I-66 “Active Traffic Management System” goes online Wednesday

The Virginia Department of Transportation will bring the new I-66 Active Traffic Management System (ATMS) online Wednesday, September 16 at noon. The system will be implemented between the District of Columbia and Route 29 in Gainesville.

VDOT says the system “allow for improved safety and incident management along one of the most congested interstate highways in Virginia and the nation.”

ATMS components include:

·         Expanded use of the shoulder lanes between the Beltway and Route 50 – The shoulder lanes, also known as the red ‘X’ lanes, will routinely be opened to traffic when congestion builds, regardless of the time of day or day of the week. Currently, the shoulder lanes are used only during weekday peak periods.

·         New lane control signals (pictured above) on all lanes between Nutley Street and Route 29 in Centreville – Motorists will be able to see which lanes are usable or blocked well in advance of incidents

·         Expanded camera and dynamic message sign coverage between the District of Columbia and Route 29 in Gainesville – The cameras will improve monitoring of the highway and thus enable transportation, safety and law enforcement personnel to respond more quickly and appropriately to incidents. The dynamic message signs will advise drivers on incidents and delays.

·         Upgrades to the ramp metering system inside the Beltway – The ramp meters that help manage traffic merging onto I-66 will be able to adapt to traffic conditions.

Lane control signals between Nutley Street and the Beltway will be completed in the next few weeks.

Motorists are asked to be alert and follow the new signage accordingly.

The $38.6 million ATMS was designed and is being constructed by TransCore. The project is expected to be completed under budget.
