Route 15 North-Montresor Road to Maryland State Line

Update: July 5, 2022

At its regularly scheduled business meeting on July 5, 2022, the Loudoun County Board of Supervisors approved the Comprehensive Plan Amendment (CPAM) related to safety and operational improvements to U.S. Route 15 north of Leesburg.  

With this approval, the Loudoun County 2019 Countywide Transportation Plan will be amended by changing the planned ultimate condition of U.S. Route 15 between Montresor Road and the Maryland state line.

The proposed improvements of this CPAM include:

  • Widening of U.S. Route 15 to four lanes between Montresor Road and the Village of Lucketts.
  • The installation of a median divide on U.S. Route 15 from Stumptown Road north to Saint Clair Lane.
  • Construction of a bypass around the Village of Lucketts to the west of existing U.S. Route 15. Final location and alignment of the bypass will be determined during the roadway design process.

Additionally, the Board of Supervisors directed county staff to identify safety and operational improvements to the U.S. Route 15 corridor that could be made in advance of the ultimate improvements authorized by the CPAM to improve corridor safety and reliability as soon as possible. A prioritized list of potential improvements to include the estimated costs and time frames to complete each improvement is scheduled to be presented to the Board for consideration no later than its October 18, 2022, meeting.

May Public Hearing

At the Board’s May 11 public hearing, members of the public provided their input on the proposed congestion relief and safety improvements for voiced their concerns regarding Route 15,  safety, as well as their perspectives on possible locations of the proposed Lucketts bypass. 


The segment of US Route 15 between Montresor Road (VA Route 661) and the Maryland state line is classified in the 2019 Countywide Transportation Plan (CTP) as a primary Arterial roadway and is part of the Journey Through Hallowed Ground National Scenic Byway.

In 2016, the Loudoun County initiated a Route 15 Congestion Study to identify the cause of recurring congestion on US Route 15 north of Leesburg, especially in the northbound direction during the afternoon and evening peak periods.  The Route 15 Congestion Report Findings were presented to the Board of Supervisors at the May 18, 2017 Business Meeting. The report concluded that additional capacity was needed along the corridor. At the Board’s direction, the report was then expanded to include a Safety and Operations Analysis of Route 15 from Whites Ferry Road to the Maryland state line. 

On March 6, 2018, a Comprehensive Plan Amendment (CPAM-2017-0002) was approved to amend the 2010 CTP to revise the planned ultimate condition of the segment of US Route 15 between North King Street and Montresor Road from a two-lane local access undivided rural arterial roadway to a four-lane median divided roadway.
