Ultra High Performance Fibre Reinforced Concrete (UHPFRC) is a concrete type with superior characteristics concerning strength, ductility and durability compared to conventional concrete. In spite of extensive research efforts the number of applications is still limited. In order to promote UHPFRC in the Netherlands, Cement & Beton Centrum initiated a program that aimed at designing and realizing attractive stractures with UHPFRC; the Parkbridge is one of the cases considered. This paper describes the design and the optimization of the 'Parkbridge', a slender bridge with a span of about 20 meters. This pedestrian bridge was designed to replace the existing wooden bridge of a nature park. The bridge consists of a parabolic-shaped load-bearing stmcture and an ultra-slender balustrade. A tailor-made UHPFRC was applied to produce the largest element of the balustrade. Besides design considerations, production aspects of the slender UHPFRC balustrade-element are discussed.
