The Verrugas Bridge (Spanish: Viaducto de Verrugas or, more commonly today, Puente Carrión ) in Peru is the largest railway bridge on the route of the Ferrocarril Central Andino from Lima through the valley of the Rio Rimac to La Oroya and on to Huancayo.

It stands between the towns of San Bartolome and San Jeronimo de Surco at 84.4 km at an altitude of 1800 m above sea level and supplies the railroad track high-lying on the hillside above a steep and deeply incised mountain stream.

The steel truss bridge is including a short ramp 218 m long. It is supported by two timber piers that are on large concrete pedestals on the slopes of the stream bed. It consists of 22 subjects, which are not covered, so that goes between and beside the tracks of the view in the depths. At the edge of the bridge is a pedestrian bridge is located.

The first wrought iron bridge was built as part of the construction of the track, the American Henry Meiggs in 1869 agreed with the Peruvian government. It was planned by the Baltimore Bridge Company, built under the local site manager Leffert L. Buck and commissioned in January 1873 in operation. She counted at that time the world's largest wrought iron bridges.

Was leaving the coastal region as the construction of the railway line and arrived in layers above 1000 m, occurred in the living under the worst hygienic conditions workers on an entirely new disease. The worker suffered first from a high fever, severe anemia before many (anemia ) and died due to secondary infections such as miliary tuberculosis, Shigellosen and salmonellosis. This disease was later described as Oroya fever, in their late-stage develop as Verruga peruana designated warts. The relationship between the fever and the warts was demonstrated by the fatal self-experiment of the Peruvian medical student Daniel Alcides Carrión (1857-1885), after the later the disease and (among other buildings), the bridge was named.

In March 1889, the bridge was destroyed by the rushing mountain stream and a land slide. The second bridge was designed by Leffert L. Buck as a cantilever bridge and completed the end of 1890, after six months of construction.

The third, current bridge was necessary as a replacement of the older bridge, as they could not cope with the increased traffic loads. It was built in 1937 by Cleveland Bridge & Engineering Co..
