Project Status

On Feb. 21, the Commonwealth Transportation Board awarded a $19.6 million contract to Shirley Contracting Company, LLC of Lorton to construct the Warrenton Interchange Project. 

Construction is anticipated to begin this fall. 

Project Purpose

The purpose of this project is to replace the existing at-grade intersection of Route 15/17/29, Route 15/17/29 Business and Route 880 (Lord Fairfax Drive) with a grade-separated interchange to improve safety and capacity. Traffic conditions at this location include a high volume of northbound left turns into the town of Warrenton, a large (12 percent) volume of truck traffic, and local traffic associated with Lord Fairfax Community College, the Fauquier County landfill and homes nearby.

An interchange was envisioned at this location during the design of the Eastern Bypass in the 1970s. A “T” intersection was initially constructed with the Eastern Bypass and improvements were made in the 1990s, resulting in the existing four-leg signalized configuration. Funding for an interchange design was programmed in 2006 and concepts were developed in the following years. Fauquier County applied for the remainder of funding through the House Bill 2 prioritization process, now known as Smart Scale, which was awarded in June 2016.

The Eastern Bypass currently carries approximately 43,500 vehicles each day. Traffic counts on Route 15/17/29 Business and Lord Fairfax Drive are 11,000 and 2,000 vehicles per day, respectively.

What Is Proposed?

This project will replace the existing intersection of Route 15/17/29 (Eastern Bypass), Route 15/17/29 Business and Route 880 (Lord Fairfax Drive) with a grade separated interchange for improved safety and traffic flow.  

The interchange design, which is subject to change, will remove the existing traffic signal on the Eastern Bypass, allowing free flow of through traffic. Motorists on the Eastern Bypass will use ramps to access Route 15/17/29 Business and Lord Fairfax Drive, which will cross the Eastern Bypass on a new overpass bridge with roundabouts at each end.

During construction, traffic will be maintained through the use of detours and reduced work zone speed limits will be in effect.  Access to all properties will be maintained.
