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.

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 two weekends in late July and early August. Please see the related traffic alert for details on the July 29-Aug.1 detours. All work is weather-permitting.

Work is ongoing at Lewinsville Road and Brook Road while crews build the new intersection..
