Ummigsbachbrücke, Road bridge ruins in Seligenthal, Germany

The Ummigsbachbrücke is a bridge ruin in Seligenthal featuring three concrete arches, of which only the eastern arch remains after World War II damage. The structure once carried traffic across the valley as part of a regional road network connecting nearby towns.

The bridge was built from 1925 to 1927 as part of the Wahnbachtalstraße, a road built by unemployed workers under the "Notstandsarbeit" scheme and opened on 7 July 1927 by district administrator Eduard Wessel. On 8 April 1945 retreating Wehrmacht soldiers blew it up ahead of American troops; only the eastern arch survived. It was never rebuilt, and a winding bypass crossing the Ummigsbach about 200 m northwest replaced it.

The Wahnbachtalstraße, including this bridge, was built from 1925 to 1927 as "Notstandsarbeit" by unemployed workers, the same kind of job-creation scheme used for the Nürburgring. Refusing the work meant losing all state benefits. The road opened on 7 July 1927 under Landrat Eduard Wessel, yet it never carried much traffic because the parallel Zeithstraße was better built.

The site serves as a starting point for a walking route that leads through the valley beneath the Wahnbachtal dam. Wear sturdy shoes and watch for wet conditions along the paths.

The surviving eastern arch stands alone in the forest, while its companion Derenbach Bridge lies submerged beneath the Wahnbachtal reservoir. These contrasting fates tell the story of two neighboring bridges from the same building period.
