A global team worked together to build a local landmark, the unique, 370-m-long cable-stayed pedestrian bridge in Perth, Australia. Construction and placement of dramatic 120-m-long steel arches that evoke the image of swans as well as symbolizing harmony between indigenous and Western communities required extensive collaboration and technical solutions. The bridge, originally known as the Swan River Pedestrian Bridge, not only connects patrons of Optus Stadium with public transit and bicycle facilities, but also is a community gathering spot with a skywalk, viewing platform, landscaping, seating, vendors and a future zip-line attraction.

Community volunteers walked across the bridge before it opened to ensure that the central, suspended 140-m span would stay stable under traffic and wind conditions. Testing of this nature was a first for Perth and has set a precedent for future bridges, according to project officials.

基础由驱动的，封闭式的钢堆组成，里面装有钢筋混凝土。Rizzani de Eccher的项目控制经理Stefano Guzzon说，最大的桩直径和长度分别为1.2 m和40 m。

Guzzon说，安装了12.5吨调节的质量阻尼器，以降低行人装载下中央甲板上发生不利水平加速的风险。他补充说：“还进行了行人负载测试，以将TMD调整为最关键的频率。”

为了建造9.8米宽的72米高架桥，机组人员预先组装了两个120米长的拱形组件，称为“ Wishbones”。驳船将它们带到现场，将它们放在安装在码头上的铰链上。白色拱门根据体育场的事件，包含近900米的全面编程，变色的LED灯。

中央墩的配备20米长的椭圆形梯田花园床为行人提供座位。中央甲板区域是一个带有美化环境和原住民灵感艺术装置的阴影休息/会议区。

艾琳·乔, ENR's senior transportation editor, is a native of Los Angeles and recovering New Yorker. She studied English and theater at Occidental College, where a reporter teaching the one existing journalism course encouraged her to apply for the LA Times Minority Editing Training Program. Her journalism training led to her first stories about transportation, working as a cub reporter with the Greenwich Time. Her work has appeared in the Los Angeles Times and New York Times. Many of her experiences with engineers and contractors have inspired material for her alternative theater productions way, way off Broadway. For ENR, Aileen has traveled the world, clambering over bridges in China, touring an airport in Abu Dhabi and descending into dark subway tunnels in New York City. She is a regular at transportation conferences, where she finds that airport and mass transit engineers really know how to have fun. Aileen is always eager to hop on another flight because there are so many interesting projects and people, and she gets tired of throwing her cats off her computer in her home office in Long Beach, California. She is a very conflicted Mets/Dodgers fan.
