Červená railway bridge, Railway bridge in Oslov and Červená, Czech Republic

Červená railway bridge is a steel structure that spans 253 meters across the Vltava River, rising 68 meters above the water. It features three main spans and expansion devices at each end to handle temperature changes.

Built in 1886–1889 as part of the Tábor–Ražice line of the Českomoravská transverzála, the bridge opened on 20 November 1889. At 68 m it was then the second-highest bridge in Austria, after the Trisana bridge in the Alps. It was listed as a cultural monument in 1988, lost that status in 2016 and regained it on 27 October 2021 under ÚSKP 106761.

The bridge is named after Červená nad Vltavou, the village flooded when the Orlík reservoir was filled; the settlement was later demolished. Since 14 August 2024 no trains cross it, and the association Viadukt plans to convert the deck into a cultural space and a cycle path.

Railway traffic on the old bridge ended on 14 August 2024, when the parallel Schwarzenberský bridge opened 9 m to the north, so the steel span no longer carries trains. Plans call for transferring it to the Viadukt association, which wants to turn it into a cultural space and a cycle path. Until that conversion happens, access onto the structure is not arranged.

The bridge was made by Pražská mostárna for 510,000 gold coins and held together by 329,000 rivets. Before the Orlík reservoir was filled, its two stone pillars were reinforced. In 2021 it was again declared a cultural monument, forcing the Railway Administration to abandon demolition plans.
