Los Tilos Viaduct, Road bridge in San Andrés y Sauces, Spain.
Los Tilos Viaduct is an arch bridge spanning a deep canyon on La Palma island, connecting two sides of mountainous terrain. The roadway is supported by a concrete arch that crosses the valley without relying on supports within the canyon itself.
The structure was completed in the early 2000s using innovative building methods that allowed simultaneous construction of the roadway and arch components. Its completion was a major step in improving transportation access to western island areas.
The viaduct serves as a landmark that shapes how people experience the island's landscape when traveling through the region. Locals and visitors recognize it as a symbol of modern infrastructure connecting the mountainous terrain.
The bridge is a regular road where vehicles travel daily, and wind can be stronger here than in surrounding areas. Those visiting should be comfortable driving and exercise caution in bad weather conditions.
The concrete arch features a very slender form with a rib only about 6 meters wide, which is unusually thin for bridges of this type. This narrow design makes the structure appear lighter visually while still supporting all the traffic that crosses it.
