Note: Rolling Road widening preliminary traffic management plans have been posted below under "Resources." 

Old Keene Mill Road Intersection Improvements

Plans include:

  • Adding a second left turn lane from Rolling Road (Route 638) to westbound Old Keene Mill Road (Route 644)
  • Adding a dedicated right turn lane to eastbound Old Keene Mill Road
  • Upgrading the traffic signal 
  • Improving the intersection alignment

Rolling Road Widening 

Plans include:

  • Widening Rolling Road from two to four lanes between Viola Street and Old Keene Mill Road
  • Traffic signal upgrades 
  • A shared-use path for bicyclists and pedestrians
  • Access management improvements 

The project team has worked with Fairfax County to consider alternative design options, including the possibility of undergrounding utilities. This option was evaluated based on feasibility, potential property impacts, cost and schedule. This is no longer being pursued due to cost.

Estimated Costs
Preliminary Engineering: $7.2 million
Right of Way Acquisition and Utility Relocation: $23.3 million
Construction: $48.4 million
Total: $78.9 million

This project is financed with federal, state, county and Northern Virginia Transportation Authority funds.
