Lorton Road / Silverbrook Road Improvements

Intersection and corridor improvements focused on congestion, safety, turning movements, and multimodal access in the Lorton / Laurel Hill area.

Quick Summary

The Lorton Road / Silverbrook Road corridor is one of the most important local transportation nodes in South Fairfax. It serves commuters, school traffic, neighborhood trips, transit access, and regional traffic moving between Lorton, Laurel Hill, Silverbrook Road, Route 123, and I-95.

Ongoing transportation review has focused on improving traffic operations, turn-lane performance, pedestrian and bicycle safety, and coordination with nearby projects.

Project Type

  • Roadway and intersection operations
  • Traffic engineering review
  • Safety and congestion mitigation
  • Multimodal corridor coordination

Location

Lorton Road and Silverbrook Road intersection and surrounding corridor, including nearby connections to Laurel Hill, Lorton, Hooes Road, Route 123, and I-95.

Lead Agencies

  • Fairfax County Department of Transportation
  • Virginia Department of Transportation
  • Fairfax County land use and planning coordination
  • Office of the Mt. Vernon and Springfield District Supervisors

Purpose & Need

The corridor experiences recurring congestion, turning delays, queueing, and safety concerns during peak travel periods. The area also serves residents accessing schools, parks, neighborhoods, transit, and regional roadway connections.

The purpose of the ongoing review is to identify improvements that can support safer and more reliable movement for drivers, pedestrians, bicyclists, transit riders, and nearby communities.

Project Description

Potential improvements may include operational changes, turn-lane modifications, signal timing review, pedestrian crossing improvements, bicycle and sidewalk coordination, and corridor-level traffic management.

Because multiple transportation and utility projects affect the broader area, coordination is important to avoid overlapping disruptions and to ensure improvements work together.

Current Status

🟡 Active Study / Traffic Engineering Review

Fairfax County and VDOT continue evaluating corridor conditions and potential operational improvements. Future implementation will depend on final engineering recommendations, funding availability, agency coordination, and community review.

Community Impacts / Considerations

  • Peak-period congestion and turning delays
  • Queueing near key intersection approaches
  • School, commuter, and neighborhood traffic overlap
  • Pedestrian and bicycle crossing needs
  • Coordination with rail, utility, and active transportation projects nearby

Related Projects

Next Steps

  • Continue traffic analysis and engineering review
  • Coordinate with VDOT and Fairfax County project teams
  • Monitor interaction with nearby construction and utility work
  • Identify funding and implementation options
  • Provide community updates as recommendations advance
