Puente-Sifón Santa Eulalia, Road bridge across Odiel River in Huelva, Spain
The Santa Eulalia Siphon Bridge extends over 2,000 meters across the Odiel River, combining vehicle traffic lanes with water supply infrastructure for the region.
The bridge opened on March 19, 1969, under Minister Federico Silva Muñoz, replacing the previous transportation system that relied on small boat crossings.
This infrastructure connects the city of Huelva with its industrial areas while providing essential water distribution to the metropolitan region and neighboring municipalities.
The bridge operates with dedicated lanes for vehicles and bicycles, serving as a primary connection point between Huelva city and its surrounding industrial zones.
The structure includes water pipelines that supply ships heading to Ceuta and Cadiz during drought periods, while supporting local chemical industry operations.
