Intersection of San Pablo Avenue and 23rd Street / Intersección de la Avenida San Pablo y Calle 23Project Overview

The San Pablo Avenue Bridge Replacement and Intersection Improvement Project (Project) is a multi-year project that will replace the existing bridge and improve the intersection at San Pablo Avenue & Road 20 & 23rd Street. 

This San Pablo Avenue bridge structure was built in 1926 and has been noted to be “Structurally Deficient.” As part of the bridge replacement, alternative intersection configurations will be analyzed to improve the safety and flow of motorists, transit, bicyclists, and pedestrians through this intersection.  Additionally, some improvements to San Pablo Creek, which flows under the intersection, may be incorporated into the project.
