TCB Road Update - April 1, 2024

Road Closed 2024

Caltrans, State and Local Officials at TTC Meeting 
Posted:  March 21, 2024 at 8:00 pm

More rocks and dirt continue to fall from the unstable hillside on TCB around post mile marker 1.8 (SR-27). Caltrans has taken drone video of the landslide and found a tension crack about 1800 feet above the highway on the steep, unstable hillside. The geologist reports that the situation is worsening beyond initial expectations. The rains this past weekend challenges the recovery effort. Caltrans cautions residents to not walk past the barriers as it is not safe.  Geologists continue to assess the best way to temporarily stabilize the hillside and to clear the roadway, Opening TCB partially or completely is unknown at this time, but everyone involved understands the urgency of reopening the roadway as quickly and safely as possible.

As of 3/22/24, Caltrans stationed workers (flaggers) to guide motorists from Tuna Canyon Road to southbound SR-1 (PCH). This will make it easier and safer for drivers to cross the PCH northbound lanes, as well as to deter wrong-way drivers from entering Tuna Canyon Road from PCH.

Caltrans also restriped the median lane on PCH south of Big Rock Drive, to provide two northbound lanes that can help alleviate traffic congestion through the heavily traveled commuter corridor. Two southbound lanes remain open. This information is provided by Caltrans Public Information Office.  DPW is assessing the other streets in Topanga (county maintained roads, like Tuna) to make sure they are free of hazards.

On another related matter:

The Topanga Town Council has made an appeal to the Principals of Paul Revere Middle School and Palisades Charter High School to grant special leniency regarding tardiness and absence to students who travel from Topanga and Malibu that are navigating challenging road conditions from the 2024 storm event.  Caltrans has implemented the Town Council's request that CMS electronic road closure signage includes the message, "Topanga Town Open". Local businesses are feeling the strain of TCB being closed from Grandview to PCH. The Council and the Chamber of Commerce ask all Topangans to shop and dine local as often as they can in support of our mom and pop stores, restaurants and event venues.

Caltrans and Topanga's government representatives answered community questions and heard comments at the Topanga Town Council meeting on 3/20/24. Read the meeting notes here.
