Following the spectacular linkage in November 2006, the world’s longest arch-shaped bridge for pedestrians couldbe released in the spring of 2007. With a span of 230 metres, the steel and concrete construction that cost some 5.7 million euros passes over the Rhine, at an inclined angle, between Weil on the Rhine and the Alsatian town of Huningue. The main support element is a vertical arch located on the northern side. It is put together using two hexagonal, welded box cross section. The southern arch made of circular tube rests against the northern arch with an inclination of 16°.

Since July 2006, the asymmetrically formed steel arch bridge has been welded together on an assembly site situated in France. Following that, the 250 meter long bridge building was moved on floating pontoons and pulled upstream for one kilometre by means of cable winches by closing shipping and put crosswise there for the actual floating-in process. A laser measuring system monitored accurate floating-in and lowering of the 1,000 tons heavy bridge construction. In June 2007, the Rhine footbridge will be inaugurated under attendance of prominent political figures from Germany and France.
