About the Project

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.

Construction Schedule

Tentative construction dates have been scheduled for this project. Final schedule information will be available at public meetings before construction begins in summer 2017.

Winter-Spring 2017: Final survey and geotechnical work.

Spring 2017: Right of way acquisition begins for properties affected by the Exit 140 interchange project.

Summer 2017: Construction begins on the Courthouse Road widening project.

Winter-Spring 2018: Construction begins on Exit 140 interchange and new Park & Ride lot.

Late 2019: Completion of Courthouse Road widening.

July 31, 2020: Construction complete on entire project, with the diverging diamond interchange open to traffic. The contractor has a financial incentive to finish work by May 2, 2020.

Courthouse Road Park & Ride Lot

This project will relocate and expand the Virginia Department of Transportation Park & Ride lot on Courthouse Road in Stafford County.

The existing number of spaces in the lot – 545 parking spaces – will always be available during construction in the vicinity of Exit 140. The contractor is required to provide a minimum of 545 parking spaces at all times in a temporary location while construction is underway. VDOT wants carpools, vanpools and transit riders to continue ridesharing from this Interstate 95 interchange during construction.

The new, permanent Park & Ride lot will be moved east of I-95 and expanded to approximately 1,000 spaces.

A precise schedule for Park & Ride lot impacts has not been set. As soon as these dates are available, we will communicate with lot users and the community regarding a move to a temporary Park & Ride lot. Commuters can expect to have 545 spaces available throughout construction.

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.
