When was Galloping Gertie built?
September 1938
Tacoma Narrows Bridge/Construction started
Was the Galloping Gertie rebuilt?
The new bridge, roughly a mile long, has been under construction since 2002. The new bridge is built parallel to and south of the older bridge, which in turn replaced the original Tacoma Narrows Bridge, the famous “Galloping Gertie” built in 1940 and collapsed in a windstorm a few months later.

Why did Galloping Gertie fail?
The torsional motion began small and built upon its own self-induced energy. In other words, Galloping Gertie’s twisting induced more twisting, then greater and greater twisting. This increased beyond the bridge structure’s strength to resist. Failure resulted.
What was wrong with Galloping Gertie?
How many people died from Galloping Gertie?
The Tacoma Narrows Bridge, nicknamed “Galloping Gertie,” fell into the sound during a windstorm on November 7, 1940. The bridge’s collapse was a lesson in poor design and engineering. Luckily, no was killed or seriously hurt in the incident. One dog did die.
When did Galloping Gertie bridge open to the public?
Though the gentle wave motion didn’t put the massive bridge in any structural distress, it was clear that motorists would find it disconcerting as cars ahead of them bobbed in and out of view. In spite of the complication, the bridge was opened to the public on 1 July 1940.
Why is Galloping Gertie on the National Register of Historic Places?
The bridge became famous as “the most dramatic failure in bridge engineering history.” Now, it’s also “one of the world’s largest man-made reefs.” The sunken remains of Galloping Gertie were placed on the National Register of Historic Places in 1992 to protect her from salvagers.
Why did people stop going on Galloping Gertie?
Numerous travelers shunned the route altogether to avoid becoming seasick, whereas many thrill-seeking souls paid the 75-cent toll to traverse Gertie during her more spirited episodes. Immediately after the problem was first observed, a number of engineering professors were hired to devise a method to reduce these movements.
Why did the cables break on the Gertie?
Unable to withstand the increasingly brutal torsional twisting, a number of Galloping Gertie’s suspender cables snapped, shifting the weight of the deck onto the remaining cables. Under the increased load and enormous strain, the cables broke one by one until there were too few to support the massive roadbed.
