Construction is Underway!
Construction began on July 10, 2017 to widen Courthouse Road in Stafford County to four lanes west of Interstate 95. The road will be widened between Ramoth Church Road and Cedar Lane.
During construction, drivers can expect lanes to stay open on Courthouse Road during morning and evening rush hour to minimize delays at peak travel times.
Single lane closures will be scheduled at midday and during overnight hours.
As drivers adjust to the work zone, consider adding several minutes of travel time when leaving for work or school.
Travelers can expect to see construction equipment and signs, temporary lane markings, and traffic shifts.

New Speed Limit Posted in the Work Zone Starting Friday, August 18, 2017
The speed limit will be reduced to 35 mph on Courthouse Road between Woodcutters Road and Cedar Lane beginning Friday, August 18, 2017.
The speed limit is being lowered from 40 mph to 35 mph in the construction work zone to widen the road from two lanes to four lanes.
The temporary speed limit will be enforced during construction, which is expected to be complete by July 2020.

About the Project
Starting in fall 2017, construction will begin to build the Interstate 95 interchange at Exit 140 (Route 630/Courthouse Road) in Stafford County as a diverging diamond interchange.
Drivers will continue to use the existing Exit 140 interchange until the end of construction in July 2020.
This project will relocate the Exit 140 interchange 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.

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.
A traffic analysis, in the form of an Interchange Modification Report, has been performed on the Diverging Diamond Interchange concept. The findings have been approved by the Federal Highway Administration and can be found below.
