Airports board approves Dulles rail funding deal

ARLINGTON, Va. (AP) - A regional airports board has approved a funding deal for the second phase of the Metrorail extension to Dulles Airport.

The deal was hammered out last week by Transportation Secretary Ray Lahood and state and local officials.

Construction has already begun on the first phase of what will be known as Metro's Silver Line, which extends the Washington area subway service from Falls Church, Va., through Tysons Corner to Reston. It's expected to be completed in 2013.

The final stretch will continue to Dulles and into Loudoun County. That portion of the project is expected to cost at least $2.8 billion, and until last week, there had been no agreement on who would pay for it.

The Metropolitan Washington Airports Authority board approved the deal unanimously Wednesday.
