One chain of quests is through a room called "Authorized Personnel Only". You get there by going through the map with the robots on it, forget what they're called. But the one that has the light bulb on them, and the ones with the tank on their back. There should be a little pillar towards the center of the room that you climb up on. The hidden street is accessible through there.
