Of course it is possible, but this way is not accepted in the game, two times, i arrive to move with the crane behind the barrier but i had these problems seens on the screenshot...after a long time to remove all the trucks in this bad situation, in the initial situation...
Actually this bug has some legitimacy. I wasn't even trying to smuggle any logs over the block post, just driving by and the truck and logs go crazy like they entered some force field and my truck got stuck in trees some of which were cut down by the force. This needs to be toned down. Why not just have a solid invisible barrier that nothing can get over. There's no need for this force field where things go crazy.
