Solkan Bridge

The Solkan Bridge (Slovene: Solkanski most, Italian: Ponte di Salcano) is a 219.7-meter (721 ft) arch bridge over the Soča River near Nova Gorica in western Slovenia (by railway terminology it is a viaduct). With an arch span of 85 meters (279 ft), it is the world's longest stone arch railroad bridge (and second-longest stone arch bridge, after Germany's Syratal Viaduct, a road bridge). It holds this record because later construction technology used reinforced concrete to build bridges. It was originally built to carry the Bohinj Railway in the time of the Vienna Secession, between 1900 and 1905, and officially opened in 1906.
