Washington & Old Dominion Trail

Washington & Old Dominion Trail The trail is a 45-mile rail-trail corridor in Northern Virginia converted from the former Washington and Old Dominion Railroad. It connects dense urban centers near Arlington County, Virginia, suburban jurisdictions like Fairfax County, Virginia and Loudoun County, Virginia, and exurban towns such as Herndon, Virginia and Leesburg, Virginia, providing multiuse access between major transport nodes like Rosslyn, Virginia and historic termini near Purcellville, Virginia.

Route and geography

The corridor traverses the Potomac River watershed and follows alignments originally oriented toward Washington, D.C., crossing jurisdictions including Alexandria, Virginia, Falls Church, Virginia, Vienna, Virginia, and Ashburn, Virginia. It parallels major roadways and transit corridors such as Interstate 66, Virginia State Route 267, and commuter rail links to Union Station (Washington, D.C.) while threading through parklands like Bluemont Park and greenways adjacent to Four Mile Run (stream). Topography varies from riverine floodplains near the Potomac River to rolling Piedmont terrain approaching Loudoun County, Virginia, with engineered features including viaduct remnants, abutments, and converted depots proximate to sites like Herndon Station Museum and Vienna Depot.

History

The right-of-way originated as a nineteenth- and early-twentieth-century rail line connecting Alexandria, Virginia and Leesburg, Virginia with branch links toward Washington, D.C. and the Chesapeake and Ohio Railway. The corridor was operated by companies that later consolidated into predecessors of the Southern Railway and fell into disuse during the mid-twentieth-century decline of regional passenger and freight service following the expansion of Interstate Highway System corridors. Local governments and advocacy groups including regional preservationists and bicycle coalitions negotiated acquisitions and easements with railroad owners and entities such as Norfolk Southern and federal agencies during the 1970s and 1980s, culminating in phased conversions administered by county boards like the Fairfax County Board of Supervisors and organizations such as the Northern Virginia Regional Park Authority. Designations including National Recreation Trails recognized segments; interpretive installations reference railroading heritage, local industry, and wartime mobilization associated with nearby sites like Fort Myer and Fort Hunt.

Features and amenities

Infrastructure includes continuous paved surface sections, separate crushed-stone equestrian alignments in portions adjacent to historic properties such as Mount Vernon, and trailheads with parking, restrooms, and water fountains near municipal facilities like Purcellville Town Hall and Herndon Town Center. Signage provides mileage markers and wayfinding tied to county trail maps produced by agencies such as Arlington County, Virginia Department of Parks and Recreation and Loudoun County, Virginia Department of Parks, Recreation and Community Services. Historic stations and interpretive panels reference railroad figures and companies like Washington and Old Dominion Railroad Company predecessors and local architects whose designs paralleled works at sites like Union Station (Washington, D.C.). Safety features include grade-separated crossings at busy arteries and lighting installations coordinated with transit agencies such as Metro (Washington Metro) in urban segments near Rosslyn (WMATA station).

Recreation and usage

The trail supports diverse uses including commuting by bicycle to employment centers in Rosslyn, Virginia and Tysons, Virginia, recreational running associated with club events sponsored by organizations like Arlington Road Runners and charity rides coordinated with nonprofits such as American Red Cross chapters, and organized equestrian activities on unpaved sections tied to rural communities near Bluemont, Virginia. Events such as charity rides, historical tours, and pedestrian counts attract partnerships with transportation planning bodies like the Northern Virginia Transportation Commission and regional conservation organizations including Potomac Conservancy. Wildlife viewing along wooded corridors brings users into proximity with species documented by local chapters of groups such as Audubon Society affiliates and environmental monitors linked to Chesapeake Bay Program watershed studies.

Management and maintenance

Management is a collaborative framework involving county park departments—Arlington County Parks and Recreation; Fairfax County Park Authority; Loudoun County Department of Parks, Recreation and Community Services—and regional entities such as the Northern Virginia Regional Park Authority. Funding and capital improvements draw on sources including municipal budgets, state transportation grants administered through Virginia Department of Transportation, federal programs like those from the National Park Service and recreation trail funds, and private contributions from foundations and corporate sponsors such as local chambers of commerce. Routine maintenance covers pavement repair, vegetation management coordinated with utility owners like Dominion Energy, winter snow clearance in arterial sections, and public safety coordination with law enforcement agencies including Arlington County Police Department and volunteer groups such as local Friends of the Trail organizations. Planning documents and master plans produced by metropolitan planning bodies like the Metropolitan Washington Council of Governments guide long-term enhancements, multimodal connections to systems like Capital Bikeshare, and studies addressing stormwater impacts tied to projects from environmental regulators such as the Environmental Protection Agency.
