About the Project
Starting in July 2017, construction began to rebuild the I-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 by July 2020.
This project will relocate the Exit 140 interchange slightly south of the existing interchange. New overpasses will carry Courthouse Road traffic over Interstate 95.
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 I-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 was installed at the entrance to Colonial Forge High School and the Liberty Knolls subdivision before the start of the 2017 - 18 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.
Construction Is Underway
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 overnight.
Drivers should 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.

Work Zone Speed Limit is 35 MPH
The speed limit was reduced to 35 mph on Courthouse Road between Woodcutters Road and Cedar Lane beginning Friday, Aug. 18, 2017.
The speed limit was lowered from 40 mph in the 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.
Traffic Signal Activated At Colonial Forge High School
A temporary traffic signal was activated Wednesday, Aug. 23, 2017, at one of the entrances to Colonial Forge High School and Liberty Knolls Drive. Read more about this signal.
Overnight Ramp Closure March 12-15, 2018
Starting the evening of Monday, March 12, the on-ramp to Interstate 95 southbound from Courthouse Road will be closed for four consecutive nights to allow crews to finish paving and milling work on the temporary ramp.
The existing on-ramp will close overnight Monday, March 12 through Thursday, March 15 from 7:30 p.m. to 4:30 a.m. the following morning.
Traffic will then be shifted onto the new, temporary ramp starting early Friday, March 16.
The on-ramp is the only ramp affected with this work. Traffic can still exit to Courthouse Road from I-95 southbound on these evenings.
This work has been scheduled weather permitting.
The on-ramp will remain open during the day. There will be no impacts to traffic during the morning and afternoon rush hours.
Local traffic should use the most convenient alternate route to access I-95 southbound, including Route 1 to Exit 143/Garrisonville or Exit 136/Centreport Parkway. Detour signs will be placed along the interstate to guide drivers not familiar with the area.

Courthouse Road Park and Ride Lot
This project will relocate and expand the VDOT Park and Ride lot on Courthouse Road in Stafford County.
When construction is complete in 2020, two new Park and Ride lots will open along the relocated Courthouse Road east of I-95. The lots will have a 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 and 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 545 parking spaces will be available during construction.
VDOT asks that carpools, vanpools and transit riders 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 used 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, approved by the Federal Highway Administration, are below.
