Route 15/17/29 Interchange, Fauquier County
|Construction of grade-separated interchange at Rt. 29 Business and Rt. 880 (Lord Fairfax Dr.)|
Project at a Glance
Estimated $28.34 million
Lengths and Limits
From 1.05 miles south to 1.05 miles north of Route 29 Business
The purpose of this project is to replace the existing at-grade intersection of Route 15/17/29, Route 29 Business and Route 880 (Lord Fairfax Drive) with a grade-separated interchange to improve safety and capacity.
An interchange was envisioned at this location when the Warrenton Bypass was constructed in the 1980s and was included in the Six-Year Improvement Program in 2012. The project will provide improved traffic flow due to an increase of traffic through this intersection for commuters as well as those traveling to the Fauquier County landfill and Lord Fairfax Community College.
Route 15/17/29 currently carries approximately 43,500 vehicles each day, a number that is projected to increase to 74,000 by 2040.
On March 26, 2015, VDOT issued notice to proceed to its preliminary engineering and design consultant Volkert, Inc.
Over the next several months, Volkert’s work will include collection of traffic data; observation of bicycle and pedestrian activity in the area, current traffic signal operation and related traffic backups; and other field assessments.
This data will be used to analyze the operation of the various design concepts being considered, including:
- A “no-build” alternative that would leave the intersection as-is
- Grade-separated diamond interchange that incorporates roundabouts
- Grade-separated “tight diamond” interchange
- Grade-separated “urban diamond” interchange
- A cost-effective, innovative option to be developed and presented by the consultant
Other factors that Volkert will investigate and analyze include safety, planning, geometric feasibility and environmental impacts of the five alternatives above.
Volkert’s findings will be considered by VDOT and presented at a citizen information meeting in the fall.
This project will be scored under the new prioritization process as originally defined in what is known as House Bill 2, signed into law July 1, 2014. In preparation for scoring, much of the project’s funding was removed in the revision of the FY 2015-2020 Six-Year Improvement Program, leaving a balance of $930,540 in preliminary engineering funds.

VDOT estimates costs for this project as follows:
Total Cost: $28,341,148
Design and Engineering: $2,000,000
Right of Way Acquisition and Utility Relocation: $100,000
This project is financed using federal funds. Costs are preliminary planning estimates and subject to change as the project develops. Cost estimates will be updated as the project progresses.
