The Fruitvale Railroad Bridge spans the Estuary from Oakland to the island town of Alameda (on the right). To my eye it looks like a 1930s construction but it was actually built by the Army Corps of Engineers in 1951. It's a vertical lift bridge with railroad tracks on it that is lowered into position when trains need to cross the estuary. The Miller-Sweeney Bridge it the drawbridge next to it that carries car traffic. It was designed to raise to full height it only 66 seconds. The truth is that locals call them both the Fruitvale Bridge. Bridge fans will be happy to know there is a website for the bridges! For a picture of the bridge drawn up, go here.
