Whats does a exclamation mark ! mean when next to abridge on the map? Update

Hi everyone

two different things have happened while occupying a ! bridge with my forces.

1 occupied hex with my forces and notice opened up saying something like 'bridge not destroyed'.

2 same as above but notice said 'bridge destroyed'.

So ! probably means bridge is so damaged before forces moves in it collapses from attempted use.

Or bridge is set for demolition that may or may not succeed as enemy forces occupy it. As suggested below I reckon the first (damaged by use) is the most likely.
