Peru's Bridges: Puente Bolivar (3)

Another view of Gustave Eiffel's Puente Bolivar (Puente de Fierro). This bridge was built out of little more than small angles, rods, and plates. It was designed by Eiffel and the plans and parts were sent from Europe to be assembled at the site. It's hard to imagine that this delicate structure ever supported a steam locomotive.

The towers are bolted to stone masonry piers. Diagonal elements provide lateral stability to the four tower legs. Floor beams are at each vertical member and support a concrete deck. I like the lace-like railing on the deck. I wonder if it was part of the original structure or if it was added later?

It seems strange to have such a long viaduct just to cross the Rio Chili. Perhaps it was economical to build a 500 meter long viaduct so that the track could maintain it's grade across the valley. In the map below, we can see to the east of the bridge an railroad yard and train station whose tracks used to go onto the bridge.
