Resumen

Located in northern Spain, in the city of Oviedo, the Santullano footbridge serves as a key component of the city's urban redevelopment project, transforming the A-66 highway corridor into a pedestrian and cyclist friendly area. This semi-circular, cable-stayed footbridge spans 84.50 meters and is supported by a single pylon with a slightly fusiform shape. The hanger arrangement is set in a fan like pattern, simulating a hyperbolic paraboloid surface that enhances the structure's visual impact and spatial complexity. With a distinct visual presence by day and night, the bridge strengthens connectivity between neighbourhoods separated by the highway, serving as a symbolic gateway.
