The interchange opening is a major milestone in the $195 million project to expand capacity and improve travel in Stafford County’s Courthouse Road area.

Diverging Diamond Interchanges (DDIs) lower the number of conflict points between vehicles by eliminating left turns. The new interchange briefly shifts vehicles on Courthouse Road to the other side of the road on new overpass bridges, which allows drivers to merge left onto the I-95 northbound and southbound ramps without stopping at a traffic signal.

On Saturday, Dec. 7, crews will open the new interchange to traffic, with assistance from Virginia State Police and local law enforcement. Opening the interchange early Saturday will allow crews to take advantage of lighter traffic volumes.

In addition to the interchange opening on Dec. 7, motorists can expect:

On eastbound Courthouse Road, all three travel lanes will open in the diverging diamond interchange
At Route 1, a new four-lane Hospital Center Boulevard extension will open west of Route 1 and connect directly to the diverging diamond interchange on Courthouse Road through a new Wyche Road intersection
On westbound Courthouse Road, all three travel lanes will open in the diverging diamond interchange, but the road will narrow to two westbound travel lanes just before Austin Ridge Drive
Courthouse Road west of Austin Ridge Drive will remain reduced to one lane in each direction until late December 2019, when all four lanes will open between the I-95 interchange and Ramoth Church Road/Winding Creek Road
I-95 Southbound Exit Ramp Detour

On December 7, three of the new Exit 140 interchange ramps will open, but the I-95 southbound exit ramp to Courthouse Road will remain in a detour pattern until late December 2019.

Motorists traveling from I-95 southbound to Courthouse Road should follow the posted detour signs to access the new Courthouse Road.

Traffic will be detoured for several weeks to allow crews to build the new exit ramp and raise its elevation to match the height of the new diverging diamond interchange and I-95 overpass bridges. Courthouse Road traffic is currently traveling in the location where this construction work must occur, once the ramp is detoured on December 7.

What Motorists Can Expect

Message boards will be posted beginning the week of December 2 on I-95, Route 1, Courthouse Road and other connecting roads to alert travelers to the Dec. 7 interchange opening.

Numerous signs and pavement markings will guide drivers through the diverging diamond interchange. Watch a simulation video here to experience a traveler’s windshield view and an aerial view.

All work has been scheduled weather permitting. For real-time updates on lane closures and the opening of the diverging diamond interchange:

Project Background

Construction on the Exit 140 interchange and Courthouse Road widening project began in July 2017. All work will be finished by July 31, 2020.

After the new four-lane portion of Courthouse Road opens to traffic west of Austin Ridge Drive in late December 2019, construction crews will focus on finishing the following project elements in 2020:

Expanded Park & Ride commuter parking at Exit 140: New Park & Ride lots are under construction north and south of the future Old Courthouse Road. Together, the lots will offer around 1,100 parking spaces. The southern lot will have a dedicated pickup and dropoff area for buses, carpools, and vanpools.
New sidewalk and shared use path: Crews will continue building new sidewalk from the Park & Ride lots east along Old Courthouse Road to the Stafford County Government Center, and a shared use path from Austin Ridge Drive to the Park & Ride lots through the interchange. A new, shared use path from Winding Creek Elementary School near the Ramoth Church Road/Winding Creek Road intersection to west of Austin Ridge Drive will open on Dec. 7.
Courthouse Road carries an average of 16,000 vehicles a day and around 136,000 vehicles a day travel on I-95 near Exit 140.
