The Northern Virginia Regional Park Authority has purchased another one-mile section of the Washington and Old Dominion right-of-way in Arlington, bringing its ownership of the land to within two miles of the entire 42-mile strip.

The newly purchased section runs southeast from Lee Highway in Falls Church, near the new I-66 interchange, to Route 50 at Glen Carlyn Park in Arlington.

Owning the extra mile of W&OD property will allow the pary authority to tie in with Arlington's trails system.

"In future years, as funds are available, we hope to develop this new W&OD section in Arlington as we have done in Fairfax County and Falls Church," said Darrell Winslow, executive director of the Northern Virginia Regional Park Authority. Those two sections of the W&OD trail provide bicyclists, hikers and joggers with 16 miles of paved trail.

The authority has been buying the former W&OD former right-of-way a few sections at a time over the past four years under an agreement with the owners, the Virginia Electric and Power Co. Purchase price of the entire 42-mile-long property covered in that agreement was $3.5 million. The $472,000 paid for the Arlington mile is part of that total tab.

When complete, the W&OD regional trail will reach from the Potomac to the Blue Ridge and connect with scores of local parks and trail systems.
