Jefferson Lab's three end stations are connected to each other by this passageway. It is about 35 feet underground, and is about at sea level. The metal trays running along the walls hold thousands of wires, just like ones used for cable TV. The cables transmit information from the experiments up to the control rooms upstairs.
