Make sure you consider the geometry of driving up and over the bridge when thinking about manipulator to push the bridge down. A bridge "level" should be a foot off the ground, while a bridge tipped the other way is two feet off the ground. Are you planning on pushing it down to drive over for yourself or do you also intended to be on the opposite side manipulating it for another bot on your alliance to drive up it?

If you build the team version of the bridge it should run you less than $150 in plywood, 2x4s, hinges and plastic sheet to simulate the actual bridge surface.

We put one together the other evening, it is heavy and it does take up a bunch of space.
