State Route 234

State Route 234 travels 34.37 miles within Prince William County, extending northwest from Dumfries to Manassas and Woolsey. Beginning at U.S. 1 (Richmond Highway) in northern reaches of Dumfries, SR 234 (Dumfries Road) proceeds northwest along a four lane route 0.33 miles to a six ramp parclo interchange with I-95. Dumfries Road (Route 234) lines Prince William Forest Park and Montclair beyond the commercial area surrounding the exchange with I-95, turning north at Independent Hill. Crossing the Occoquan River ahead of Manassas, State Route 234 resumes a northwest course to bypass the independent city to the south.

Prince William Parkway (SR 294) angles southwest to meet SR 234 ahead of Dumfries Road, which leads SR 234 Business into downtown. Prince William Parkway joins SR 234, continuing the route northwest as a four lane controlled access expressway to Manassas Regional Airport (HEF) and SR 28. State Route 28 enters Manassas from the southwest, meeting Route 234 (Prince William Parkway) at a cloverstack interchange north of HEF Airport. Beyond SR 28 (Nokesville Road), Prince William Parkway advances SR 234 northwest through business and industrial parks on a 4.57 mile long course to a trumpet interchange with I-66 near Conway Robinson State Forest.

SR 234 combines with I-66 for a 2.58 mile overlap east to the succeeding interchange with SR 234 Business (Sudley Road), turning north toward Sudley Springs. Sudley Road (SR 234) reduces to two lanes north of Interstate 66, entering Manassas National Battlefield Park en route to U.S. 29 (Lee Highway). Route 234 passes through the 5,073 acre historic park, meeting U.S. 29 near its center. Sudley Road bends westerly at Sudley Springs, leading SR 234 an additional 5.32 miles to its conclusion at U.S. 15 (James Madison Highway) in Woolsey, 3.89 miles north of I-66.

SR 234 (Prince William Parkway) Improvement Projects

The Balls Ford Road Interchange project, part of the Transform I-66 Outside the Beltway initiative, will consist of building a new diverging diamond interchange (DDI) between Prince Williams Parkway (SR 234) and a realigned Balls Ford Road. The DDI will allow for easier access to a new park and ride facility and nearby I-66.¹ Initial construction began Summer 2020 with an anticipated completion set for November 2022.²

Improvements at University Boulevard within Innovation Park industrial complex will construct a new connector road (Discovery Boulevard Extension) in order to eliminate all left turn movements at the intersection. Prince William Parkway (SR 234) will also be widened to six lanes in the vicinity. The project is slated to wrap up by Fall 2022.³

Interchanges will replace at-grade intersections at Route 234 Business (Dumfries Road) and Brentsville Road/Prince William Parkway (SR 294) south of Manassas. Brentsville Road will be realigned to meet Dumfries Road as a part of the project, and Bradley Cemetery Way will serve as a connector route between SR 294 (Prince William Parkway) and SR 234 Business. Construction is scheduled for completion by Summer 2023.⁴
