(Didn't read the whole thread)
The bridges were placed there to help with Hard Drives with a more "normal" speed.
My HD is Slightly faster than average, but still slow enough, it takes longer than I would like to load up the game.
I'm sure others, such as my friends, have more normal HDs, and if they ran across the bridges too fast, this would most likely cause loading problems.

I'm pretty sure the Dev team won't allow this, until many years go by, when they think the average players HD speed is fast enough.
