Users will notice smoother pavement, improved transit access and safety upgrades
LOS ANGELES – Topanga Canyon Boulevard/State Route 27 (SR-27) users in the San Fernando Valley may have noticed a smoother, safer traveling experience.
Crews reached a milestone this month, completing just under eight miles of the 18-mile, $58.5 million SR-27 pavement rehabilitation project from Devonshire Street in Chatsworth to Mulholland Drive in Woodland Hills.
Motorists using SR-27 in the San Fernando Valley can enjoy fresh pavement as well as new striping and pavement markings, while transit users have improved access and visibility at transit stops and maintenance workers see increased safety with new access points.
Crews also upgraded existing curb ramps and made enhancements to traffic signals and pedestrian push buttons to meet updated Americans with Disabilities Act standards.
This milestone marks about 65 percent completion for the roughly 18-mile pavement rehabilitation project, which began in Chatsworth in February 2024 and extends to Pacific Coast Highway in the unincorporated Los Angeles community of Topanga.
Crews paused work between Mulholland Drive to PCH to complete emergency repairs on SR-27 from the January 2025 Palisades Fire. Some pavement rehabilitation work in Topanga restarted in April. Paving is complete from Mulholland Drive to Café on 27, but other work in this section remains.
Remaining work from Mulholland Drive to PCH will resume in mid-June. That is subject to change due to roadway conditions, progress on the Caltrans emergency project, Southern California Edison’s completion of trenching and other conditions.
General working hours will be 10 p.m. to 6 a.m. weekdays. Specific schedules will be shared in advance. Construction on the entire project is expected to be completed in summer 2027.
Details about the project can be found on the SR-27 pavement project website.
