The story of Tacoma Narrows

Tacoma Narrows Bridge: Just south of Seattle, Washington, the Tacoma Narrows Bridge opened in July 2007, on schedule and on budget. At the time, the longest new suspension bridge built in the United States in 40 years, the bridge was designed and built by a joint venture of Bechtel and Kiewit Pacific. Its design and marine construction required careful consideration of hydraulics and seismic activity in this unique, deep-water environment.

Major construction work on the bridge included installing caissons for a pair of 541-foot- (165-meter-) tall towers, building the towers, spinning cables, and assembling the deck.  During the final phases, 46 deck sections—each weighing some 450 tonswere lifted and attached to suspension cables. The entire deck stretches 5,400 feet (1,646 meters) from end to end, and the main span is 2,772 feet (854 meters) from tower to tower.

The complex project involved design, construction, procurement and management of more than 140 subcontractors.
