I am back from the security level. Shortly after resistance was forced off the bridge, robots began to modify the security level, making it a puzzle of death. One must take repulsor lifts to ledges and move counter-clockwise around the level. The elevator to the bridge has been torn out, so the only way up is to take a force bridge to the central shaft and climb inside it up to a maintenance elevator. However, I was not able to find the control that turns on the bridge and had to return before I over stayed my welcome.
