On east/west streets, numbers in Berkeley increase heading east, and in Oakland they increase heading west. So if you follow Alcatraz itself from east to west the numbers: - at first decrease, from Claremont to College (in Berkeley) - jump down and then increase, from College to Dover (in Oakland) - jump back up and then decrease, from Dover to Essex (in Berkeley) - jump back down and then increase, from Essex to San Pablo (in Oakland) It's really just dumb luck that the numbers don't collide somewhere. (I have ignored Emeryville, like everyone does, but I think its addresses follow Oakland's?)
