Under Construction: Rippon Boulevard and Blackburn Road Traffic Signal in Prince William County

Cost and schedule ►

Public outreach ►

The project is installing a new traffic signal at the intersection of Rippon Boulevard and Blackburn Road. Based on VDOT's traffic study, existing congestion and crash history at this location warrant installing a traffic signal.

The project also includes:

  • Restoring the turn lanes on Rippon Boulevard that have not been in use since the intersection became a four-way stop
  • Flashing yellow arrows for left turns from Rippon Boulevard.
  • Additional sidewalk connections from Blackburn Road to the shared-use path along Rippon Boulevard
  • Accesible Pedestrian Signals

At the intersection, Rippon Boulevard averages 11,000 vehicles a day and Blackburn Road averages up to 6,800.

Estimated Costs
Preliminary Engineering - $445,000
Right of Way Acquisition and Utility Relocation - $40,000
Construction: $639,000
Total: $1.1 million

This project is financed with federal and county funding.


This project aims to improve driver and pedestrian safety as well as operations at the intersection.
