The original Tacoma Narrows Bridge in Tacoma, Washington, collapsed during heavy winds in November 1940. It had employed an -deep girder system, much like the I-beam girders of the Bronx–Whitestone Bridge. However, the Whitestone Bridge was shorter and wider than the Tacoma Narrows Bridge. The Bronx–Whitestone Bridge's deck was also thicker than that of the Tacoma Narrows Bridge, which was only thick to the Bronx–Whitestone Bridge's . Overall, the Bronx–Whitestone Bridge was less prone to oscillation and critical failure, as it was not as flimsy as the Tacoma Narrows Bridge. After performing a series of experiments on the bridge's design, Ammann concluded that additional measures to stiffen the Whitestone Bridge were unnecessary.
