Keeping the Chesapeake Bay Bridge-Tunnel full of clean air and empty of water. Follow the link to read the whole thing and see the slideshow:
Quiet and spare, the only clue that they control a major transportation facility is the view out of a window of cars and trucks zipping by below at 55 mph.
From these rooms, operators monitor all aspects of the tunnel with 10 cameras at each tunnel, three computers, and a control panel of buttons, lights and alarms.
When water starts collecting somewhere and pumps start running, a light and alarm are activated and stays on until the controller walks around the desk, stands before the panel and turns it off.
As I pass through the tunnels today, I shall do so with different eyes.
