Ulla River Viaduct, Railway bridge in Catoira, Spain.
The Ulla River Viaduct is a railway bridge that crosses the river between Catoira and Rianxo as part of the Atlantic Axis rail network. The structure uses steel beam construction and was built to carry high-speed trains across northwestern Spain.
The bridge opened in 2015 and represented a significant advancement in Spanish rail infrastructure for high-speed travel. The project was part of broader efforts to better connect Galicia with other European regions.
The viaduct serves as a key transportation link in the Atlantic Axis rail network, connecting communities across the Galician region. It has become a recognizable landmark in the local landscape between the river banks.
The bridge is visible to visitors from various points along the river and adjacent roads. The best views can be found from the riverbanks, where the structure can be seen in full perspective.
The viaduct holds the world record for high-speed composite truss bridges, surpassing Germany's Nantenbach Bridge over the Main, which held it since 1993 with a 208 m span. It was a finalist for the IABSE Outstanding Structure Award 2016, the first Spanish structure so honoured.
