MALIBU—A portion of Topanga Canyon Boulevard, known as Route 27, will be closed on Saturday, April 8 and Sunday, April 9 from 6 a.m. to 6 p.m. while Caltrans crews work to stabilize slopes that were weakened during the mudflows in January.
Route 27 stretches roughly 3.5 miles – from Pacific Coast Highway to Grand View Drive. Caltrans will be drilling bolts into rocks to secure the hillsides along the roadway. Crews will simultaneously be working on Topanga Canyon Boulevard guard rails located north of the affected area, which could result in closures of the shoulder and up to one lane of traffic, city officials said.
The same stretch of Topanga Canyon Boulevard was closed for three days in January after heavy storms caused rockslides, spilling mud and rock into the roadway. Debris was also reported near PCH and Peurco Canyon Road, where motorists were advised to use caution.
The closure will mostly affect residents of Topanga, forcing them to travel in and out of the area from the San Fernando Valley.
