About the Project

Interstate 95 Exit 140 Interchange Relocation and Route 630 Widening

The Interstate 95 interchange at Exit 140 (Route 630/Courthouse Road) in Stafford County will be rebuilt as a diverging diamond interchange. 

The interchange will be relocated slightly south of the existing interchange. 

The project will also relocate the intersection of Courthouse Road and Route 1 to the south to align with Hospital Center Boulevard.

Courthouse Road will be widened to four lanes between Route 1 and Interstate 95. West of I-95, Courthouse Road will be widened to four lanes to a point just west of Ramoth Church Road/Winding Creek Road. 

A traffic signal will be installed at the entrance to Colonial Forge High School.
Construction will also realign Ramoth Church Road and Winding Creek Road to intersect at a traffic signal.

The Virginia Department of Transportation will construct this project using the design-build procurement method. A request for proposals will be issued in spring 2016, with a project award expected in fall 2016. For more information, please see VDOT's Alternate Project Delivery page

I-95 Southbound Fourth Lane Construction Option

VDOT has proposed constructing a fourth lane on Interstate 95 southbound as part of this project. It will be included as a bid option when the I-95 Exit 140 interchange and Route 630 widening project is advertised. 

Design and construction of a fourth I-95 travel lane will be contingent on available funding after bids are submitted and reviewed. 

Construction of a fourth southbound I-95 lane is proposed to be built in Stafford between I-95 mile marker 143 and 2,250 feet south of the new, relocated I-95 interchange at Exit 140 (Route 630/Courthouse Road). 

The fourth lane would begin at the end of the southbound exit from the 95 Express Lanes Southern Terminus Extension project. This project will construct an approximate 2.2 miles of reversible extension of the Express Lanes. 

The fourth lane would be open to all traffic in the general purpose lanes of I-95 southbound. 

Construction is anticipated to occur within the existing right-of-way. As part of this project, new sound walls are proposed along the general purpose lanes within VDOT right-of-way.

Diverging Diamond Interchange (DDI)

A diverging diamond interchange (DDI) is an innovative design that is increasingly being built or considered by state transportation departments.

The ramp configuration is similar to a traditional diamond interchange. However, traffic on the cross street, Courthouse Road, will switch sides.

Traffic is shifted to the left side of the road, which allows vehicles turning left to enter an interstate on-ramp without stopping at a traffic signal.
