You’ve landed at OAK. Your connecting flight, for some reason that probably made sense when you booked it at 2:00 AM, leaves from SFO in four hours. Or maybe you just realized that the "Bay Area" is a lot bigger than it looks on a map. Either way, getting from Oakland Airport to San Francisco Airport is a rite of passage for travelers in Northern California, and honestly, it can be a total mess if you don't time it right.
The distance is only about 30 miles. In a vacuum, that’s a 35-minute zip across the San Mateo Bridge. But we don't live in a vacuum. We live in a world with bridge tolls, Bay Area Rapid Transit (BART) delays, and the absolute chaos of the I-880 corridor.
Why the San Mateo Bridge is Your Best Friend (Usually)
If you're driving or taking an Uber, you’re almost certainly crossing the San Mateo-Hayward Bridge. It's the longest bridge in California. It stretches across the narrow part of the bay, connecting Hayward to Foster City. On a clear day, it’s actually kind of beautiful. You’re low to the water, the salt flats are shimmering, and you can see the planes lining up for their final approach into SFO.
But here is what most people get wrong: they trust GPS blindly.
If you see deep red on Google Maps near the 880/92 interchange, you are in for a bad time. That interchange is notorious. Sometimes, taking the longer route through San Jose on the 101 is actually faster, though it adds significant mileage. Most locals will tell you to just suck it up and pay the toll. As of 2026, the toll for the San Mateo Bridge is $7, collected via FasTrak. If you’re in a rental car, make sure you know how your rental agency handles those fees, or you’ll get hit with a "convenience fee" that costs more than the bridge itself.
The BART Strategy: Cheap, Consistent, and Slightly Gritty
BART is the great equalizer. It doesn’t care about traffic. If there’s an accident on the bridge, BART keeps moving. If you’re trying to get from Oakland Airport to San Francisco Airport during rush hour—say 7:30 AM or 4:30 PM—BART is arguably the only logical choice.
Here is the step-by-step reality:
First, you hop on the OAK Airtrain. It’s an automated mover that takes you from the terminal to the Coliseum BART station. It’s quick. Then, you buy a Clipper card. You can do this on your phone now, which is way easier than messing with the kiosks. You’ll take a Richmond or Berryessa line train (check the map, they vary) and transfer at a station like Balboa Park or Glen Park to a SFO-bound train.

Total time? About 70 to 90 minutes.
Total cost? Around $18 per person.
It isn't glamorous. You’ll probably see some "local color" on the train. You might have to stand with your luggage for a few stops. But you will get there. Unlike a ride-share, the price doesn't surge when it starts raining.
Rideshares: When to Just Pay the Premium
Uber and Lyft are everywhere. You can walk out of Terminal 1 or 2 at OAK and find the designated "Ride App" pickup zone. It’s well-marked.
But listen.
A ride from Oakland Airport to San Francisco Airport can fluctuate wildly in price. At noon on a Tuesday? Maybe $55. At 5:30 PM on a Friday? I’ve seen it hit $120. And that’s before the tip. If you have three people and four suitcases, the math starts to favor an XL. If you’re solo and on a budget, it’s a tough pill to swallow.
One pro tip: if the wait for an Uber is 20 minutes (which happens when a bunch of flights land at once), check the Wingz app. They specialize in airport transfers and allow you to pre-book. It’s often a flat rate, which removes the anxiety of watching the meter climb while you’re stuck behind a stalled semi-truck in Hayward.

The Myth of the Airport Shuttle
People always ask about "the shuttle."
In the 90s, airport shuttles were everywhere. Those blue vans used to circle the terminals like sharks. Today? They’re basically extinct for inter-airport transfers. Most "shuttle" services now are private town car companies like Blacklane or local operators that require 24-hour notice. You aren't going to walk out to the curb and find a shared van waiting to take you to SFO. Don't count on it.
Comparing Your Options Side-by-Side
The Solo Budget Traveler
BART is your move. It’s the cheapest way to navigate the Oakland Airport to San Francisco Airport route. Just be prepared for the transfer. It’s not a "one-seat ride." You have to pay attention to the signs.
The Family with Kids
Take an Uber. Lugging three kids and five bags through two different train systems is a recipe for a meltdown. The $70-90 is an investment in your mental health.
The Business Traveler with a Tight Turnaround
Check the traffic. If it’s green, grab a car. If it’s red, honestly, BART might be more reliable, but most corporate travelers prefer the "sit in traffic and answer emails" approach.
What Actually Happens During the Drive?
When you leave OAK, you’ll head south on Hegenberger Road. It’s not the prettiest part of town. You’ll pass a lot of fast-food joints and gas stations. You’ll merge onto I-880 South, which is essentially the spine of the East Bay.

880 is heavy. It’s full of trucks coming from the Port of Oakland.
Once you hit the San Mateo Bridge (Hwy 92), things usually move faster. The bridge is seven miles long. You’ll feel the crosswinds. Once you’re across, you’ll hit US-101 North. SFO is just a few exits away from there.
Navigating SFO Once You Arrive
SFO is a circle. Most ride-shares drop you off at the "Departures" level of whichever terminal you need (United is Terminal 3, International is... well, International). If you took BART, you’ll arrive at the International Terminal G station. From there, you have to take the SFO AirTrain (which is free) to get to the other terminals.
Give yourself more time than you think.
SFO security lines can be a nightmare, especially at Terminal 3. If you don't have TSA PreCheck or CLEAR, add an extra 30 minutes to your itinerary.
Final Practical Advice for the Journey
- Download the Clipper App: Don't stand in line at the BART kiosk. Put $20 on a digital card while you're waiting for your bags at OAK.
- Check the Bridge: If the San Mateo Bridge is closed (rare, but happens for accidents), you have to go all the way up to the Bay Bridge, through downtown San Francisco, and back down. That turns a 45-minute drive into a two-hour ordeal.
- Tolls are Automatic: If you're driving a personal car, just drive through. They'll mail the bill to the address on your registration via license plate capture.
- The "Secret" Connection: There is no secret boat or ferry between the two. People ask this all the time. The ferries go to San Francisco's Ferry Building, not the airport.
If you’re doing this transfer, the most important thing is to manage your expectations. You are crossing a major body of water in one of the most congested metropolitan areas in the United States.
Next Steps for Your Trip:
Check the current traffic on I-880 South right now using a live map tool to see if the San Mateo Bridge is backed up. If it's a "red" day, open your BART app and plan your route from the Coliseum station immediately to ensure you don't miss your SFO departure. Look up your SFO terminal in advance so you can tell your driver exactly where to drop you, as Terminal 1 and Terminal 3 are on opposite sides of the airport loop.
