Carquinez Bridge stretch of I-80 will be closed this weekend starting Friday night
Brace for traffic delays: Carquinez Bridge and US 101 construction projects
Work begins Friday night on the Carquinez Bridge, which will see a stretch of the bridge shut down for the weekend starting Friday night. A portion of U.S. Highway 101 in San Francisco will also see repair work that starts Friday and lasts through the weekend.
VALLEJO, Calif. - Caltrans is advising drivers of an upcoming major Bay Area road closure. The westbound lanes of the Carquinez Bridge, officially named the Alfred Zampa Memorial Bridge, will be closed, starting Friday night and lasting through early Monday morning, due to construction.
Bicycle riders and pedestrians should also be aware that the bridge's path will be closed.
The bridge connects Vallejo in Solano County to Crockett in Contra Costa County.
Construction projects around the Bay this weekend
Construction projects on both sides of the Bay this weekend could cause major traffic delays along Highway 101 in San Francisco and near the Carquinez Bridge.
The schedule
The construction of the nearly one-mile stretch is scheduled to begin on Friday, August 21, at 10 p.m. and continues through the weekend, until Monday, August 24, at 3 a.m.
Drivers should plan ahead and expect delays in the area. Caltrans has provided detour maps that show alternate routes.
Drivers traveling toward San Francisco will be detoured onto I-780 toward Benicia, where they can merge onto Interstate 680 and cross the Benicia-Martinez Bridge. Eastbound I-80 traffic across the Carquinez Bridge will remain unaffected.
Major construction projects this weekend in the Bay Area
Bay Area drivers should brace for delays this weekend. Caltrans is preparing for two major construction projects, one of which will shut down the Carquinez Bridge. The other will shutdown a busy stretch of US 101 in San Francisco.
The construction
Crews are expected to repave the entire westbound bridge deck. Caltrans maintenance crews will also be working at the foot of the bridge to Highway 780 in Vallejo. There, they will do maintenance work, vegetation control, in addition to litter and graffiti clean up.
Crews need the extended closure to grind out and replace a 23-year-old, one-inch layer of asphalt sitting on top of the steel deck.

101 construction in San Francisco
Another major bottleneck this weekend will be the partial closure of San Francisco's Hospital Curve, where Caltrans will remove and replace the concrete median.
From 11 p.m. Friday until 5 a.m. on Monday, Caltrans is closing half the lanes for the median replacement as well as drainage work.
"We're gonna take two of the four lanes, both southbound and northbound, in order to get some of the work done on that structure," said Bart Ney Caltrans' chief district information officer.
