A section of State Highway 1 in Marin County is closed in both directions between Panoramic Highway and Muir Woods Road in Marin County, according to Caltrans.
Major roadwork begins Saturday night just south of the Golden Gate Bridge toll plaza and some fear it may cause accidents.
Drivers approaching the Bay Bridge from Interstate 880 or West Grand Avenue and who use FasTrak to pay for tolls will be detoured this weekend, as Caltrans and the Bay Area Toll Authority add a new FasTrak lane on the span.
Drivers will be given a month’s notice before the closure, and after that traffic will be moved permanently off of Doyle Drive and onto a new bridge, a new tunnel, and a new, temporary detour.
A significant detour is being put into place later this year to accommodate the ongoing construction project along Doyle Drive, one of the key approaches to the Golden Gate Bridge.
Caltrans unveiled a bevy of new tools Tuesday to help motorists navigate a new Bay Bridge realignment that will be put into place over Memorial Day weekend.
Engineers assessing damage to a section of the Pacific Coast Highway that collapsed north of Big Sur said the popular roadway will remain closed for at least a month until temporary repairs are finished.
