One of the Bay Area’s critical transportation corridors remained constricted late Monday night after a storm-related mudslide brought down a telephone pole on Highway 17.

The thoroughfare linking Santa Cruz and Silicon Valley was closed to traffic around 3 a.m. Monday at Vine Hill Road, said CHP Officer Ron Simmons. Traffic quickly backed up, with both northbound lanes and one of the two southbound lanes blocked between the summit and Scotts Valley.

A partial path was cleared around 9:30 a.m. when the CHP opened up one of the southbound lanes for northbound traffic.

Simmons said he had no reports of injuries “though we did hear some talk at one point about a person trapped in a car, but I don’t know if that was related to the downed power line or to a collision.” A KGO-TV news van was caught in the mudslide, according to the station.

Crews from Caltrans and Pacific Gas & Electric Co. were called to the scene to help clear the blockage, Simmons said. There was no estimated time to reopen all lanes of the highway, according to the CHP dispatch center in Salinas.

As of 10 p.m. Monday, a notice remained on the Caltrans website urging motorists to avoid the area and use alternate routes.

However, one of those routes, Highway 9, was blocked at different points by fallen trees and mudslides.

The road closures were among several Monday following a major weekend storm. In San Mateo County, north and south lanes of Skyline Boulevard at Kings Mountain Road were closed after a tree fell into some power lines. And a mudslide blocked northbound Highway 1 in Pacifica at Reina Del Mar Avenue.

Caltrans warned motorists in fogged-in mountain areas to drive carefully, as well as to “carry traction devices” and “watch for highway maintenance personnel.” Those with campers and trailers also were advised to stay off the roadways where high wind advisories were posted.

Further complicating the Monday commute for motorists coming into the Bay Area from coastal communities, Highway 152 was closed two miles east of Watsonville at Carlton Road in Santa Cruz County because of a mudslide. Another mudslide closed the same highway one and a half miles west of Gilroy at Watsonville Road in Santa Clara County
