Puente-Sifón Santa Eulalia, Road bridge across Odiel River in Huelva, Spain
The Puente-Sifón Santa Eulalia is a road bridge spanning the Odiel River for over 2 kilometers, carrying both vehicles and water through its dual design. The structure connects opposite banks while simultaneously functioning as a water pipeline for surrounding regions.
The structure opened in 1969 and replaced the previous ferry system that depended on small boats. This development marked a major shift in how the city and surrounding areas were connected.
The bridge links the city with industrial zones while distributing water to surrounding areas. Visitors notice how this structure serves both transportation and water supply purposes simultaneously.
The bridge has dedicated lanes for cars and bicycles with heaviest traffic during daytime hours. Walking across or driving allows you to appreciate the full scale and dual function of the structure.
The structure contains built-in water pipelines that supply ships and support chemical industry operations. This lesser-noticed feature makes it one of the region's most interesting hybrid infrastructure projects.
