San Francisco-Oakland Bay Bridge West Span Revitalization & Innovation Project

The San Francisco-Oakland Bay Bridge (SFOBB) West Span Revitalization and Innovation Project will make safety improvements that support the bridge's use well into the future.

The 87-year-old West Span of the San Francisco-Oakland Bay Bridge (SFOBB) – managed by the Bay Area Toll Authority (BATA) and the California Department of Transportation (Caltrans) – is the oldest bridge in the Bay Area. 

This lifeline bridge is the Bay Area’s workhorse, and one of the nation’s busiest bridges. It plays a crucial role in supporting the Bay Area workforce, handling over three million cars per month, which is 1.5 times more vehicles per lane than any other bridge in the Bay Area. 

With heavy traffic and time taking its toll, we must take steps to ensure its functionality and safety for today and for decades to come. 

Project Details

The SFOBB West Span Revitalization and Innovation Project aims to enhance the longevity and functionality of the SFOBB. Repairs and upgrades include:

  • Protective coating restoration: Restoring the protective coating on the steel bridge to prevent corrosion.
  • Structural and deck components: Repairing or replacing aged and worn structural components ensures safety and compliance with federal standards.
  • Mechanical and lighting upgrades: Upgrading lighting systems to enhance safety and efficiency. Replacing existing air and water lines to provide reliable service to maintenance crews.
  • Fender system replacement: Replace the existing fender systems (which protect the piers from impact in the event of a collision with a vessel or debris in the water), ensuring safety and uninterrupted passage for passengers and goods.


Keeping the SFOBB in a state of good repair ensures safe passage for people and goods between San Francisco and all points east across the Bay. The project will also provide jobs and economic opportunities for local and regional workers and businesses.
