Concerning wobble on Auckland Harbour Bridge

Did you know, that the Auckland Harbour Bridge wobbles when enough people walk on it?
But that's more than just a fun fact, the bridge wobbles so much that Waka Kotahi says it could cause "serious crushing injuries".
Despite the warnings, Waka Kotahi this year organised mass celebratory walks across the bridge in March, that were later cancelled due to the poor weather.
Documents show the agency was told years ago how to fix the shaking, but it hasn't done it.
