- 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.
- A wider Courthouse Road provides more lane capacity, and a new connection with Route 1.
- The intersection Ramoth Church Road and Winding Creek Road has been realigned. New traffic signals were added to the entrance of Colonial Forge High School and the Liberty Knolls subdivision, and the intersection of Ramoth Church Road and Winding Creek Road.
- Two new Park & Ride lots with a combined 1,100 parking spaces are under construction as part of this project. The new lots are located east of I-95. During construction, a temporary lot remains open with 545 parking spaces to provide continuous Park & Ride access at Exit 140.
- By spring 2020, the finished Park & Ride lots will open with a dedicated pickup and dropoff area for buses, carpools, vanpools and public transit.
