Mexico's Bridges: Antiguo Puente Ferroviario de Armeria

Just upstream from the highway bridge we studied yesterday is an old railroad bridge. It is a six span through truss bridge with five short Pratt trusses and a longer Parker truss over the Armeria River. The superstructure is supported on hexagonal-shaped masonry pier walls. The abutments include long wingwalls.

There was a truck on the embankment (and a couple of workers on the bridge) when I took this photo, but I didn't have a chance to go and see if the bridge was damaged by the earthquake. Since the bridge is close to the epicenter, I would imagine the trusses sit on tall bearings that might have gotten damaged or fallen over.
