• 3-mile widening from Gainesville to Haymarket
• Adding two lanes, one (HOV) high occupancy vehicle and one regular, in each direction
• $73.5 million project will be complete Aug. 2016
• Expect lane closures Sunday nights thru Thursday nights

PRINCE WILLIAM COUNTY — The Virginia Department of Transportation (VDOT) begins work next week to widen Interstate 66 from Route 29 at Gainesville to Route 15 at Haymarket. When completed in August 2016, motorists will have three regular and one HOV lane in each direction.

The project will improve traffic flow to and from Haymarket, western Prince William and eastern Fauquier counties and provide a continuous stretch of three regular lanes and one HOV lanes in each direction for 25 miles, from I-495 to Route 15.    

The first improvement will be adding a left turn lane on the westbound I-66 ramp to Route 15 where traffic backs up during the evening rush.  That work begins April 7 and will be complete by the end of June. Motorists can expect a left shoulder closure and occasional off-peak lane closures.

On or about April 13 and for the next two months, crews will mill and pave I-66, first westbound and then eastbound, in preparation for a traffic shift. Motorist can expect nighttime lane closures for this work.

The widening project also includes:

• Reconstruction of two overpasses at Catharpin Road and Old Carolina Road/S. Jefferson Street to include a ten-foot shared-use path on each bridge
• Intelligent Transportation Systems (ITS) components for managing traffic volumes, improving flow and enhanced incident response
• Overhead sign structures
• Utility relocations
• Storm drainage and storm water management facilities
• Retaining walls, sound barriers and roadway lighting on the two overpasses
• 12-foot paved shoulders
