Va. officials push for aboveground Metro station at Dulles,, March 15, 2011

By: Kytja Weir and Leah Fabel

"The state of Virginia and Loudoun and Fairfax counties are pushing for the new Metrorail station at Washington Dulles International Airport to be an aboveground station near a parking garage instead of a much pricier underground station at the main terminal.
Their urgings come as a Metropolitan Washington Airports Authority board committee is expected to decide on Wednesday where to place the station as part of the 23-mile Dulles Rail project, the largest expansion of the Metro system since its original design. The authority makes the final decision where to put the station, and the full board is expected to vote in April.
The difference hinges on a 600-foot longer walk from the north garage to the main terminal at Dulles or potentially hundreds of millions of dollars more in construction costs to build a closer, underground station. . . ."
Comment:  The "600-foot longer walk" really covers a total distance of 1,150 feet as seen in this cross-sectional diagram of the two Metro station alternative locations:  Underground near the terminal and above ground at the parking garage.  There is a 450' moving walkway to make up the difference.  Just a little disingenuous-ness from MWAA.
