Greensboro’s first Diverging Diamond Interchange (DDI) opens May 13-14.

It's located at I-73 (southern Urban Loop) and the revamped
W. Gate City Boulevard (formerly High Point Road).

The interchange is  part of the High Point Road project (U-2412B), which widened roadway segments between Hilltop and Vickery Chapel roads. 

According to NC Department of Transportation (NCDOT) officials, a DDI is unique because it allows traffic moving in two directions to temporarily cross to the left side of the road, moving a high volume of traffic through the intersection without increasing the number of lanes and traffic signals.

"This innovative design will allow motorists to easily access I-73 from W. Gate City Boulevard and prevent congestion and crashes that can occur when vehicles back up on interstate ramps," one NCDOT official said.
