PCH to partially reopen to essential traffic; Topanga Canyon Boulevard remains closed as crews plan rock scaling and debris removal
Summary
Caltrans told Topanga residents the closure of Pacific Coast Highway will be partially lifted at 6:00 a.m. the next morning for emergency responders, essential workers and people with day passes, while Topanga Canyon Boulevard remains closed as crews remove roughly 33,000 cubic yards of mud and stabilize a large boulder.
Caltrans told Topanga residents the closure of Pacific Coast Highway (PCH) through sections affected by recent storms will be partially lifted at 6:00 a.m. the following morning for emergency responders, essential workers and people with day passes. The agency said the opening is limited, the route will operate as a work zone and traffic controls will remain in effect.
Caltrans staff said the section of Topanga Canyon Boulevard that remains closed contains roughly 33,000 cubic yards of mud — an amount the speaker compared to more than 16 Olympic swimming pools — and removing it could require about 2,400 dump-truck loads. Officials said that volume, combined with unstable geology in some areas, prevents them from giving a firm reopening date for Topanga Canyon Boulevard. Caltrans agreed to provide the community with a best estimate within a week.
Crews plan rock-scaling work on a very large, unstable boulder. Caltrans described a two-step approach: first, scaling crews will try to deflect the rock using large inflatable airbags so it breaks on impact; if the boulder does not fragment, crews said they may use explosive charges on the roadway. Any use of on-road explosives would be scheduled only after power lines in the area are de-energized by the electric utility.
Caltrans listed other temporary controls for the partial PCH reopening: one lane in each direction where allowed, a 25 mph speed limit, flashing red signals treated as four-way stops, and an official work-zone designation that could result in doubled traffic fines at officers’ discretion. Officials warned residents to expect substantial delays.
On pass issuance and access, Caltrans staff emphasized that Caltrans does not administer pass programs for municipal closures. Meeting participants said a pass center would operate from 10 a.m. to 5 p.m. at Malibu City Hall and that local authorities were prioritizing passes for Malibu and Pacific Palisades; several Topanga residents said their requests for passes had been denied and asked county and city staff to review the policy.
What was said about timing and disposal: Caltrans and partners are testing the mud for contaminants before sending it to farms or other disposal locations. If contamination is found, material will need to be hauled to an approved landfill, which could extend the timeline. Because of those variables, Caltrans declined to give a firm reopening date for Topanga Canyon Boulevard and said timelines may shift.
Community members asked for clearer, regular updates; Caltrans committed to returning to the community with an updated estimate within a week and to coordinate future information distribution with the county and local organizations.
