"Diverging Diamond" interchange will be in final pattern next week
CHARLOTTE -The N.C. Department of Transportation is preparing to convert Poplar Tent Road over I-85 in Concord to a diverging diamond interchange (DDI), one of two on the $125.2 million I-85 widening project and one of four currently under construction in the Charlotte region.
The DDI moves high volumes of traffic through an intersection without increasing the number of lanes and traffic signals while providing easier access to an interstate. Other interchanges are nearing completion on I-85 at N.C. 73 in Concord, on I-77 at Catawba Avenue in Cornelius, and on I-485 at Mallard Creek Road in Charlotte.
To prepare for this new traffic pattern, NCDOT and Lane Construction have scheduled the following:
Friday, Sept. 5:
At 9 a.m., crews will partially close Poplar Tent Road over I-85. Motorists can only exit I-85 North to Poplar Tent Road westbound until 7 p.m.
At 7 p.m., Poplar Tent Road will completely close over I-85 until 6 a.m. Monday, Sept. 8.
Over the weekend, motorists wishing to exit I-85 North and South to Poplar Tent Road will be restricted to right turns and will not be able to cross over I-85. George Liles Parkway is the recommended alternate route.
Monday, Sept. 8:
At 6 a.m., crews will open the DDI in its final pattern. This video shows how traffic flows through the DDI.
NCDOT reminds motorists to watch signs for construction information, stay alert and obey the posted speed limit.
