Back of the napkin calculation says the MV Dali struck the Francis Scott Key Bridge with a force somewhere around ~469 meganewtons.

Numbers I started with are 114,000 tons loaded and 8 knots coming to a halt in 1 second.

If you want some comparisons for the force of the MV Dali hitting the Francis Scott Key bridge:

38 Space Shuttle solid rocket boosters at liftoff.

1/11 of the force exerted by water on the Hoover Dam's walls.

4/5th of the total force of incident photons from sunlight on the planet Earth.
