Tacoma Narrows Bridge

One of the most influential engineering discoveries of the last century Tacoma Narrows Bridge was Tacoma Naroes Bridge. When the local people knew "Galloping Gelti", the large suspension bridge in Washington State shook and entered the history book. At that time, Tacoma Narrows Bridge had many records in its short lived fascination with visitors from all over the world. However, the famous bridge is not known for its creative engineering and rapid construction, unfortunately the bridge is destined to fail.

Tacama Channel Bridge was the first Tacoma Channel Bridge in 1940. This is a suspension bridge across the Tacoma Strait of Puget Sound between Washington State and Tacoma and Kissap Peninsula. It opened on 1 July 1940 and became Puget Sound on 7 November the same year. At the time of construction (and its destruction), this bridge is the length of the world's third longest suspension bridge, the main span, behind the Golden Gate Bridge and the George Washington Bridge.

The Tacoma Bridge is a pair of twin suspension bridges over the Tacoma Channel in Puget Sound, Pears County, Washington. These bridges connect the Tacoma City and the Kisap Peninsula, carry National Route 16 across the Strait (it is known as the 14 major state national roads until 1964). Historically, the name "Tacoma Strait Bridge" was applied to the original bridge opened in July 1940 with the nickname "Galloping Gertie", but it collapsed due to aerodynamic elastic flutter and reached 1950 yuan The bridge was opened in that year. Today is still a road to the west of Ssangbashi Bridge.

When opening in 1940, the Tacoma Bridge was the third longest suspension bridge in the world. The bridge crosses the Tacoma Narrows and goes to the Gig Harbor Peninsula, replacing the ferry pedestrian commuting from Tacoma and takes 3 years with a total length of 2,800 feet. Time will be created. To save cost, the lead engineer Leon Moisseiff designed a very thin frame that is 39 feet long and has only two lanes. The Tacoma Channel Bridge opened on July 1, 1940. The flow of people in the Tacoma Channel has increased significantly, but many drivers are attracted to paid bridges through not only convenience but also abnormal features of the structure. As they do in the Tacoma Channel, the bridge will swing horizontally as it strikes the wind, sometimes it will experience excessive vertical rise.
