About the Project

Work began in April 2013 to construct auxiliary lanes and widen the shoulders on a seven-mile stretch of Interstate 95 in Prince William County. The project was designed to ease several chokepoints, add capacity during emergencies, and reduce weaving and merging.

The inside and outside shoulders between Dumfries Road and the Prince William Parkway were widened, both north and southbound, to 12 feet with full-depth pavement to make the shoulders suitable for traffic use during accidents, evacuation, enforcement and detours. New guardrail and lighting were added.

Auxiliary lanes were constructed at three locations to create safer access and merging, particularly at the truck scale area. To create the auxiliary lane, crews extended the acceleration and deceleration lanes between on- and off-ramps.

On I-95 North, auxiliary lanes now connect the Opitz Boulevard on-ramp with the Prince William Parkway off-ramp, as well as the Route 234 on-ramp with the truck weigh station off-ramp. 

On I-95 South, an auxiliary lane now connects the truck rest area on-ramp with the off-ramp to Route 234.
