The Bronx–Whitestone Bridge, which is of similar design to the 1940 Tacoma Narrows Bridge, was reinforced shortly after the collapse. Fourteen-foot-high (4.3 m) steel trusses were installed on both sides of the deck in 1943 to weigh down and stiffen the bridge in an effort to reduce oscillation.

The first Tacoma Narrows Bridge was a suspension bridge in Washington that spanned the Tacoma Narrows strait of Puget Sound. It dramatically collapsed on November 7, 1940. The proximate cause was moderate winds which produced aeroelastic flutter that was self-exciting and unbounded, opposite to damping.
