Route 690 Corridor Study


  • Loudoun County is conducting a study to proactively examine travel conditions and analyze current and future traffic volumes along Hillsboro Road (Route 690). The study will evaluate the potential increase in traffic along the corridor with the opening of the Route 690 and Route 7 interchange. Construction of the interchange is estimated to be completed by 2027.  
  • There are multiple planned roadway network improvements in northwest Loudoun County west of Leesburg that will impact north-south traffic patterns along Hillsboro Road (Route 690) between Charles Town Pike (Route 9) and Route 7.  
  • The study will also evaluate recent crash history and field observations of driver behavior and roadway conditions. 
  • The study’s recommendations will identify any operational or safety improvements that would be needed to accommodate the changes in future travel patterns on Route 690.
