The southbound Highway 101 onramp at Turnpike Road remains closed due to a sinkhole located between the onramp and the right shoulder of the southbound lanes.
The sinkhole was initially discovered Dec. 27 and the ramp was closed to maintain public safety. Caltrans crews and a contractor, Granite Construction, immediately began developing a repair strategy, Jim Shivers, spokesman for Caltrans District 5, said in a news release.
On Friday, Caltrans began excavation work under an emergency contract. Construction is planned from 6 a.m. to 5 p.m. seven days a week and will include replacing the entire length of deteriorated corrugated steel pipe up to 40 feet below the surface. Weather permitting, the ramp will reopen the week of Feb. 3, Mr. Shivers said.
Motorists headed south on the 101 may enter the freeway at Patterson Avenue or State Street. Delays should not exceed 10 minutes, officials said.
The contract for the project is $1 million. Motorists are reminded to move over and slow down when driving through highway construction zones.
