Highway 4 Closure Alert for Delta Travelers | San Francisco News

Highway 4 in San Joaquin County is shutting down for major pavement work—nine miles from Roberts Road to the county line—twice this summer, with closures Friday night to Monday morning. Expect 18-mile detours and 30-40 minute delays. Caltrans says full shutdowns are faster, safer, and save money—this $21M project aims to finish by February, keeping the Delta’s only crossing in top shape.
