Article presents design and production of thin-walled double curved footbridge made from UHPFRC. Parameters of this relatively new cementitious material enables design very thin structures. Article presents complex theoretic-experimental program solving design and real preparation of very specific pedestrian bridge. Single-span bridge with span of 10 m and the clear width of 1.50 m with the total thickness of shell structure 30 - 45 mm was cast as a prefabricated element in one piece. Extensive research was needed to be done before production of arch double curve footbridge. Large scale mock-ups were casted and tested. Casting technology and production of formwork were tested and optimized several times. Results of experiments were compared with numerical analysis.
