These two rail bridges cross the Salt River in Tempe, Arizona. The truss bridge on the right was built in 1912 and is still used by the UP. I know the concrete piers are not original and have been either strengthened or rebuilt since the bridge was new. The bridge on the left is the new light rail bridge. On top of the y-shaped concrete piers is a big steel tube space-frame type structure, and then a concrete deck on top of that.
