[Trigger] BLock detector?

[Squiggy]

First of all, hi ^^

Well i got a little problem. In my map (a maul), sometimes creeps attack towers by random.
In order to prevent them from attacking towers i was thinking of a trigger which detects if the path to the next waypoint is blocked - if not, order the unit to stop.
Only thing is i don't know how to check if it's possible to walk to the next waypoint or not..
can one of you help me ?

Tell a really fast moving unit to walk there, and give it a time limit.

Like - if the unit can't manage to walk there within x seconds, destroy the blocking tower?
Don't know if that would work cuz some players build big mazes..
if i understood you right

It won't tell you what tower is blocking, it will just tell you there is a block.
