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.
That truss bridge would make an imposing addition to a layout! Wonder how long that one is?

It's the only railroad bridge over the Salt River. In fact, it was one of the only bridges left standing after floods in 1980, and provided a vital lifeline:

Looking at the photos, the original piers were steel and not concrete.
