MEADOWS PEDESTRIAN BRIDGE / SALFORD, UK
A quest for structural rationalization led us to chose the form of spatial truss developed from re-modeled hyperbolic paraboloid, with ellipses in its cross sections, to span 100m in one esthetical gesture, allowing us to have a continuous 1/20 ramp. The tubular beams in primary structure vary from 20cm of radius at the both ends, slowly declining radius till 10cm in the mid-section. Secondary structure, circles and horizontals, is used to further stabilize the form and it could be either beams or cables, depending on the cost calculation. We reached practically entirely prefabricated structure, with enormous carrying capacity. Its industrial, rusty look is not only to emphasize its identity, its spatial signature, but to visually unify two opposite characters of space; the gate, the urban portal on the street level with the accent on verticality, and the sculptural funnel in the park side, with its horizontal nature. Width of the bridge also vary from 3.5m in the mid-area, to 10m and 20m on each side, which gives possibilities for further development of the walking/cycling pattern as a sitting, performance or multifunctional zone. With that in mind, it is possible to fill certain areas between the main structure elements with glass for example, in order to obtain protected, covered zone.
