Puente Quillota, Concrete bridge in Viña del Mar, Chile.

Puente Quillota is a concrete bridge in Viña del Mar that spans across the Marga Marga estuary, linking residential areas on either side. The structure carries traffic between the northern and southern sections of the city and remains a key passage for local transportation.

The bridge opened in 1908 and was among Chile's first uses of reinforced concrete construction methods, introduced by a Dutch engineering company. This project helped establish new building practices across the country.

The bridge received its name from the road leading to Quillota city, replacing its original designation as the Viña del Mar Bridge.

The bridge carries traffic in one direction only, from north to south, connecting the Vergara neighbourhood on the north bank with the continuation of Quillota Street on the south side. Drivers heading the other way must use another crossing over the Marga Marga estuary.

The bridge was built by the Compañía Holandesa de Obras de Concreto Armado, a Dutch firm, and inaugurated in 1908 under mayor Juan Magalhaes. It was the first construction in Chile carried out in reinforced concrete, a technique then new to the country.
