International Garden Exhibition 1993 - Footbridge at Pragsattel across Heilbronner Strasse
Stuttgart, Germany, 1992
Two parks are separated by a busy road. The 38 m long bridge spans the road gorge and forms an archway to the city.
The idea of a tied-arch bridge was developed further by realizing a "reversed suspension bridge". The bridge consists of a polygonal arch with solid bowstrings, which is almost entirely flexible and completely stiffened against unilateral loads through the concrete deck. In reversing a suspension bridge with two single masts and spread main cables, the two flanks of the arch meet at the abutment and spread towards the arch top.
