Beginning July 28, lane shifts and traffic patterns will be changing between Utterback Store Road and Reston Avenue.
The Virginia Department of Transportation will be adding a third lane and shared-use paths in each direction, running about seven miles along Route 7.
The department is also adding a pedestrian underpass to access Colvin Run Mill Park, replacing and raising the bridge over Difficult Run and making more bicycle, pedestrian and intersection improvements, according to a statement from the department.
Work shifts will take place during daytime and overnight hours, according to the statement.
Starting on or around August 3, cleaning crews will begin work clearing during the daytime hours. All residences, businesses, and public facilities will still be accessible.
The speed limit on Route 7 will be reduced to 45 miles per hour in active work zones between Reston Avenue and Jarrett Valley Drive.
