Schänzlebrücke at Night
In 1975 the construction of the “Schänzlebrücke” (also called New Rhine Bridge) began, but was, however, finally completed in 2007. The bridge leads over the “Seerhein” (Rhine of Lake Constance) and is the second car bridge in Constance (Old Rhine Bridge). The next car bridge across the Rhine is situated 25 kilometres away at Stein am Rhein (Switzerland).
The interesting thing about the bridge is not the construction itself, but its history. The bridge is part of the B33 highway (Note: There’s a distinction between a B-Highway and A-Highway!) and leads after about one kilometre into the swiss highway A7. Originally it was planned as a highway bridge for the A81 highway. It should absorb the urban traffic in the direction of Switzerland. Although the bridge was completed in 1980, but there was from 1983 on only a temporary connection to the urban road network.
The “Schänzlebrücke” must therefore be associated with the so-called “Bodenseeautobahn” (Highway of Lake Constance), which was planned since the 1950s. The A81 motorway comes from Stuttgart to Singen and should then be singing as A881 to Constance. As I said, it should!!! The Highway A81 was then made step by step and ends now at Singen, 30 kilometres away from Constance. Before any planning of the route for the A881, the bridge over the Rhine, which should include the highway, was already realized! After over 40 years of highway design and almost 30 years of existence of the bridge, since 2007 it carries now the B33 highway as an extension of the A81 to Switzerland.
The main bridge is 304.9 metres long and is in the middle field 37 meters wide. The bridge piers have a deep foundation of up to 63 meters.
