As Zarnex ran down the opposite way of the bridge ( which is actually the right way) he spotted something that resembled a segway. He jumped aboard it and and wander the ship for the bridge going 20-30 mph. He eventually arrived at the bridge's entrants. The guards stoped him and insisted him to get of the centipede, and he insisted that he had to get across the bridge. So the guards made a deal (more or less) that they would let him cross the bridge but not with the centimeter. And so he got off and entered/crossed the bridge.
(Srry it took so long got buzy and lazy)
