Wood-Log Bridge in Alto Adige

To avoid the repeated flood damage that the old bridge had suffered, the new structure was designed to span the entire gully with a width of28 metres. The bridge is constructed of round, weather-resistant larch stems and steel connectors. The structure, designed to resist compression and shearing stresses, consists oftwo parallel arches connected by cross-beams. The wood stems forming the parabolic arches are set out tangentially. Each member functions as a single-span beam cantilevered at one end. The cantilever reduces the maximum moment and, together with the cable stays, creates a balustrade in the middle. Tension cables on the underside provide wind bracing. The wood pedestrian ramps are simply bolted on top of the timber structure.
