A 1.6-mile stretch of eastbound Interstate 80 in San Francisco is shut down through early Monday as Caltrans tears into a weekend repair project. (dot.ca.gov) The closure runs from 11 p.m. Friday, April 17, to 6 a.m. Monday, April 20, between 17th Street and 4th Street on the Bayshore Freeway. Caltrans said the San Francisco-Oakland Bay Bridge will stay open during the work. (dot.ca.gov) Traffic is being rerouted off U.S. Highway 101 on the skyway, and Caltrans posted warning signs ahead of the closure before the weekend began. ABC7 reported drivers were already bracing for detours and delays as the shutdown started Friday night. (abc7news.com) Caltrans said the work is part of a broader rehabilitation of the Central Freeway and Bayshore viaducts, elevated freeway structures that carry traffic into downtown San Francisco and toward the Bay Bridge. The agency said both viaducts are 71 years old. (dot.ca.gov) The state says those structures take heavy daily traffic and face weather and seismic stress, which is why crews are replacing pavement and repairing the bridge deck now instead of waiting for more damage. Caltrans called the closure necessary to “revitalize and rehabilitate” the corridor. (dot.ca.gov, abc7news.com) The shutdown hits one of the main approaches into downtown San Francisco from the Bay Bridge side, so the disruption extends beyond the closed lanes themselves. Caltrans warned of delays on freeway approaches into the city during the weekend closure. (dot.ca.gov) Regional trip planners have been steering drivers to live alerts as conditions change. 511.org said it provides up-to-the-minute traffic and transit disruption information for the Bay Area during major closures and incidents. (511.org) Caltrans has framed this weekend as one piece of a larger San Francisco freeway rehabilitation campaign, with additional weekend closures planned for other major routes this spring. The agency’s project page lists upcoming full weekend closures tied to work on both the Central U.S. 101 and Bayshore I-80 viaducts. (dot.ca.gov) For now, the key deadline is 6 a.m. Monday, when Caltrans expects eastbound I-80 between 17th and 4th streets to reopen and the weekend detour pattern to end. (dot.ca.gov)
