Tips

Road cycling

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.

Road cycling

It's nice there's a way to ride across the bay, but it's really miserable. You're inches from a freeway (it's really loud). It's always cold and windy on the bridge and on the road on the east side of the bridge. The road surface on the east side of the bridge is in extremely poor condition as well.
