This paper presents the design of an experimental prestressed Vierendeel pedestrian bridge made of ultra-high performance concrete (UHPC). The structure is designed as a permanent single-span bridge with an intermediate deck. The span of the bridge structure is 61.38 m, the total width is 6.68 m, and the clearance width of the bridge is 5.30 m. The main structure of the bridge consists of two prestressed Vierendeel beams made of UHPC with dispersed steel fibres . The main beams are composed of prefabricated parts, subsequently prestressed.
