I was reading in another thread about the storage that is next to POTC. This, I believe what they are referring to, is the large wood doors that are in between POTC and the Tarzan Treehouse.
I just had a thought. When I was a kid, this was actually a part of the POTC line. Then for some reason they shut this part down and installed the bridge with the line underneath that.
It seems to me if they tear out the bridge and realign the que so that it goes through the doors again, it would clear out a lot of space out front of POTC for traffic to go through. It's kind of disruptive the way they have it now, because they have traffic coming in from three different ways (Frontierland, Adventureland, and Critter Country). And then they all have to maneuver around and over the bridge.
It just seems that getting rid of the bridge and rearranging the POTC line will clear things up in that area. I know there would be a problem with Fantasmic! but no matter what you do that whole area is congested, especially during that show.
