CULPEPER — Traffic on U.S. 250 (Richmond Road) will be detoured onto Interstate 64 overnight on Saturday and Sunday while paving work is done on U.S. 250 at the diverging diamond interchange project. During the paving operations, from 9 p.m. Saturday to 7 a.m. Sunday, and from 9 p.m. Sunday to 5 a.m. Monday, only emergency vehicles will be allowed to travel through the work area.

During the paving operations traffic will detour as follows:

• S. 250 Westbound through traffic will use I-64 East to Exit 129 (Route 616 Keswick/Boyd Tavern) then back to U.S. 250. 
• S. 250 Eastbound through traffic will use I-64 West to Exit 121 (Route 20 Charlottesville/Scottsville) then back to U.S. 250.
• I-64 Eastbound to U.S. 250 Westbound traffic will use I-64 East to Exit 129 (Route 616 Keswick/Boyd Tavern) then back to U.S. 250.
• I-64 Westbound to U.S. 250 Eastbound traffic will use I-64 West to Exit 121 (Route 20 Charlottesville/Scottsville) then back to U.S. 250.

When the paving is complete the third lane of U.S. 250 through the interchange will open to traffic, which should alleviate some of the congestion and delays that motorists have been experiencing during peak travel periods.

The diverging diamond interchange briefly shifts vehicles to the opposite side of the road, eliminating traditional left turns that must cross over oncoming traffic. The new interchange will improve 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.

When driving through the diverging diamond configuration, motorists will proceed through a traffic signal at one end of the interchange and follow their lane to the opposite side of the roadway. Motorists who wish to access I-64 will merge left onto the interstate using an on-ramp without having to stop or wait for oncoming traffic to pass. Through traffic on U.S. 250 proceeds to a second traffic signal at the opposite side of the interchange and follows their lane back to the right side of the road.

The $14.3 million project dramatically reduced the cost to improve safety and efficient traffic movement through the interchange compared with reconstructing it as a traditional cloverleaf interchange. No additional right of way was needed and the existing bridges have been used for the new interchange. 

Until construction is complete in February 2023 lane closures will continue during nighttime hours. The speed limit on U.S. 250 through the project is 25 miles per hour.

The diverging diamond interchange is one of six projects in a package of improvements to Albemarle County roads in a $28.5 million design-build contract awarded to Curtis Contracting Inc. of West Point, Va. Wallace Montgomery of Vienna, Va. is providing design services for the projects.

Four projects, the reconfiguration of the I-64 Exit 118 interchange at U.S. 29, an additional lane from I-64 to the Fontaine Avenue exit from U.S. 29 north, the Rio Mills connector road between Rio Mills Road and Berkmar Drive and a roundabout at Route 20 (Stony Point Road) and Route 649 (Proffit Road) are substantially complete. A second roundabout at U.S. 250 (Rockfish Gap Turnpike) and Route 151 (Critzer Shop Road) at Afton is nearing completion.

Current traffic conditions, VDOT’s statewide network of traffic cameras and other real-time travel information is on the 511Virginia website. That information is also available on the free VDOT 511 mobile app or by calling 511 from any phone in Virginia. VDOT updates are also on Facebook and the district’s Twitter account, @VaDOTCulp.
