Q. I was under the impression that Blackwell Road was going to be moved a hundred yards or so to the south of where it currently exits onto Route 133. I believe the intersection was placed so a traffic light could be installed there to aid traffic flow, especially during rush hour. Could you provide a status of this effort?
A. According to Belville Town Clerk Athina Williams, Blackwell Road will still be relocated, but the N.C. Department of Transportation has approved a new highway project called a diverging diamond interchange for that section of N.C. 133 at Village Road. As a result, the original Blackwell Road realignment project has been modified.
According to the DOT’s plan, the project improvements will include the following:
• Adding a lane in each direction on the causeway;
• Adding an exclusive left-turn lane at the U.S. 17-74-421 and Battleship Road intersection;
• Replacing the northbound bridge over Alligator Creek;
• Replacing the southbound bridge over Alligator Creek;
• Widening both bridges over the Brunswick River;
• Realigning Blackwell Road about 600 feet south on N.C. 133 (River Road);
• Constructing a “diverging diamond” interchange at the River Road/Village Road interchange.
The DOT is scheduled to begin constructing the diverging diamond interchange next year. The interchange is designed to move a high volume of traffic through an intersection without increasing the total number of lanes.
It accomplishes this by allowing two directions of traffic to temporarily cross to the opposite side of the road at an intersection controlled by a traffic light. It will likely be the first of its kind in the state.

Why is the traffic light at the intersection of Ploof Road and U.S. 17 north in Leland/Belville set to stop northbound traffic even when there is no traffic attempting to turn onto or from Ploof Road?
