About the Project

This project installed an active traffic management (ATM) system on I-66 through Arlington, Fairfax and Prince William counties from the Washington, D.C. line to Route 29 in Gainesville. The system has improved safety and incident management and includes new overhead sign gantries, shoulder and lane control signs, speed displays, incident and queue detection, and increased traffic camera coverage.

The overhead gantries were installed between the Beltway and Route 29 in Centreville.

TransCore designed and built the active traffic management system, which was activated in September 2015.

The project is scheduled for final completion in the spring of 2016.
