PHX Sky Train flies over an active taxiway

Phoenix Sky Harbor International Airport is building an automated, electrically-powered train. Phase One will transport travelers between the METRO light rail, East Economy Parking and Terminal 4, Sky Harbor’s busiest.

The PHX Sky Train should begin operating in early 2013 and riding on it will certainly be quite thrilling because, as you can see above, one portion of the train line includes the only bridge in the world to be constructed over an active airport taxiway. This one is more than 100 feet tall and large enough for a Boeing 747 to pass below.
