1950
The failed 1940 Tacoma Narrows Bridge was replaced in 1950 by a new span stiffened with a web truss. To address growing congestion, a parallel bridge south of the original opened in 2007; the 1950 bridge now has four lanes of westbound traffic and the 2007 bridge four lanes of eastbound traffic.

Who rebuilt Tacoma Narrows Bridge?
Tacoma Narrows Bridge, Washington, USA In 2007, a Bechtel joint venture with Kiewit Pacific completed the longest U.S. suspension bridge built in four decades—the new Tacoma Narrows Bridge.
How many cars cross the Tacoma Narrows Bridge each day?
Engineers designed the current bridge to carry 60,000 cars a day. But, now it handles an average of over 90,000 vehicles daily. Here’s how the current Tacoma Narrows Bridge compares with other major suspension bridges in the United States.
How much did the Tacoma Narrows bridge cost to build?
The bridge cost $6.4 million; tolls started at 55 cents and were cut to 50 cents two months later when the bonds were refinanced.
Why did Tacoma bridge fail?
The Tacoma Narrows Bridge collapsed primarily due to the aeroelastic flutter. In ordinary bridge design, the wind is allowed to pass through the structure by incorporating trusses. In contrast, in the case of the Tacoma Narrows Bridge, it was forced to move above and below the structure, leading to flow separation.
