Although MIT’s basement tunnel system is a truly impressive network connecting a large span of MIT’s buildings, one hears less about MIT’s extensive connections above ground. MIT’s buildings generally follow the rule of connection on the third floor, and illustrated here is the system of connections among MIT buildings (without the buildings themselves depicted) in the second floors of the main buildings and the third floors elsewhere.
I took the liberty to assign waypoints to this map, just like how the basement tunnel system has waypoints.
Notice that Building 24 is not included. I decided that since Building 24’s floor-numbering scheme falls in the main building category, it should be its second floor that would be included in the system if it connected, and since the third floor of 34 only connects to the third floor of 24 and not its second floor, Building 24 is not part of this system.
