Other potentially affected ramps include Cherry Avenue, Atlantic Avenue, Paramount Boulevard, Main Street, Avalon Boulevard, Downey Avenue, Santa Fe Avenue and Alameda Street/Santa Fe Avenue.
Caltrans said motorists should allow extra travel time and use caution through the construction area. Current highway conditions and closures are available through Caltrans QuickMap.
The work is part of a $34 million project to rehabilitate and upgrade roadside and overhead signs and lighting, restore highway planting, replace guardrails and make worker safety improvements along 14.7 miles of SR-91 in Los Angeles County.
The project is expected to be completed in summer 2029. More information about the work and project notifications is available on the Caltrans SR-91 Sign Rehabilitation Project page.
