About the Project
Construction is now occurring on this project that involves installing 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 will improve safety and incident management and include new sign gantries, shoulder and lane control signs, speed displays, incident and queue detection, and increased traffic camera coverage.
Drivers are seeing the new overhead sign gantries installed between the Beltway and Route 29 in Centreville.
TransCore is designing and building the active traffic management system.
The project is scheduled for completion in mid-summer 2015.
