Where is the Malleco Viaduct, a railway bridge over the Malleco River Valley?
The Malleco Viaduct is a railway bridge located in central Chile, passing over the Malleco River valley, south of Collipulli in the Araucania Region. It was opened by President José Manuel Balmaceda on October 26, 1890. At that time, it was the highest such bridge in the world. The Panamerican Highway passes right next to the viaduct.
