The original Tacoma Narrows Bridge opened on July 1, 1940. The original bridge received its nickname "Galloping Gertie" because of the vertical movement of the deck observed by construction workers during windy conditions. The bridge became known for its pitching deck, and collapsed into Puget Sound the morning of November 7, 1940, under high wind conditions. Engineering issues, as well as the United States' involvement in World War II, postponed plans to replace the bridge for several years; the replacement bridge was opened on October 14, 1950.
