Diverging diamond interchange coming to I-73 in Greensboro

Work crews are set to close a portion of Guilford College Rd. this weekend so that pavement wedging work can be done as part of a lane-widening project near High Point Rd.
High Point Road crosses Guilford College RoadNCDOT will close Guilford College Rd. just south of High Point Rd. this morning.  The road should be reopened by 6 pm Sunday, according to a press release.
The work is part of a $40.1 million project begun in 2012 that will eventually see a four-mile section of High Point Rd. widened from two to four lanes.
The new road will have a median and result in the construction of a new interchange with I-73. NCDOT will build the first diverging diamond interchange in the Greensboro area.
“The diverging diamond interchange 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,” the release state. “This innovative design will allow motorists to easily access I-73 from High Point Road and will prevent the congestion and crashes that can occur when vehicles back up on interstate ramps.”
You can see a video of a DDI at work here. The video, as above, shows a sample DDI from another area of North Carolina.
Construction on this project should be complete by late 2015.
