About the Project

This project aims to reduce congestion and improve safety by widening Rolling Road (Route 638) from two to four lanes between Viola Street and Old Keene Mill Road.

The project also includes a shared-use path to increase safety for bicyclists and pedestrians.

The project is being planned in a phased approach:

Phase 1 - Old Keene Mill Road intersection improvements
Includes interim improvements by adding a second left turn lane from Rolling Road to westbound Old Keene Mill Road, adding a dedicated right turn lane to eastbound Old Keene Mill Road, upgrading the signal and improving the intersection alignment.  

Phase 2 -  Widening and other improvements 
Includes widening Rolling Road from two to four lanes between Viola Street and Old Keene Mill Road, signal upgrades, pedestrian and bike facilities and improvements to access management.  

The project team has worked with Fairfax County to consider alternative design options, including the possibility of using underground utilities.

The option including underground utilities was evaluated based on feasibility, potential property impacts, cost and schedule. This option is no longer being pursued due to cost concerns.

If you would like to provide feedback at any time, send comments to Include “Rolling Road Widening” in the subject line.

This project is being financed with federal, state and local funding including Northern Virginia Transportation Authority funds.
