Charlotte is getting the first one in North Carolina.
The new intersection at North Carolina Highway 16 and Mount Holly-Huntersville Road opens Friday. It's part of a $7.2 million contract.
According to the North Carolina Department of Transportation, the design improves traffic flow and increases the efficiency of an intersection because left-turning traffic is separated from the main traffic flow.
Drivers will enter the left turn lane and come to a traffic signal about 500 feet from the intersection. Once it turns green, drivers will cross the opposing lanes of N.C. 16 before arriving at a second traffic signal to continue left.
