Virginia State Route 28

Virginia State Route 28 is a primary state highway in the Commonwealth of Virginia connecting rural Warrenton area corridors to the suburban and commercial centers of the Dulles Technology Corridor, Manassas, and Sterling. The route serves as a north–south arterial linking U.S. Route 17, Interstate 66, Interstate 495, and State Route 7 while passing near Dulles International Airport, George Mason University, and multiple Tysons employment nodes.

Route description

The highway begins near Warrenton in Fauquier County and proceeds north through areas adjacent to Prince William County communities toward Manassas Battlefield and the independent city of Manassas Park. It intersects major corridors including U.S. Route 29, Interstate 66, and State Route 234 before entering Fairfax County suburban sectors near the Dulles Airport perimeter and the Dulles Technology Corridor. In the northern segments the route becomes a controlled-access arterial with grade-separated interchanges at I-495 and SR 7, providing access to the Tysons Corner Center, Reston, and Sterling commercial districts.

History

The corridor traces origins to early 20th-century road networks near Warrenton and Manassas that linked agricultural markets to regional rail hubs such as Virginia Railway Express predecessors and B&O alignments. Designation as a primary state route occurred amid mid-century highway planning that coincided with the development of Dulles International Airport, the expansion of the Interstate Highway System, and suburbanization driven by federal agencies and contractors located in Washington, D.C.. In the late 20th and early 21st centuries, the corridor was the focus of capacity upgrades, interchange reconstructions and widening projects influenced by development pressures from entities including Lockheed Martin, Booz Allen Hamilton, Capital One Financial Corporation, and federal installations like the Central Intelligence Agency's contractor network. Local and state planning referenced studies by the Northern Virginia Transportation Authority, Virginia Department of Transportation, and metropolitan planning organizations that balanced commuter flows to employment centers such as Tysons Corner Center, Dulles Technology Corridor, and George Mason University SciTech Campus.

Major intersections

The route provides critical connections with federal and state corridors. Major intersections include the termini and junctions with U.S. 17 near Warrenton, a concurrency area approaching U.S. 29 and I-66 near Gainesville and Haymarket; access to SR 234 and Prince William County arterial networks; junctions with I-495 serving Tysons Corner Center and Merrifield; and the northern terminus at SR 7 in Sterling, which links to Leesburg and Arlington County corridors.

Related projects and improvements

Numerous improvement programs have targeted capacity, safety, and multimodal access. Projects have been developed in cooperation with the Virginia Department of Transportation, the Metropolitan Washington Council of Governments, and the Northern Virginia Transportation Authority, including widening to limited-access standards, interchange modernization at I-66, auxiliary lane additions near Dulles International Airport, and pedestrian/bicycle facility integration coordinated with Fairfax County Park Authority and Prince William County Park Authority. Transit-focused initiatives have involved coordination with Virginia Railway Express, Washington Metropolitan Area Transit Authority, and local jurisdictions to improve park-and-ride access and bus rapid transit corridors serving employment centers such as the Dulles Technology Corridor and Tysons Corner Center.

Traffic and usage statistics

Traffic volumes vary by segment, with rural stretches near Fauquier County exhibiting lower average daily traffic compared with urbanized segments near Tysons and Dulles Airport. Peak-hour congestion statistics published by the Virginia Department of Transportation and regional data from the Metropolitan Washington Council of Governments show substantial commuter flows to employment hubs including George Mason University, Capital One Financial Corporation, and federal installations in Washington, D.C.. Freight movements link regional distribution centers and airport cargo operations, while crash data analyzed by the Virginia Department of Transportation and National Highway Traffic Safety Administration informed safety countermeasures and corridor redesigns.
