About the Projects

Exit 140 Diverging Diamond Interchange And Courthouse Road Widening

About the Project

Construction began in July 2017 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. A traffic signal at this intersection is anticipated to be installed in spring 2019.

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.

Travelers can expect to see construction equipment and signs, temporary lane markings and traffic shifts.

Lane Closures for Sunday, December 16 - Friday, December 21

I-95 Southbound

(New) Sunday, 10 p.m. – 4:30 a.m. I-95 southbound will be reduced to a single lane near the interchange for a mobile operation to improve pavement markings. Delays are possible.

(New) Monday, 5 a.m. – 9:30 a.m. A single lane on I-95 southbound will be closed near Exit 140 to allow crews to take soil samples for a future overhead sign foundation. 

I-95 Northbound

(New) Monday, 9:30 a.m. – 3:30 p.m.  A single lane on I-95 northbound will be closed near Exit 140 to allow crews to take soil samples for a future overhead sign foundation.

(New) Monday, 9 p.m. – 4:30 a.m.  A single lane on I-95 northbound will be closed for beam placement for a new interstate ramp.

(New) Tuesday – Thursday, 9:30 a.m. – 3:30 p.m.  A single lane on I-95 northbound will be closed near Exit 140 to allow crews to remove temporary concrete barrier. 

I-95 Northbound FULL RAMP STOPS, Courthouse Road and Austin Ridge Drive FULL TRAFFIC STOPS

(New) Monday, 10 p.m. – 4:30 a.m. Tuesday, ALL traffic on the I-95 northbound on- and off-ramps at Exit 140 will be intermittently stopped overnight for up to 30 minutes at a time starting at 10 p.m. and will be completed by 4:30 a.m. Tuesday. Additionally, all Courthouse Road and Austin Ridge Drive traffic will be stopped at the interchange during beam placement. The full stops are needed to allow crews to safely lift beams into place for a new interstate ramp. All I-95 southbound travel lanes will remain open during this work zone. Message boards on Courthouse Road are posted to provide advance notice of the work zone and possible delays. Virginia State Police will assist with traffic control at the interchange.

I-95 Southbound Off-Ramp

Monday – Thursday, 8 a.m. – 3 p.m. and Friday, 8 a.m. – 12 p.m.  Expect a narrowing of the off-ramp from I-95 southbound to Courthouse Road for construction activities.

Courthouse Road Widening Work:

Monday – Thursday, 9 a.m. – 2:30 p.m. and Friday, 9 a.m. – 12 p.m. Expect brief delays with alternating, one-way traffic at the following locations:

A flagging crew will direct drivers in each work zone.

A full list of weekly lane closures for VDOT's Fredericksburg District (which includes Stafford County) is available at www.VirginiaDOT.org. The list is posted Friday afternoons for the upcoming week.

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, August 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.

Construction Schedule

July 10, 2017: Construction begins on the Courthouse Road widening project west of I-95.

Fall 2017: Construction begins on Exit 140 interchange and Courthouse Road widening east of I-95.

"Pardon Our Dust" Public Information Meeting: Wednesday, May 17, 2017

A "Pardon Our Dust" public information meeting was held from 6 - 8 p.m. at Colonial Forge High School on Wednesday, May 17, to share details on upcoming construction.

Additional public meetings will be held throughout the project to keep residents informed on our progress.

If you would like to schedule a VDOT speaker to visit your community group to speak about this project, contact VDOT Communications Manager Kelly Hannon at Kelly.Hannon@VDOT.Virginia.Gov. or 540-374-3344.

Courthouse Road Park and Ride Lot

This project will relocate the VDOT Park and Ride lot on Courthouse Road in Stafford County.

When construction is complete, two new Park and Ride lots will open east of I-95. The lots will have a total of approximately 1,100 parking spaces.

Both Park & Ride lots will be north of the relocated Courthouse Road, on the future Old Courthouse Road (the Courthouse Road currently in use during construction).

The larger lot 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 on the north side of Old Courthouse Road will have an additional, estimated 250 parking spaces.

During July 2018, the existing Park & Ride lot was closed, and users were shifted to a temporary lot east of I-95 in the same location as the future, permanent lots. The existing 545 parking spaces will be available during construction as the contractor continues work to finish building the permanent lots.

Both parking lots are scheduled to be completed in December 2019. However, the contractor has until July 2020 to complete all work under contract.

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.
