Destroying or make invisible a road bridge

[rejenorst 18]

Ok I found similar topics and have tried it all but only one command worked with serious problems and that was deletecollection.

At the mid-east side of Chernarus is a factory south of Berenzino with two bridges, a road bridge and a train bridge. The bridge with the road crossing I can setdammage to destroy it but the roads are still visible over it. If I deletecollection ((Getpos gamelogic) nearestobject id) I can make it dissapear but this causes the bridge not be seen in subsequent previews. BAsically you have to quit the game and reload ARMA2 for it to show up again.

Has anyone found a way around this?

I tried setdammage 1 to building types house, building etc and it didn't work, it just destroyed the rail bridge which was in the 50 meter parameter I set. The rail bridge is easily destroyed but not the road bridge.

Thanks in advance.
