The existing Saukopf tunnel, 2.7 km in length, is a single-tube tunnel which connects the town of Weinheim, Baden-Württemberg, close to the centre of the Mannheim/Ludwigshafen conurbation, with the Odenwald in Hesse and was built in the 1990s. To improve the safety of the Saukopf tunnel, the tunnel was retrofitted with a rescue tunnel in the form of a pedestrian escape tunnel parallel to the main tunnel with a minimum cross-section (excavation area of approx. 10 m² in the westward tunnelling operation, approx. 15 m² in the eastward tunnelling operation). This escape tunnel was connected to the main tunnel by cross-passages at intervals of approx. 250 metres.
