Puente de la Alcolea, Railway viaduct in Trigueros, Spain
The Puente de la Alcolea extends 300 meters across the Odiel River, reaching a height of 70 meters above the water level.
The current reinforced concrete structure replaced the original steel lattice bridge that had served the Zafra-Huelva railway line since 1889.
The viaduct represents a significant example of industrial engineering heritage, connecting communities and supporting regional railway transportation.
Visitors can access observation points near the viaduct from both Trigueros and Calañas municipalities to view the structure and surrounding landscape.
The bridge construction process was documented in a NO-DO newsreel, capturing the transition from the iron structure to the concrete design.
