Pfaffenbergbrücke, Railway arch bridge in Obervellach, Austria.
The Pfaffenbergbrücke is a railway arch bridge made of reinforced concrete that spans across a deep mountain valley. The arched structure uses a single wide curve to bridge long distances without intermediate supports, making it a distinctive feature in the landscape.
The bridge was completed in 1971 as part of expanding the Tauern Railway to create better train connections through the Alps. This project improved transportation infrastructure and made train routes faster between major towns.
The bridge shapes the landscape view for train passengers traveling through the Alpine valley, becoming a familiar landmark on their journeys. It connected previously isolated communities and changed how people in the region could access other towns.
The bridge is visible from the railway line and can be observed from Tauern Railway trains, especially from certain seat positions in the train. Visitors exploring the area should know that direct access underneath or on top of the bridge is not permitted, as it is only for train traffic.
The bridge was an engineering achievement of its time, using techniques that pushed the limits of what was possible then. Calculating and planning such long spans without intermediate supports in a mountain valley was a complex challenge that engineers in the 1970s had to solve.
