  • The Bridge That Galloped

    The Bridge That Galloped
    Sep 12 2026
    The Tacoma Narrows Bridge moved from the day it opened. Locals called it Galloping Gertie and drove out to enjoy it. In November 1940, in a wind well below what it was designed for, the deck stopped rippling and started twisting, and tore itself apart. June Calloway on why the physics explanation printed in textbooks for generations is wrong: this was not resonance. It was aeroelastic flutter — a feedback loop in which the bridge's own motion extracted energy from a steady breeze until the damping went negative. Plus what the wreck could and could not tell investigators, why the right answer sat in an aeronautical journal nobody in bridge engineering was reading, and the modern footbridge that found the same trap with pedestrians instead of wind.
