Also known simply as Bay Bridge, this bridge runs across the San Francisco Bay and connects San Francisco with Oakland. With its length of more than 7 km, it ranks among the longest bridges in the world. If you want to cross a part of it, look for Bay Bridge Trail which runs from Yerba Buena Island to Oakland and has paths both for pedestrians and cyclists.
