Maintenance work is underway on the Bay Bridge, affecting nighttime travel. The project involves work on the bridge's steel and concrete surfaces. Crews will be painting and making repairs, which requires reducing the number of lanes available.

This reduction in lanes will occur five nights a week, from Sunday through Thursday. The lane closures will be in place from late evening until early morning. Further details about the project and its expected timeline are available from Caltrans, the agency overseeing the work, which is scheduled to continue through October.
