Issue 33 | February 2022
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 Updates
In January, crews continued construction activities along the corridor:

Area 1 East: Baron Cameron Avenue to Carpers Farm Way:
  • Completed post installation and continued panel installation for the noise barrier along westbound Route 7 between Colvin Run Road (east) and Colvin Run Road (west).
  • Completed panel installation and began backfilling at the retaining wall along westbound Route 7 west of the pedestrian underpass at Colvin Run Mill Park.
  • Continued storm sewer installation for Stage 3A between Baron Cameron Avenue and Colvin Forest Drive.

  • Completed storm sewer installation for Stage 2A east of Baron Cameron Avenue and continued storm sewer installation for Stage 2A west of Baron Cameron Avenue.

  • Continued construction of foundations for the piers and western abutment of the eastbound Route 7 bridge over Difficult Run, including drilled shaft installation for Pier 1 and excavation for Pier 2.

  • Continued earth-moving activities for Stage 3B between Lewinsville Road and Jarrett Valley Drive.
  • Starting drilling for noise barrier foundations along eastbound Route 7 near Serenity Woods Lane.  
  • Continued excavation of the stormwater management pond on the east side of McLean Bible Church. 
  • Completed storm sewer installation for the service road between McLean Bible Church and Laurel Hill Road. 
  • Shifted traffic to Stage 3A between Lyons Street and Lewinsville Road.

Third-party utility design and relocation activities are also ongoing.

Rebar cages in the drilled shafts will support the Difficult Run bridge.
Looking Ahead
The new Lewinsville Road intersection, which will include a displaced left-turn from eastbound Route 7 to Lewinsville Road, is scheduled to open to traffic later in 2022. The initial configuration of the intersection will be a temporary condition, with the permanent condition to be implemented in Fall 2022. The new configuration has been designed to maximize throughput at this busy intersection, and we'll provide detailed navigation information in the upcoming weeks.
