the effort as a comprehensive modernization that also includes replacing concrete barriers and adding safety features for workers.
The first phase focuses on curbs, gutters, and sidewalks. Crews will paint lane markings and dig into the connections leading east from the 91 toward the 710 Freeway. In Compton, the westbound exit to Alameda Street and Santa Fe Avenue will shut down for bridge demolition to update railings. These initial night closures begin Monday and resume Thursday, with a break on Tuesday and Wednesday.
Traffic volume drops sharply during work hours. Between Vermont Avenue in Gardena and the Orange County line in Cerritos, both eastbound and westbound sections of the 91 will narrow to two lanes. Caltrans warns that moving blockage closures may occur as contractors shift between work sites.
Drivers face specific restrictions on Mondays and Thursdays. Eastbound lanes from Vermont Avenue to the 710 close from 8 p.m. to 6 a.m. Another section, from the 710 to the 605, closes from 9 p.m. to 6 a.m. Westbound restrictions apply from Atlantic Avenue to Vermont Avenue from 8 p.m. to 5 a.m. and from the 605 to Atlantic Avenue from 10 p.m. to 5 a.m.
Additional exits are affected. The eastbound turn to the southbound 110 Freeway closes from 8 p.m. to 6 a.m. Connections to the 605 Freeway, both north and south, see various closures between 8 p.m. and 6 a.m. on those nights. A final westbound segment from the Orange County line to the 605 closes from 11:59 p.m. to 4 a.m.
On Friday, November 13, the schedule shifts. Eastbound traffic from Vermont Avenue to the 710 closes from 8 p.m. to 6 a.m. The section from the 710 to the 605 reduces to two lanes from 10 p.m. to 8 a.m. The final eastbound stretch from the 605 to the Orange County line closes from 11:59 p.m. to 6 a.m.
All night closures starting on Monday end by 4 a.m. the following day. Caltrans projects the entire project will finish in the summer of 2029.
