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.

On October 19, 2016, the Commonwealth Transportation Board awarded a $99.9 million design-build contract for this project to Shirley Contracting Company, Inc., of Lorton, Va.

Construction is estimated to begin in summer 2017.

I-95 Southbound Fourth Lane Construction Option

Construction of a fourth lane on Interstate 95 southbound was proposed as part of this project, and was contingent on available funding after bids were submitted and reviewed. 

Funding needed to construct the fourth southbound lane was not secured. This general purpose lane will not be built as part of this project.

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.
