Puente de la Alcolea

Puente de la Alcolea is a railway viaduct made of reinforced concrete that crosses the Odiel River valley with impressive vertical clearance. The structure features multiple arches that span across the landscape in a series of supporting legs.

The original steel lattice structure was built in 1889 for the Zafra-Huelva railway line and served train traffic for decades. A new concrete construction later replaced the iron bridge to meet growing demands of rail transport.

The viaduct shapes how locals see their landscape and serves as a symbol linking the two municipalities together. It remains part of daily life for people in the region.

The viaduct can be viewed from several vantage points accessible from both nearby municipalities. The best views are available from the riverbank and surrounding hillsides.

The structure was documented in a NO-DO newsreel during the 1960s, capturing the transition from the old iron structure to the new concrete version. This film is today an important record of Spanish engineering history.
