Tacoma Strait Bridge Westbound

The westbound bridge was designed and rebuilt with open trusses and reinforced pillars, and ventilation holes were opened to allow wind to pass through. It opened to traffic on October 14, 1950 and has a total length of 5,979 feet (1822 meters)-40 feet (12 meters) longer than the original bridge. Together with its parallel eastbound bridge, it forms the fifth longest suspension bridge in the United States. Because the resonance problem that caused the collapse of the front bridge has been solved by the new design, local residents gave the bridge a new nickname-"Strong Getty". When the westbound bridge was just completed, it was the third largest suspension bridge in the world. Like other modern suspension bridges, the westbound bridge is constructed of sharp steel plates instead of the original flat side steel plates. The designed daily traffic volume of the bridge is 60,000 vehicles. After completion, it opened to traffic in both directions, until the eastbound bridge was officially opened to traffic on July 15, 2007.

Tacoma Straits Bridge Eastbound

In 1998, voters in several counties in Washington State passed a bill deciding to build a new bridge. The new bridge in 2007 will be an eastbound bridge, parallel to the original bridge. Construction began on October 4, 2002 and was completed in July 2007. After completion, the original bridge will only be used as the westbound bridge. The Washington State Department of Transportation charges a $ 3 bridge crossing per train to recover construction costs. The original westbound bridge has been exempted from bridge tolls since 1965 and will continue to do so in the future. The new bridge also installed for the first time a new "Good To Go" electronic toll system.
