Adenbach Viaduct Bridge Piers

The unfinished
The 1911 projected and also almost completely built "Ruhr Mosel relief line" for the Rhine and Moselbahn should lead double-railed from Neuss over Liblar, today Erftstadt, and Rheinbach to Rech and from there over the Ahr and Eifelbahn into the Saarland and Lorraine , Construction began in the winter of 1913/14 and by the end of the war most of the buildings were completed. Until the mid-20s was still working in the Ahr Valley, due to the Treaty of Versailles but only single track.
In autumn 1921 the foundation stone of the last bridge, the Adenbach viaduct, was laid. Due to the occupation of the Rhineland the work progressed only slowly, but In the winter of 1922/23, the branch-ways and tracks were laid to the Adenbachtal Viaduct. Until about 1930 was possibly further worked, the sources are ambiguous, although the economic need, certainly because of the global economic crisis, was no longer present. This manifests itself clearly in the only single-track pillars of the viaduct.
After 1933, the tunnels were tapped as a job creation measure for mushroom breeding, so for example In 1936, two harvests produced about 60 tons of mushrooms. In the war year 1943, the tunnels were rebuilt for armaments purposes. Under the name "Lager Rebstock" the vehicles for the mobile launchers for the V2 rocket were equipped in the tunnels. In this connection, it is evidenced by the Allied aerial reconnaissance that a single-track normal lane connecting railway from Sonderberg Tunnel to interchange Rech has existed. After the withdrawal of armaments production in December 1944, the tunnels were used by the civilian population as air raid shelters.
As part of the "Cold War" after 1960, the "Kuxberg" and "Trotzenberg" tunnels were expanded as a bunker for the federal government.
At the end of Ahrweiler there are still the bridge piers of the Adenbach viaduct, which are now called "Schwurfinger" and are now used as a climbing park.

The bridge piers have yet found a use for climbing and connected with rope bridge. I think super 👍 😊.

As warning fingers show the bridge pier in the sky.
