San Francisco – Oakland Bay Bridge is a 4.46-mile dual-bridge crossing linking San Francisco’s Rincon Hill and Embarcadero waterfront with West Oakland via Interstate 80 in California. Originally designed by chief engineer Charles H. Purcell and architect Timothy L. Pflueger, the bridge opened on November 12, 1936, six months before the Golden Gate Bridge. Today, this civil engineering landmark carries approximately 260,000 vehicles daily and draws cyclists, runners, and photographers to the Alexander Zuckermann Bicycle and Pedestrian Path on its modern Eastern Span, as well as spectators admiring the illuminated Western Span from the San Francisco waterfront.
What to Expect at San Francisco – Oakland Bay Bridge
The bridge consists of two distinct architectural halves joined at the center by a double-deck tunnel bored directly through the bedrock of Yerba Buena Island. The Western Span, connecting downtown San Francisco to Yerba Buena Island, features twin suspension bridges anchored at a central concrete pier submerged in the bay. Its upper deck carries five lanes of westbound traffic into San Francisco, offering sweeping elevated views of the Financial District skyline, the Ferry Building, and Alcatraz Island, while the lower deck carries five lanes of eastbound traffic toward the East Bay.
East of Yerba Buena Island, the Eastern Span was completely rebuilt following the 1989 Loma Prieta earthquake and opened in September 2013. Designed as the world’s largest self-anchored suspension bridge, the bright white Eastern Span is dominated by a single 525-foot-tall steel tower and a 2.2-mile skyway leading to the Oakland Touchdown. Along the southern edge of the Eastern Span runs the 15.5-foot-wide Alexander Zuckermann Bicycle and Pedestrian Path, which allows pedestrians and cyclists to travel from Oakland and Emeryville all the way to Vista Point on Yerba Buena Island.
- Western Suspension Span: The 1936 twin-suspension crossing between San Francisco and Yerba Buena Island, featuring four main towers and double-decked Interstate 80 roadways.
- Self-Anchored Suspension Eastern Span: Completed in 2013, this seismic-resilient span features a single 525-foot white steel tower and side-by-side five-lane road decks.
- Alexander Zuckermann Bike & Pedestrian Path: A 2.2-mile separated pathway along the south side of the Eastern Span connecting the Oakland shoreline to Yerba Buena Island with dedicated viewing belvederes.
- Yerba Buena Island Tunnel: A double-deck, 540-foot-long rock-bore tunnel with a 76-foot internal width, linking the Western and Eastern spans and providing exit ramps to Treasure Island.
- Waterfront Vantages at Rincon Park & Pier 14: Prime pedestrian viewing points along the San Francisco Embarcadero where visitors photograph the Western Span’s steel towers and evening lighting displays.

Visiting Tips, Getting There & Nearby Pairings
Note that pedestrians and cyclists cannot cross the 1936 Western Span between downtown San Francisco and Yerba Buena Island. To walk or cycle on the bridge, start at the East Span Trailhead off Maritime Street and Burma Road in Oakland (accessible via bike paths from Emeryville and Mandela Parkway), where free trailhead parking, portable restrooms, and drinking water are available. If approaching from San Francisco without a car, take the Muni 25 Treasure Island bus from the Salesforce Transit Center or the Treasure Island Ferry from the San Francisco Ferry Building, then walk or ride up to the Yerba Buena Island Vista Point trailhead. Motorists driving westbound into San Francisco pay an all-electronic toll via license plate or Bay Area FasTrak; no cash booths operate at the Oakland Toll Plaza.
The Alexander Zuckermann Path rises at a steady, ADA-compliant gradient (averaging 2% to 4%) with smooth pavement, separated lanes for cyclists and walkers, and wide observation bump-outs equipped with benches for wheelchairs and strollers. Strong afternoon winds frequently sweep across the bay, so bring a windproof layer even on sunny days. In San Francisco, pair bridge photography at Pier 14 and Rincon Park (home to Claes Oldenburg’s Cupid’s Span sculpture) with artisanal dining at the Ferry Building Marketplace just a 10-minute walk north along The Embarcadero, or stop on Treasure Island for panoramic skyline photos along Avenue of the Palms.
Frequently Asked Questions
What are the operating hours and best time to visit the Bay Bridge?
Interstate 80 across the San Francisco – Oakland Bay Bridge is open to vehicular traffic 24 hours a day. The Alexander Zuckermann Bicycle and Pedestrian Path on the Eastern Span is open daily from 6:00 AM to 8:00 PM (until 9:00 PM from May through October). Early morning brings the calmest winds for cyclists, while sunset and blue hour offer the sharpest light for photographing the Western Span from the San Francisco Embarcadero.
Can you walk or ride a bike all the way from Oakland to San Francisco across the Bay Bridge?
You can walk or cycle the 2.2-mile Eastern Span path between the Oakland shoreline and Vista Point on Yerba Buena Island, which is completely free. However, the Western Span between Yerba Buena Island and downtown San Francisco does not have a pedestrian or bike path, so visitors must either turn around or take the Muni 25 bus (equipped with bike racks) or the Treasure Island Ferry to complete the crossing into San Francisco.
How much does it cost to cross the San Francisco – Oakland Bay Bridge?
Walking and cycling on the Eastern Span path are completely free. For motorists, tolls are charged only in the westbound direction (heading into San Francisco) at the Oakland Toll Plaza and are collected electronically via FasTrak transponders or license-plate invoicing, while eastbound driving from San Francisco to Oakland is toll-free.
Is the Bay Bridge pedestrian path wheelchair and stroller accessible?
Yes, the 15.5-foot-wide path on the Eastern Span is fully paved, step-free, and engineered to ADA standards with a steady, moderate incline from the Oakland Touchdown to Yerba Buena Island. Both the Oakland trailhead at Burma Road and the Yerba Buena Island Vista Point provide accessible parking spaces, rest benches, and restroom facilities.
