SAN MATEO COUNTY (KPIX 5) — A mudslide closed State Highway 35 (Skyline Boulevard) in both directions a half mile north of the Castanea Ridge Road junction in unincorporated San Mateo County about halfway between Cupertino and La Honda.
Days of soaking rain caused the hill below the section to gave way Sunday, taking a 12-foot by 40-foot chunk of the asphalt with it.READ MORE: South Bay Congressman Welcomes Afghan Refugees Arriving in Fremont
Highway 35 was shut down in both directions, as Caltrans crews worked to repair the sinkhole. One engineer told KPIX 5, it’s bad, but they’ve seen worse.
Caltrans said it hopes to open the road to one-way traffic soon, but before that the hillside has to be shored up to make sure that it does not crumble away anymore than it already has.
Work to shore up the hillside will take at least a day or so, Caltrans said.READ MORE: 4.3 Magnitude Earthquake Strikes Near Los Angeles
A transmission Sunday night on San Mateo County’s alert system said the road could be closed for a week to clean up the mess.
