The Loa Viaduct , also known as the Conchi Viaduct , is a former railway bridge in the Antofagasta region in Chile , which crosses the Río Loa at a height of 103 m near Conchi . The 244 m long scaffold pier viaduct has seven pillars and was the second highest railway bridge in the world when it was completed in 1888.
history
The Loa Viaduct was built in 1888 for the Ferrocarril de Antofagasta a Bolivia and leads the railway from Antofagasta to Ollagüe about 70 km to Calama over the river. The contractor was the English Horseley Ironworks in Tipton , who built the bridge under the direction of Edward Woods. It was once one of the most important structures on the railway from Antofagasta to Bolivia and one of the highest railway bridges in the world. The height was only exceeded by the Garabit Viaduct in France ; the Malleco Viaduct , completed a year later, is a few centimeters deeper than the Loa Viaduct.
In 1914, in connection with the re-gauging of the line from 76 cm gauge to meter gauge, it crossed the Rio Loa about six kilometers above the viaduct. Today only pipes and a closed driveway lead over the bridge. In 2012, the bridge in a remote area of Chile gave a neglected impression.
