The N.C. Department of Transportation will implement a new design at the intersection of N.C. 73 and U.S. 21 in Huntersville at 10 p.m. Wednesday, March 7, weather permitting.

The intersection design, called a “quadrant left”, will reduce congestion by eliminating left turns from N.C. 73 to U.S. 21 and using connector roads to keep traffic moving.  

Once the intersection opens, other changes will be made in the project limits to accommodate the new design:

  • Left turn lanes will be removed from N.C. 73 East and West to U.S. 21;
  • Left turns will be removed from U.S. 21 South to Holly Point Drive;
  • A flashing yellow arrow will be added to permit left turns from U.S. 21 North and South to N.C. 73.

·        New signing and pavement markings will be added to reflect the changed traffic patterns

NC 73 Eastbound

This is the second time this design is being used in North Carolina.  The state’s first quadrant left intersection is at Main Street and Hillandale Road in Durham.  This design is  common in Ohio and Michigan.  A visualization of the Huntersville intersection can be seen below or by clicking here. 

The contractor, Blythe Development Co. of Charlotte, will be working to finish final paving operations on U.S. 21, N.C. 115, and Holly Point Drive prior to the project’s completion in April.

The work is part the N.C. 73 Widening Project, a $17 million design-build project funded with monies from the American Recovery and Reinvestment Act.  Construction began in November 2009 to widen N.C. 73 from two to four lanes with center turn lanes from west of U.S. 21 to east of N.C. 115.
