Eisenbahnviadukt Stefansbachtal, Railway viaduct in Gevelsberg, Germany.

The Eisenbahnviadukt Stefansbachtal is a stone bridge featuring five arches that spans roughly 90 meters across the valley and stands about 24 meters tall. The structure connects both sides of the valley using ashlar masonry with detailed stonework visible on the pillars and vaults.

The viaduct was built in 1911 and served the Witten-Schwelm railway line until the early 1980s. After the railway closed, the stone structure remained standing and was later given extensive restoration work.

The viaduct is built from quarry stone masonry, a technique that shaped the appearance of the Witten–Schwelm line. The railway itself opened in 1934, more than two decades after the bridge was finished, and was shut down in the early 1980s. The structure has stood without trains since then and was renovated in 2021.

The viaduct stands at kilometre 14.5 of the former Witten–Schwelm line, in the Stefansbach valley in Gevelsberg. The railway was closed in the early 1980s, so the structure is no longer crossed by trains; the stonework was renovated in 2021. Visitors reach it on foot through the valley.

The viaduct stands at kilometre 14.5 on the former Witten–Schwelm line, which opened in 1934 and was closed in the early 1980s. The bridge itself is older than the railway it carried: it was built in 1911, more than two decades before trains ran over it.
