Safety is the top priority, please stay off closed roads.
Topanga Canyon Boulevard (SR-27) remains closed to the general public for safety reasons between State Route 1 and Grand View Drive as extensive cleanup and repairs continue. Three crews have been working day and night in the emergency repair area.
While the closure remains in place, access has expanded to allow escorted school buses during designated times. Access is also permitted to law enforcement for public safety. Caltrans asks the public to heed the closure points and avoid the area for their safety as debris removal and repair work take place.
Caltrans and its partners continue to work on rebuilding and restoring the roadway by restoring retaining walls at three locations (postmiles 2.363, 2.52 and 2.712), the shoulder and a lane where the road was washed away. Caltrans is also installing debris flow barriers and larger culverts and clearing debris from nine locations where slides occurred. Through April, work will focus on a slide area near postmile 2.52 to install a new drainage system and culverts, as well as temporary paving to allow for one lane traffic through that location. Many of these improvements will help minimize the impacts of future debris/mudflows due to the extensive burn scars in the canyon.
Caltrans' contractor is making good progress on clearing storm debris. Debris removal from the February slides is nearing completion, with all 33,000 cubic yards of mud and debris cleared. To date, all dirt has tested clean. This material has been hauled out to farms in Somis and is also being used to replenish state park land impacted by the fire and storms. The storm that came in on April 26 brought down more debris, but that has been cleared.
The contractor is also conducting boring tests to determine how deep to drive the piles for the walls. Once they place K-rail and install the traffic signals for one-way traffic control, Caltrans can open the emergency repair section.
Extensive utility work continues with Southern California Edison undergrounding utility lines and the Los Angeles County Department of Public Works rerouting a water main connection that was exposed when the road washed away.
Caltrans and its partners aim to partially reopen Topanga Canyon Boulevard with one-way traffic control within two months.
