One thing I saw was making the foot bridge infantry only by putting down impassable terrain to make a land-bridge. I saw this in exactly -one- scenario and found it rather clever, but no good if you want smaller vehicles to pass. Like others said, the best you can do if you want jeeps and the like but no tanks is to write up some house rules and make the players super-duper pinky-promise to obey them.
