Editing Golden Gate Bridge (section)

===Torsional bracing retrofit===
On December 1, 1951, a windstorm revealed swaying and rolling instabilities of the bridge, resulting in its closure.<ref>{{cite news |last1=Van Niekerken |first1=Bill |title=When the Golden Gate Bridge was closed by a violent storm |url=https://www.sfchronicle.com/thetake/article/When-the-Golden-Gate-Bridge-was-closed-by-a-7971512.php |access-date=August 2, 2020 |date=June 13, 2016}}</ref> In 1953 and 1954, the bridge was retrofitted with lateral and diagonal bracing that connected the lower chords of the two side trusses. This bracing stiffened the bridge deck in torsion so that it would better resist the types of twisting that had destroyed the [[Tacoma Narrows Bridge (1940)|Tacoma Narrows Bridge]] in 1940.<ref>{{Cite web|url=https://goldengate.org/exhibits/bridge-deck-torsional-resistance-retrofit.php|title=Resisting the Twisting|website=Golden Gate Bridge Highway and Transportation District|access-date=July 29, 2019}}</ref>
