Overview
VDOT has combined six projects in Albemarle County into one design-build contract. Curtis Contracting Inc, of West Point was awarded the $28.5 million design-build contract in July 2019. Wallace Montgomery will provide design services. The following six projects will be constructed:
- Interstate 64 at exit 118 Interchange Modifications
- Interstate 64 at exit 124 Diverging Diamond Interchange (DDI)
- Fontaine Avenue Ramp Improvements
- Construction of Roundabout at Route 250 and Route 151
- Construction of Roundabout at Route 20 and Route 649
- Rio Mills Road/Berkmar Drive Connection
Under Construction
Interstate 64 at exit 124 Diverging Diamond Interchange:
This project will build a diverging diamond interchange (DDI) on Route 250 and make other low-cost improvements for safety and congestion relief. The work also includes ramp improvements, new signals and signal upgrades, drainage improvements and utility relocations.
By shifting vehicles to the opposite side of the road, this design eliminates traditional left turns that cross over oncoming traffic.
The DDI improves safety by reducing the number of spots where vehicles could collide and can handle more than 600 left-turn movements per hour, twice the capacity of a conventional interchange.
Virginia’s first DDI opened in 2014 at the I-64/Route 15 interchange at Zion Crossroads in Louisa County.

Time Lapse Video
VDOT has installed a time-lapse camera for the diverging diamond interchange. Click here to follow construction activities. A new image will be taken approximately every 10 minutes.
Project Cost: $14.3 million

Construction of Roundabout at Route 20 and Route 649:
This project will convert the intersection of Route 20 (Stony Point Road), Route 649 (Proffit Road) and Route 1494 (Riggory Ridge Road) to a single-lane roundabout to improve safety and traffic flow.

Coming Soon
Construction of Roundabout at Route 250 and Route 151:
The intersection of Route 250 (Rockfish Gap Turnpike) and Route 151 (Critzers Shop Road) in Afton, near the Nelson County line, will be reconstructed as a roundabout.
In recent years there have been an increasing number of crashes at this intersection. This project will improve operations and safety at the busy intersection while managing traffic speeds and correcting geometric deficiencies that have been identified as contributing factors in crashes at the intersection.
A temporary signal was installed in April 2017 as an intermediate measure. Advance warning flashers and in-lane rumble strips have also been installed on the downhill eastbound Route 250 approach to slow traffic.

Recently Completed
Rio Mills Road/Berkmar Drive Connection:
The new Route 643 (Rio Mills Road) connection to Route 1403 (Berkmar Drive) opened to traffic on June 16, 2021. The quarter-mile long two-lane extension runs from the existing Rio Mills Road east to Berkmar Drive, and includes a paved multi-use trail. The trail connects to existing bike lanes, sidewalk and a multi-use path on Berkmar Drive.
With the new road open to traffic, the existing section of Rio Mills Road from the new connection south to Millers Cottage Lane, a private road just north of the South Fork Rivanna River, is closed to traffic. Local traffic will still be able to access the Rivanna River boat launch area just west of U.S. 29 and all private residences along Rio Mills Road maintain access from either end of the road.

Fontaine Avenue Ramp Improvements:
This project involved adding an option lane—through/right-merge lane—at the Fontaine Avenue exit from northbound Route 29. The project was designed to ease weaving issues and remove conflict points.
Project Cost: $1.7 million
UPC 111813
Interstate 64 at exit 118 Interchange Modifications:
This project involved eliminating the loop ramp from southbound Route 29 to eastbound I-64. A dual left-turn lane and a connection to the existing ramp from northbound Route 29 to eastbound I-64 was constructed. This modification eliminated two weave movements that were identified as a factor in many crashes.
Project Cost: $1.8 million
