Jauntalbrücke, Railway bridge in Ruden, Austria

The Jauntalbrücke is a railway bridge in Ruden that crosses the Drau River valley and ranks among Europe's tallest railroad bridges at 96 meters high. The structure stretches approximately 429 meters and was engineered to carry dual tracks with modern electrical systems for high-speed rail.

The bridge was planned after 1919, when the Dravograd railway junction was cut off from Austria, but the Jauntalbahn was only built from 1959. Work began in November 1959; the steel structure was closed on 24 October 1961, and the bridge opened in 1964. In 2022–2023 it was rebuilt with two tracks and electrified for the Koralmbahn.

Since 1991 the bridge has been used as a bungee-jumping platform, and the operator counted more than 40,000 jumps between 1991 and 2016. Until 2022 a footpath ran along the east side of the old bridge, from which the jumps started. A new foot and cycle path through the inside of the structure, directly beneath the tracks, opened on 24 June 2024.

A foot and cycle path runs through the inside of the bridge, directly beneath the tracks, and opened to the public on 24 June 2024. The bridge carries the Koralmbahn between Graz and Klagenfurt; regional trains have used it again since December 2023. Bungee jumping from the old eastern footpath, offered since 1991, was expected to resume from 2025.

The bridge has become known as a jumping spot for thrill-seekers and draws adventure sports enthusiasts from across the region. Since the early 1990s, thousands of people have used this location for the adrenaline experience.
