Prince William Parkway

The Prince William Parkway is a road in Prince William County, Virginia. The road carries two designations. Between U.S. Route 1 (US 1) in Woodbridge and Dumfries Road (Virginia State Route 234 or SR 234) near Manassas it carries State Route 294 (formerly SR 3000). At Dumfries Road, the Prince William Parkway assumes the SR 234 designation until ending at Interstate 66 (I-66) near Gainesville.

SR 294 from I-95 to Dumfries Road was built by Prince William County in the mid1990s. The SR 234 portion from Dumfries Road to I-66 was built by the Virginia Department of Transportation (VDOT) in late1990s as a bypass of the old SR 234 through Manassas. The existing portion of SR 234 was renamed SR 234 Business. The last portion of the Prince William Parkway, an extension of SR 294 from I-95 to US 1, was built by Prince William County in 2005. On February 16, 2012, the former route designation for the Prince William Parkway, SR 3000, was changed to SR 294 by VDOT when the Commonwealth Transportation Board approved the transfer of the secondary road to a primary road for better maintenance of the parkway.[1] Signage has been updated to reflect the new numbering along with "old SR 3000" signs.

Honorary names

The SR 294 portion from I-95 to the intersection of Liberia Avenue and SR 663 (Wellington Road) has been designated the Kathleen K. Seefeldt Parkway for Kathleen Seefeldt, the former Chairman of the Prince William Board of County Supervisors. The SR 234 portion from Dumfries Road (SR 234) to I-66 has been designated the Ronald Wilson Reagan Highway for Ronald Reagan, the 40th President of the United States.


SR 234 (Prince William Parkway) and Balls Ford Road interchange

As a part of the Transform 66 project, the current at-grade intersection of SR 234 and Balls Ford Road will be converted to a diverging diamond interchange at a cost of $167 million. As a part of this project, Balls Ford Road will be realigned about .5 miles south, where the interchange will be constructed, and a new grade-separated bridge will be built over the Norfolk Southern Railroad Line. [3] In addition, Balls Ford Road would be widened from a two lanes street to a four-lane (two lanes each way), divided roadway at the interchange. The goal is to alleviate congestion for cars and trucks accessing I-66, I-95, and various warehouses in Manassas. [4] Construction is expected to begin in January 2020 and be completed by the end of 2022. [5]

Also, Balls Ford Road is expected to be widened to a four lane highway between Doane Drive and Ashton Avenue at a cost of $67.4 million. [6]

SR 234 (Prince William Parkway) and University Boulevard intersection

$24.2 million of Northern Virginia Transportation Authority funds were requested for intersection improvements at SR 234 and University Boulevard in Massasas, where a quadrant roadway intersection is planned. [7] Design and environmental work is slated to begin in Fiscal Year 2021, with construction in Fiscal Years 2022 and 2023. [8]
