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 sign gantries, shoulder and lane control signs, speed displays, incident and queue detection, and increased traffic camera coverage.
Overhead sign gantries were installed between the Beltway and Route 29 in Centreville.
TransCore designed and is building the active traffic management system.
The project is scheduled for completion in the winter of 2016.
