Need some Help from experts (Bridge and convoy stuff)

[E69_Falke_Wolf]

Hello everyone.
I need help with the mission editor, on a topic that is probably very basic but I can't get it to work 
(I'm just starting to use the editor).

What I need: A convoy of trucks is going by road to a bridge. 
If the bridge is OK, they cross normally and continue on their way. 
If the bridge is broken, the trucks stop and wait 10 minutes. During that time the bridge is repaired. 
Once the bridge is repaired, the trucks cross and continue their route.

What I have: The truck convoy continues its route to the bridge and stops if it is broken. 
After a little time has passed, the bridge repairs itself.

What I don't have: For some reason I can't get the trucks to start moving again after the bridge is repaired. 
They seem to move a little, but they immediately stop and stay there...

Does anyone have any idea how to make this work in the simplest way possible?
(should be easy to replicate, it's for a campaign with many bridges).

Many many thanks in advance

(This is what I have)

OK, solved. I put it here in case it is useful to someone in the future.
 

It's so easy it's embarrassing  ?: simply make a formation change to "stop" when the bridge breaks (and trucks reach the bridgehead) and another change to "continue movement" when the bridge is repaired. No "Force Complete" or alternate routes or anything complicated. KISS
