Detail Design

The new Tacoma Narrows Bridge just south of Seattle, Washington, is the first major suspension bridge built in the United States in more than three decades. Featuring two 155-meter-tall towers and a main span 853 meters long, it will take its place alongside an existing bridge across Tacoma Narrows, connecting Gig Harbor and Tacoma. Vehicles will travel in one direction on each bridge, increasing driver safety and improving the flow of traffic. A joint venture of Bechtel and Kiewit Pacific is designing and building the new bridge, which opened to traffic in July 2007. Here are the steps in the construction of the bridge and associated roadway. For more information, go to www.wsdot.wa.gov and look under Projects.
