Route 15 North Widening: Battlefield Pkwy. to Montresor Rd.


  • This project includes the design, land acquisition and construction to widen Route 15 from two to four lanes between Battlefield Parkway and Montresor Road. The project scope includes: 
    • a signalized Continuous Green "T" (CGT) intersection at North King Street to allow through traffic to continue north on Route 15 without stopping
    • an updated signalized intersection at Whites Ferry Road
    • a two-lane hybrid roundabout at Montresor Road
    • a realigned section of Limestone School Road to connect with the Montresor Road roundabout
    • a shared use path on the west side of Route 15 from Tuscarora High School to Montresor Road
    • a shared use path along the entire length of Whites Ferry Road
  • The design process includes context-sensitive methods and follows the Journey Through Hallowed Ground guidelines where possible.
  • The results of the Route 15 North Congestion Report, initiated to reduce traffic between Battlefield Parkway and Whites Ferry Road, were presented to the Board of Supervisors in May 2017.
    • Recommendations from the report included widening Route 15 from two to four lanes between Battlefield Parkway and Montresor Road.
    • As a result of the report, the board directed the initiation of the Route 15 North Safety and Operations Study to identify potential improvements between Whites Ferry Road and the Maryland state line. 
  • Public workshops and focus group meetings were held between August 2017 and October 2018 to obtain public feedback on Route 15 North widening design alternatives and evaluate traffic data and proposed concepts for the Route 15 North Safety and Operations Study. 
  • The project is based on congestion, safety and operational studies that were performed between 2016 and 2018, endorsed by the Board of Supervisors on May 18, 2017 and expanded by the Board on September 20, 2018.

Current Status: August 2021

  • During the months of August, September and October 2021, Loudoun County will be periodically closing a lane along James Monroe Highway (Route 15) between Battlefield Parkway and Montresor Road for the purpose of soils testing and investigations.

Exhibit materials showing updates to the March 2020 30% design and a question and answer document are available in the Document section below.
  • In March 2020, J2 Engineers, Inc. updated the initial concept design and developed 30% design exhibits showing the draft roadway alignment.
  • A phase I environmental site assessment was completed in March 2020.
