Stuttgart–Ulm Rail Project: Widderstall Tunnel

The Stuttgart–Ulm rail project is part of the new trans-European corridor from Paris to Budapest/Bratislava. The new Wendlingen–Ulm route as an element of the project crosses the Swabian Jura and is divided up into the sections Alb foothills, Alb ascent, Alb plateau, Alb descent and Ulm Station conversion in the appropriate plans. The 962 m long Widderstall Tunnel is located on the Alb plateau close to the route’s topographical highest point and is being constructed by cut-and-cover. The total cost of the tunnel will amount to 37 million euros. This report describes the tunnel and the course of construction taking the special geological aspects of building in karstified limestone into account.
