Eastern Loudoun Transportation Study
link to interactive status mapIn 2012, the Loudoun County Board of Supervisors directed
staff to undertake a study of the road network in Eastern Loudoun, which was defined as the area east of Route 659 and Route 659 relocated from the Potomac River on the north, Prince William County to the south and Fairfax County to the east.

The purpose of the study was to provide information relating to the Countywide Transportation Plan (CTP) road network to include: 
  • Network deficiencies; 
  • Missing links; 
  • Cost estimates to build the interim condition; 
  • Development proffers/conditions related to the missing links and network deficiencies; 
  • The proffer/condition triggers; 
  • Right of way availability; and 
  • Potential funding sources if the projects are not funded wholly or in part through proffers/conditions.

On March 7, 2012, staff presented a report that reviewed recent and ongoing efforts to address network deficiencies and missing links in the CTP road network; provided an existing conditions inventory of the deficiencies and missing links (103 road segments); provided a cost estimate to build out the CTP road network to the interim condition; and offered a funding outlook of non-proffer funding sources.

The study area was divided into three phases: 

Phase 1 efforts have been completed. Staff's report to the Board of Supervisors on November 7, 2012, is online here.
Phase 2 efforts have been completed. Staff's report to the Board of Supervisors on April 3, 2013, is online here.
Phase 3 efforts have been completed. Staff's report to the Board of Supervisors on January 15, 2014, is online here. The report's attachments are here.

The Eastern Loudoun Transportation Study Map was updated in June 2014 to identify road segments that have been completed, roads projects that are in progress, and roads that are funded in the Adopted FY 2015 – FY 2020 Capital Improvement Plan. The updated map is online here.new

Interactive Map: Eastern Loudoun Transportation Study Status Map

An interactive map illustrating the status of the Eastern Loudoun Transportation Study includes links to a proffer analysis for each of the 26 road segments in the Phase 1 study area. Each report includes the segment name, segment location, the category of improvement needed, the estimated cost, funding options, a location map and analysis of the applicable proffers/conditions tied to the specific road segment.


As the Board identifies priority road projects, staff will continue to review the cash proffer/condition funds to determine eligibility to use on the identified projects.
