The Goodwill Bridge is Australia‘s longest footbridge extending 400 metres from Brisbane‘s Botanic Gardens to South Bank across the Brisbane River. In order to activate the journey, the bridge is conceived in three parts - one as a pier rising to a central pavilion, one a clear span of 120 metres, and the third a rampart descending into South Bank through the Queensland Maritime Museum. The central pavilion acts as a mass to resist vessel impacts and is detailed such that its sculptural form creates precise lines of resistance. The structural design corresponds to the three journey parts, each ramp being differently supported on posts and the central span supported by a dual arch tilted toward the prevailing winds. The arch and Gardens ramp intersect at an angle with the ramp extending beyond the intersection to form a canti levered deck for events and relaxation. This deck is suspended from a mast and cable structure which also supports the end of the dual arches at a pin-joint. This hybrid structure generates interesting connection details.
