RICHMOND, Va. (WUSA9) -- Virginia Governor Bob McDonnell says the Virginia Department of Transportation will create an active traffic management system for Interstate 66 from Washington, D.C. to Gainesville, Va. 

According to a press release from the governor's office, VDOT will begin building the $34 million system this spring. Officials hope to have it completed by early 2015.

The system will include "dynamic message and lane control signs" to notify drivers of incidents and delays, travel times and give directions on merging traffic on 34 miles of I-66, according to the governor's office. Officials also expect improved road monitoring and information to help emergency crews to clear crashes and other incidents more quickly.

According to Secretary of Transportation Sean T. Connaughton in the press release on Tuesday, "The ATM system will continuously monitor traffic and road conditions using technology such as vehicle-detection sensors and closed-circuit television cameras."

Tools to help with traffic flow and safety include "advanced lane-control signals, queue warning, dynamic use of shoulder lanes, adaptive ramp metering and speed harmonization strategies," according to the press release.

According to officials, construction will begin with six emergency pull-off areas inside and outside the Capital Beltway. Then VDOT will add other features such as dynamic message signs, ramp meters, sensors and new traffic cameras. Crews will place gantries every half-mile with lane-control signals and queue warning systems from I-495 to Route 29 in Centreville, say officials.

VDOT is using technology and lessons from ATM projects in Europe and Seattle, according to the press release. The design-build contract was awarded to TransCore.
