VIEW BAY BRIDGE CAMERAS →The San Francisco-Oakland Bay Bridge is part of Interstate 80 and the primary motor vehicle crossing of the San Francisco Bay. Per the Metropolitan Transportation Commission (MTC), the bridge carries approximately 260,000 vehicles per day across two separate structures connected by a tunnel through Yerba Buena Island. The original bridge opened on November 13, 1936 — six months before the Golden Gate Bridge — per Wikipedia's San Francisco-Oakland Bay Bridge entry. Construction began with a ceremonial groundbreaking on July 9, 1933, when President Franklin D. Roosevelt remotely set off a dynamite blast on Yerba Buena Island. The east span collapsed catastrophically during the Loma Prieta earthquake on October 17, 1989, triggering a 24-year replacement project that completed at a cost of $6.5 billion with the new east span opening September 2, 2013. At 258.33 ft wide with 10 general-purpose lanes, the new east span holds the Guinness World Record for world's widest bridge. Caltrans, QuickMap, and 511.org operate extensive Bay Bridge camera coverage.
Bay Bridge Structure and Coverage
West Span (1936)

Bridge Alternatives — When Bay Bridge is Backed Up
The Bay Bridge is the Bay Area's most-congested crossing. Key alternatives for trans-bay travel:
- BART Transbay Tube — runs directly beneath the Bay Bridge, connecting Oakland/East Bay to SF's Embarcadero, Montgomery, Powell, and Civic Center stations. Often faster than driving during peak.
- San Francisco Bay Ferry — service from Oakland/Alameda/Vallejo to the SF Ferry Building. Longer but scenic alternative.
- San Mateo-Hayward Bridge — southerly alternative via I-92, connects San Mateo peninsula to East Bay
- Dumbarton Bridge — southerly alternative via CA-84, connects Fremont to Menlo Park
- Richmond-San Rafael Bridge — northerly alternative via I-580, connects East Bay to Marin County
- Golden Gate Bridge — northerly only (connects SF to Marin; not a Bay Bridge alternative for East Bay travel)
Pro Tip: BART Beats the Bridge at Peak Hours
During weekday rush hour, BART's Transbay Tube typically beats Bay Bridge drive times dramatically. From Oakland's 12th Street or 19th Street stations to SF's Montgomery or Embarcadero stations runs ~12-15 minutes with no traffic risk. The Bay Bridge can take 45-90 minutes during heavy incidents or peak congestion. Use 511.org Bay Bridge page plus live TrafficVision cameras to decide before you commit.
Bay Bridge vs. Chesapeake Bay Bridge (Disambiguation)
Two US bridges share the "Bay Bridge" name:
- San Francisco-Oakland Bay Bridge (this page) — I-80, California, ~260K vehicles/day
- Chesapeake Bay Bridge — US-50/301, Maryland, connects Eastern Shore to Annapolis
For SF Bay Area travel, you want this page. For Maryland coastal access, see the Chesapeake Bay Bridge guide.

Tolls are collected westbound only (into SF); eastbound is free.
Is the Bay Bridge cashless?
Yes. Per MTC, all seven Bay Area state-owned bridges transitioned to all-electronic tolling and no longer accept cash. Pay with a FasTrak transponder or set up a License Plate Account. Without either, invoices are mailed to registered vehicle owners with processing fees.
When did the new Bay Bridge east span open?
September 2, 2013 — per Wikipedia's East Span Replacement entry. The replacement project ran from 2002 to 2013 at a final cost of $6.5 billion. The new east span replaced the original east span that suffered a section collapse during the Loma Prieta earthquake on October 17, 1989.
Is the Bay Bridge the world's widest bridge?
Yes — the east span holds the Guinness World Record for widest bridge at 258.33 feet (78.74 m) carrying 10 general-purpose lanes per Wikipedia.
How do I get to Treasure Island from the Bay Bridge?
Take the Treasure Island / Yerba Buena Island exit midway across the bridge. Treasure Island was created from landfill using excavation material from the Yerba Buena Island tunnel bore in the late 1930s, and hosted the 1939-40 Golden Gate International Exposition (World's Fair) per Treasure Island Museum.
Is BART faster than the Bay Bridge?
At peak hours, usually yes. BART's Transbay Tube runs directly beneath the Bay Bridge; trips from Oakland 12th/19th Street stations to SF Montgomery/Embarcadero average 12-15 minutes with no traffic risk, while Bay Bridge drive times can exceed 45-90 minutes during heavy incidents.
Are Bay Bridge cameras free to view?
Is there a "Bay Bridge" other than in San Francisco?
Yes. The Chesapeake Bay Bridge in Maryland (US-50/301) connects the Eastern Shore to Annapolis. Unqualified "Bay Bridge" usually means the San Francisco-Oakland Bay Bridge due to its much higher traffic volume and fame, but both exist.
