About the RSR Bridge Access Improvement Project

Over the last 50 years, the Richmond-San Rafael (RSR) Bridge has efficiently and effectively served Bay Area travelers while seeing a steady increase in daily vehicle use in recent years. From 2009 to 2014, the Annual Average Daily Traffic (AADT) across the bridge climbed from 70,000 to 80,000 representing a 14.3 percent increase. The RSR Bridge Access Improvements will ease congestion by increasing vehicle capacity on the Bridge and providing a new route for non-motorized travelers.

The RSR Bridge Access Improvement Project is made possible by a partnership between BATA, Caltrans, the Contra Costa County Transportation Authority (CCTA), and the Transportation Authority of Marin (TAM).
