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).
