Issue 41 | October 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.

The third through-lane on eastbound Route 7  between Reston Avenue and Riva Ridge Drive opened to traffic in September.

In Case You Missed It

The new Lewinsville Road intersection has opened in an interim configuration. Additional improvements are ongoing in this area, including a longer turn lane from eastbound Route 7 to Lewinsville Road, and a longer acceleration lane from Lewinsville Road to westbound Route 7.

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