The Diverging Diamond Interchange - started in France - imported to Missouri - and slowly appearing in North Carolina - is being proposed at one of the busiest interchanges in the Asheville area. If built, the Interstate 26 interchange with NC 280 will be home of the seventh type interchange within the state.
This interchange also serves Asheville Regional Airport and the area has seen significant growth over the last two decades. Construction on the new DDI interchange should begin in the fall of 2013 at a cost of $6.4 million.
