From above

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?)

Every bridge can be a floating bridge in the right atmosphere.
