Bay Bridge Flooding Triggers Caltrans Study on Sea Level Risks in Marin County
What happened
Flooding disrupted traffic and businesses in Marin County on October 29, 2026. Caltrans is studying how rising sea levels, king tides, and stronger storms could affect the Bay Bridge and surrounding infrastructure due to increasing flood risks. The agency is specifically examining low-lying areas near the Bay Bridge Toll Plaza, where minor flooding occurred earlier this year.

Why it matters
The Bay Bridge is the third-busiest bridge in the country, carrying up to 280,000 vehicle trips each day. Caltrans projections indicate that at about three feet of sea level rise during a major weather event, the bridge approach could be impacted. This study addresses long-term risks to regional transportation access.
