Issue 13 | June 2020
Along about seven miles of Route 7, we're adding a third lane and shared-use paths in each direction, building a pedestrian underpass to access Colvin Run Mill Park , replacing and raising the bridge over Difficult Run, and making many intersection, bicycle and pedestrian improvements. Learn more.
Construction and Design Updates
In May, crews continued construction activities along the corridor, including:

  • Difficult Run/Colvin Run area: Continued relocation of communication utilities.
  • Storm sewer installation between Utterback Store Road and Baron Cameron Avenue continued.
  • Relocated communications lines between Reston Parkway and Markell Court.  
  • Began clearing and earth-moving for a stormwater management pond along westbound Route 7 near Trotting Horse Lane.
  • Continued earth-moving and grading between Reston Avenue and Reston Parkway.  
  • Performed cement stabilization of the subgrade, placed concrete-treated aggregate, installed underdrain, and placed based asphalt for future eastbound lanes between Reston Parkway and Bishopsgate Way, and between Baron Cameron Avenue and Delta Glen Court.  
  • Placed temporary asphalt in the Route 7 median between Faulkner Drive and Towlston Road in preparation for lane shifts.  
  • Strengthened shoulders along westbound Route 7 between Faulkner Drive and Towlston Road.
  • Started earth-moving operations between McLean Bible Church and Jarrett Valley Drive.  

Design work continues for lighting and landscaping. Third-party utility design is also ongoing.

Work Continues in the Colvin Run and Difficult Run Area
As part of the improvements along Route 7, we'll be replacing and raising the Difficult Run bridge and shifting Colvin Run to the south to accommodate the third lane on eastbound Route 7. Construction activities in the Colvin Run and Difficult Run area and along Carpers Farm Way will be ongoing, with new work scheduled to begin in late June/early July. Crews will be working within the VDOT right of way and where rights have been acquired from property owners.

The work is being done under the permits from the U.S. Army Corps of Engineers , the Virginia Marine Resources Commission, and the Virginia Department of Environmental Quality . Erosion and sediment (E & S) controls will be in place and wetland areas will be clearly delineated. The project's Environmental Compliance Specialist monitors E & S controls daily, with project-wide inspections occurring twice weekly.

In Case You Missed It
Starting on or about Friday, June 26, drivers can expect lane shifts on eastbound Route 7, temporary traffic pattern changes, and detours on some neighborhood streets between Baron Cameron Avenue and Carpers Farm Way. Work will occur during the daytime and overnight hours. All homes, businesses, and public facilities will remain accessible via posted detour routes. Click here for details.

Drivers will experience a new traffic pattern at the east entrance to McLean Bible Church starting on or about Monday, June 29. Click here for details.

Additional lane shifts and traffic pattern changes will take place in July. We'll send out a traffic alert with detailed information prior to the changes.
