The Drackensteiner Hang is a mountainside in the Swabian Alps at Kirchheim unter Teck in Baden-Württemberg, Germany. Bundesautobahn 8 between Stuttgart and Ulm divides into separate northbound and southbound routes on either side of the peak. The two halves of the autobahn each traverse one tunnel and a series of two or three viaducts that were designed by Paul Bonatz and built for the Reichsautobahn; the bridges were all destroyed in World War II and had to be rebuilt, and the route in one direction was only completed in the 1950s. A project to reroute the autobahn with new tunnels and bridges has been postponed indefinitely.
