the two bay bridges
You are looking at Oakland on your left, and the new Bay Bridge under construction alongside the current bridge. The new one is one level as opposed to the old double decker bridge that partially collapsed in the 1989 earth quake and crushed people.
You aren’t able to see San Francisco in this photo, you see Yerba Buena Island which has a tunnel bored through it and after that the bridge continues another mile or so into downtown S.F. The flat part of the island is man made. Named Treasure Island, this flat area is a partially decommissioned military base and site of the worlds fair or something way back a long time ago. Google it yourself if you’re one of those detail oriented people.
