Short span (3 to 15 m) pedestrian and bicycle bridges were designed and are planned to be built in Hungary in 1998. The main driving force of the design was the cost. Glass fiber reinforced polyester was selected as the material and pultrusion asme manufacturing process. Attention was paid to the manufacturability of the elements of the bridge and their applicability in other fields. The design was governed by stiffness (displacement and vibration) and not by strength. The erection cost of thesuperstructure is slightly higher than that of conventional bridges, but their maintenance cost are very low.
