Here are two train bridges, one for the Metro Green Line light rail, over Rosecrants Ave. and Aviation Blvd. in Hawthorne, about 12 miles due north from Palos Verdes. I lived near by when my partents and I first moved to the US, and then when I started working in aviation after college. I remember the other (proper) train bridge as being the first one I saw in the New World.
