Issue 37 | June 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 May, crews continued construction activities along the corridor:

Area 1: Reston Avenue to Colvin Forest Drive (Except Baron Cameron Avenue Intersection)

The concrete segments for the north half of the pedestrian underpass at Colvin Run Mill Park were installed. The structure above the underpass supports the underground utilities through the area during construction.

Concrete is placed on new eastbound Route 7 bridge over Difficult Run.

Looking Ahead

In preparation for the upcoming opening of the new intersection at Lewinsville Road, including a displaced left-turn from eastbound Route 7 to Lewinsville Road, temporary detours will be in place over several weekends in July and August.

Traffic alerts will be sent out to the community and posted on the project website in advance of the detours.

In Case You Missed It

Construction activities along Route 7 will continue in 2022, and additional traffic shifts and temporary detours will occur along Route 7 during the summer months. Please see the project website for information on upcoming lane shifts and other roadway impacts.
