The Bridge is the area on the Satellite of Love where most of the host segments take place. A series of doors lead from the bridge to the theater, and there appear to be many other ways to get from the into the theater. Based on the opening sequence of Seasons 8 - 10, where the crew is briefly seen looking out a window, the bridge is located in the upper-right sphere of the dog-bone-shaped ship.
The Bridge contains a desk where Joel Robinson/Mike Nelson/Jonah Heston and the Bots are standing behind during the host segments, with the first of the doors that lead to the theater directly behind them. On the desk is a panel of three colored lights. In some episodes in Season 8, the desk also contains a steering wheel for controlling the SOL. On the right (left for the viewer) of the door are the Hexfield Viewscreen and a window, and in the corner to the left (right for the viewer) of the door is the airlock.
In Mystery Science Theater 3000: The Movie, the bridge is seen in more detail. It turned out there is also an area in front of the desk with another steering wheel.
