Caltrans reopened Topanga Canyon Boulevard (State Route 27) on Sunday, June 2—three months ahead of anticipated following a closure due to a landslide in March.
Crews worked around the clock to “remove materials and repair the damage” in order to safely and quickly reopen both lanes of the road, which Caltrans originally estimated to remain closed until September.
“Caltrans revised its original estimate of 50,000 to 90,000 cubic yards of material needing to be removed once a geotechnical report determined that the slide was shallower than first thought,” Caltrans reported. “Crews did not encounter any anomalies in the soil during removal, which benefited the expedited opening.”
The closure, which had been in effect since March 9, had “disrupted the lives of individuals living in the canyon, visitors to Topanga and beachgoers,” according to a statement from Caltrans.
“I cannot overstate just how important it has been for the state and everyone involved to see Topanga Canyon Boulevard open as quickly and as safely as possible,” Governor Gavin Newsom said in the statement. “Thanks to the diligent efforts by the state along with crews assisting on the ground and the support of locals, this repair work has exceeded all our expectations by opening months ahead of initial estimates.”
The road will have one-lane traffic control on off-peak hours using flaggers, Caltrans reported, as emergency repairs continue. Around 15,000 cubic yards of material were removed and repurposed for various entities, including Ventura County farmers, Los Angeles County Department of Public Works and an art installation.
With the slope stabilized and material removed, geotechnical engineers and geologists will continue to monitor the site for any movement, according to Caltrans. A cable mesh drapery system may be recommended to prevent “any sloughing of remaining loose materials,” as well as planting native seeds to “further stabilize the slope.”
“I want to commend all those responsible for the quick reopening of this critical route,” Assemblymember Jacqui Irwin said in the statement. “Caltrans District 7 and the California State Transportation Agency, along with their contractors, have once again come through in record time … Thank you to all involved and in particular, thank you to the residents of Topanga who have experienced this disruption firsthand over these past months.”
