I've only ever heard of two ships hitting bridges; both recently, both in the US, both lost power and drifted into the bridge.

At least this bridge fall like a house of cards, I guess because the masts broke first.

Barges (and other watercraft) collide with stationary objects (which includes bridges) monthly, it's just not usually in the national news and doesn't usually cause a lot of damage.

For example, from 2001 to 2017 there were 1020 medium/high severity recorded "allision" incidents by just towing vessels/barges. That's over 5 times a month. [1]

10%+ of recreational watercraft accidents are with fixed objects. [2][3]

There were 18 bridge collapses (in the US) due to vessel collisions over 53 years (1960 to 2013), so averaging roughly one bridge collapse every 3 years. [4]
