The restricted crossing U-turn will open to traffic on the afternoon of Friday, Dec. 9. The project will finish nearly a month ahead of its scheduled Jan. 5, 2017 completion date.
Drivers on Route 718 who wish to access Route 29 northbound will turn right on Route 29 south, then make a U-turn at the new one-way median opening located about 900 feet south of the intersection.
For motorists on Route 29 northbound, a newly extended left-turn lane will provide more room for deceleration before reaching the crossover at Route 718. For southbound Route 29 traffic, the right-turn lane has been shifted right to provide better visibility for drivers waiting to enter Route 29.
Work began on the RCUT intersection in mid-July, and the Route 29 median crossover at Route 718 has been closed since Aug. 8.
Due to an increased speed limit, greater traffic volumes and limited sight distance, VDOT has identified a need to improve safety and traffic operations at the intersection of Route 29 (James Monroe Highway) and Route 718 (Mountain Run Lake Road). In recent years, a significant number of crashes have occurred at the intersection as a result of motorists crossing Route 29 to turn left from Route 718. The project will address these safety concerns without stopping the traffic flow along Route 29.
The RCUT intersection differs from a conventional intersection by eliminating the left turn movement from the cross street. To accommodate this movement, the RCUT intersection requires drivers on Route 718 to turn right onto Route 29 and then make a U-turn maneuver at a one-way median opening about 900 feet past the intersection. The new U-turn crossover location improves sight lines down Route 29 and provides a dedicated lane out of the way of traffic for tractor-trailers and other large vehicles who wish to travel north. The proposed RCUT intersection will be among the first of its kind in Virginia.
With this project, the Route 29 northbound left-turn lane will be extended to provide full deceleration length. The right-turn lane from Route 29 southbound to Route 718 will be offset to improve visibility for motorists turning right from Route 718.
According to a recent study, the Federal Highway Administration found that RCUTs enhance safety, reducing crashes by 28 to 49 percent when compared to a stop-controlled intersection. Crash severity is reduced by 70 percent in fatal crashes and by 42 percent in crashes resulting in injury.
Approximately 27,000 vehicles use this stretch of Route 29 daily, according to 2013 data. The traffic count on Route 718 is 2,350 vehicles per day.
In previous years, safety concerns expressed by Culpeper County officials and residents led to the installation of advance-warning signs and flashers on Route 29. However, greater traffic and an increased speed limit have resulted in the need for additional safety improvements.
A 2011 safety study analyzed traffic volumes and crash history, including six angle crashes in a one-year period, and recommended adding a traffic signal. A signalized intersection design was originally presented at a public hearing on Dec. 4, 2014. Based on comments received at the hearing, VDOT evaluated an alternative design that is cost-effective, addresses safety concerns and can be constructed faster than a signalized intersection.
