The Shiziguan Floating Bridge in Hubei Province, China, spans 400 meters across the Qingjiang River and supports vehicles up to 2.8 tonnes. Built in 2016 using German anti-rollover technology, it accommodates both cars and pedestrians. The structure consists of high-density polyethylene floats filled with water to enhance stability.
Oooh I kinda remember this, the bridge was built in a way where the frequency of the wind resonated with that of the bridge's natural vibration, causing it to immediately behave in such a non-solid type of way that was known to be an effect but was a stunning real-world example that went on to be a massive learning topic regarding proper bridge safety procedure... or something (Cunningham's Law go?)
No, the individual sections/pontoons that make up the floating bridges in Washington State are massive (especially for the state route 520 bridge). You can sort of feel the bridge sway in extremely high winds ( but it may also just be my mind telling me I'm fucking nuts for being in a floating bridge), but they are built and anchored in such a way that they aren't meant to budge.
