Two lanes of Pacific Coast Highway south near Big Rock Drive will remain closed until Tuesday morning as crews work to repair roadway damage caused by a private contractor drilling under the highway, according to Caltrans.
The drilling work caused a “bulge in the roadway,” forcing the closure of one lane in each direction, Caltrans spokesman Patrick Chandler said.
Chandler said the contracting company, which was working on a private residential construction project, hit a large rock while drilling under the road, causing the damage.
The lane closures could last until 8 a.m. Tuesday, and traffic delays are expected.
“This could cause some serious backup,” Chandler said.
He added that the damaging work was done solely by a private contractor, and was not related to a nearby Caltrans wave-breaker project at Las Tunas Beach, which also has caused lane closures from La Tuna Canyon Road to Topanga Canyon Boulevard.
