Courthouse Road Widening & Interchange with I-95 Relocation

I-95 - SR-630 INTERCHANGE

- VDOT Project

DESCRIPTION

- Relocate the Exit 140 interchange slightly south of the existing interchange 
- Relocate the intersection of Courthouse Road and US-1 to the south to align with Hospital Center Boulevard
- Courthouse Road will be widened to four lanes between US-1 and I-95
- West of I-95, Courthouse Road will be widened to four lanes to just west of Ramoth Church Road SR-628 / Winding Creek Road SR-732 
- Temporary traffic signal and pedestrian crossing is located at the entrance to Colonial Forge High School and Liberty Knolls subdivision 
- Permanent traffic signal to 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 (VDOT) is constructing this project using the design-build procurement method

INFORMATION

- Traffic entering and exiting I-95 northbound at Exit 140 (Courthouse Road) is shifted onto new temporary ramps to provide space for crews to build bridge abutments as part of the new diverging diamond 
- Drivers will continue to use the existing Exit 140 interchange until the end of construction in July 2020 
- 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
- Speed limit is reduced to 35 mph on Courthouse Road between Woodcutters Road SR-2350 and Cedar Lane
- Speed limit was reduced 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

Courthouse Road Park & Ride Lot
- Relocate and expand the VDOT Park & Ride lot on Courthouse Road
- Two new Park & Ride lots will open along the relocated Courthouse Road east of I-95 - lots will have a total of 1,100 parking spaces when construction is complete in 2020
- A lot north of Courthouse Road will have approximately 850 parking spaces, and will include a dedicated carpool / vanpool pickup and drop-off area to assist with High Occupancy Vehicle (HOV) use
- The lot will have a dedicated bus drop-off 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 - existing Park & Ride lot will remain open until that time
- This summer the existing lot will be closed - 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 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
- Traffic analysis in the form of an Interchange Modification Report was performed on the diverging diamond interchange concept - the findings were approved by the Federal Highway Administration
