一支全球团队共同建立了一座当地地标，这是澳大利亚珀斯的独特，长达370米的缆车铺设的行人桥。唤起天鹅形象以及象征土著和西方社区之间和谐的戏剧性120米的钢制拱门的建设和放置需要广泛的合作和技术解决方案。这座桥最初被称为天鹅河行人桥，不仅将Optus Stadium的顾客与公共交通和自行车设施联系起来，而且是一个社区聚会地点，带有天行，观看平台，景观美化，座位，供应商，供应商和未来的邮政编码 -线吸引力。
社区志愿者在开放之前先走过桥，以确保中央悬挂的140米跨度将在交通和风条件下保持稳定。据项目官员称，对这种性质的测试是珀斯的首次测试，并为将来的桥梁树立了先例。
The foundations consist of driven, closed-ended steel piles filled with reinforced concrete. The maximum pile diameters and lengths are 1.2 m and 40 m, respectively, says Stefano Guzzon, project controls manager at Rizzani de Eccher, one of the partners of the joint venture Swan River Pedestrian Bridge Alliance, which also includes Main Roads and York Civil.
A 12.5-tonne tuned mass damper was installed to reduce the risk of unfavorable horizontal accelerations occurring in the central deck under pedestrian loading, says Guzzon. “Pedestrian load testing was also carried out in order to ‘tune’ the TMD to the most critical frequency,” he adds.
To build the 9.8-m-wide by 72-m-high bridge, crews preassembled two 120-m-long arch components dubbed “wishbones.” Barges carried them to the site, where they were placed onto hinges installed on the river piers. The white arches contain almost 900 linear meters of fully-programmable, color-changing LED lights depending on the events being held at the stadium.
The central piers feature 20-m-long, elliptical terraced garden beds that provide seating for pedestrians. The central deck area is a shaded resting/meeting area with landscaping and aboriginal-inspired art installations.
