The plan was to ship Cybertron to Earth? Right. That's really wondrous and all, but not so scary as it sounds. Now, shipping Earth to Cybertron, that would have freaked me out. Have the pillars create a wormhole big enough to envelop the Earth and transport it away from the solar system and into Cybertron's orbit. Not only would it have generated more panic, but it would have also served as an Autobot means to return to their home, which unfortunately gets destroyed to save Earth (or something like that). Overall, the space bridge plan sounded fine, just back to front.
