Solkan Bridge
stone arch railway bridge over Soča near Solkan, Slovenia
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.
Description
The bridge was designed by the architect Rudolf Jaussner and engineer Leopold Oerley, initially with an 80-meter (260 ft) stone arch, and built in 1904 and 1905. Its central span was built by the Viennese construction company Brüder Redlich und Berger and the end viaducts were built by the Italian construction company Sard, Lenassi & Co, incorporated in Gorizia for this project by the Italian engineer Giovanni Battista Sard of Turin. Initially a steel arched bridge was planned at this location, but later they decided to build a stone bridge instead.
In the spring of 1904 the builders had to change the project because of the light soil and increased the arch to 85 meters (279 ft). It is built of 4,533 stone blocks.
On July 19, 1906, the Bohinj Railway (Slovene: Bohinjska proga, Italian: Transalpina, German: Wocheiner Bahn) from Jesenice to Gorizia was inaugurated (the Austrian heir Franz Ferdinand travelled across the bridge).
