For nearly 40 years, the West Seattle Bridge has been a primary route connecting West Seattle to the greater Seattle metropolitan area. The bridge spans 1,300 feet and is comprised of three cantilevered segmental box-girder concrete sections that rise to a maximum height of 140 feet over the Duwamish Waterway. In March 2020, the bridge was abruptly shut down to all traffic, disrupting the lives of those traveling to and from West Seattle for what would turn out to be nearly 2.5 years. The shutdown occurred because routine inspections had identifi ed accelerated growth of cracks at a significant enough level that immediate stabilization was needed, followed by either long-term repairs or replacement of the bridge. In 2013, inspections revealed cracks forming in the webs and slabs of the bridge’s two main girders. A series of more frequent inspections was performed, which included some epoxy crack injection installation of crack monitoring technology. Between 2013 and 2019, increases in crack growth continued to cause concern. A new engineering analysis was performed, confirming exponential crack growth, which prompted SDOT to close the bridge to traffic in March 2020.
