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 just west of Ramoth Church Road/Winding Creek Road. 

A temporary traffic signal and pedestrian crossing will be installed at the entrance to Colonial Forge High School and Liberty Knolls subdivision before the start of the 2017-2018 school year. A permanent traffic signal will be installed at the end of the project.

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 will begin in summer 2017.

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.

When construction is complete in 2020, two new Park & Ride lots will open along the relocated Courthouse Road east of Interstate 95. The lots will have a combined total of 1,100 parking spaces.

A lot north of Courthouse Road will have approximately 850 parking spaces, and will include a dedicated carpool/vanpool pickup and dropoff area to assist with High Occupancy Vehicle (HOV) use. This lot will also have a dedicated bus dropoff and pickup area.A smaller lot south of Courthouse Road will have an additional 250 parking spaces.

Current lot users will see no change until summer 2018. The existing Park & Ride lot will remain open until that time.

In summer 2018, the existing lot will be closed, and users will be shifted to a temporary lot east of I-95. The existing number of spaces in the lot – 545 parking spaces – will always be available during construction. VDOT wants carpools, vanpools and transit riders to continue ridesharing from this I-95 interchange during 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.
