The Dumbarton Bridge is the shortest and southernmost bridge across the San Francisco Bay. At 1.6 miles you can cross the water with nice views over the bay. Just keep an eye out for potholes, especially on the east side, as the road conditions aren't the best. That being said there was ongoing road works the last time I was in the area so hopefully things are improving.
