The MS Gulf Coast causeway comes to mind— totally destroyed- concrete sections with rebar lifted and droped off supports, as well as the Lake Ponchartrain I-10 turnaround causeway. Water moves mountains.
Hurricane Ivan’s surge wiped out I-10 bridge going over Pensacola Bay. The earlier 185 mph winds from Irma were horrifying but people should never underestimate the surge.
There are some Youtube videos of the surge from Katrina that would show people that you don’t want to be in a surge area.
