Viaduct north bypass Rottweil
The viaduct of the north bypass Rottweil is a crossing of the federal highway 27 over the Neckar about one kilometer north of Rottweil with a total length of 295 meters. It consists of five fields with the widths of 45 m, 50 m, 58 m, 72 m and 70 m. At the end of July 1999, the construction of the bridge over the Neckar valley began; in August 2001, the bridge should originally be completed. To span the Neckar Valley, four pillars are required. The construction of the bridge cost 11 million DM.
The incremental launching method was used to build the bridge body; individual prefabricated hollow bodies were retracted from the western bridge head. Using the incremental launching method, 30 meters of the roadway were concreted. The stem itself was 42 meters long and weighed 160 tons. The prestressing steel does not run within the concrete of the bridge, but in the cavity of the bridge body.
On November 30, 2001, a large temporary auxiliary pillar of the new Neckar Bridge was blown up. At around 3 p.m., four kilograms of nitroglycerin exploded, causing the 300-ton concrete pillar to overturn. The auxiliary pillar was needed during the construction of the bridge in order to be able to overcome the span between the actual piers (72 meters). On Friday, October 18, 2002, the new north bypass Rottweil was officially opened. The height above ground is 58 m.
The Thyssenkrupp test tower is within sight of the bridge .
