LEESBURG, Va. -
Loudoun County's Board of Supervisors has narrowly voted to approve county participation in a $2.8 billion project to build the second phase of a Metrorail extension to Dulles International Airport and beyond.
The 5-4 vote Tuesday in favor had been in doubt after several supervisors questioned the cost and potential benefits.
The first $2.75 billion phase of the project is already under way and will extend the region's flagship mass-transit system from Falls Church through Tysons Corner to Reston. It is scheduled for completion in late 2013.
The second phase will be funded largely by toll increases on the Dulles Toll Road. But it also requires funding contributions from the state of Virginia and Fairfax and Loudoun counties. It includes a station at Dulles and two in eastern Loudoun County.
