That's also a thing.

But note how the main bridge piers are on giant islands much larger than the pier itself: https://en.wikipedia.org/wiki/Dolphin_(structure)#/media/Fil...

If you really want to make it unblockable you build a bridge+tunnel. https://en.wikipedia.org/wiki/Bridge%E2%80%93tunnel

The CBBT is downstream of the bridge which collapsed. I've driven it many times.

It has tunnels because the Navy did not want the bay blocked if the bridge dropped into the water. Which is exactly what has happened in Baltimore.
