RALEIGH — Construction will begin on the new I-40/77 interchange in Statesville later this month.

N.C. Department of Transportation Secretary Gene Conti has awarded an $89.1 million contract to Zachry Construction Corp. of San Antonio, Texas to reconstruct and improve the interchange.

The Statesville interchange was built in late 1960s and has outlived its service life, the DOT said. The current configuration does not meet today’s design guidelines.

Originally, the traffic projections through the area were about 5,000 vehicles per day. Today, the traffic on both interstates through the area is about 70,000 vehicles per day, and is projected to grow to about 110,000 in 2035.

Work can begin as early as July 30 and be completed by March 14, 2017.

There will be several phases of the project, including:

– Constructing a multi-level interchange of the two interstates;
– Widening I-40 from four to six lanes from N.C. 115 to Old Mocksville Road.
– Constructing parallel lanes on I-40 that will allow vehicles to access U.S. 21, as well as accessing I-40 from U.S. 21, without disrupting the flow of traffic;
– Reconstructing U.S. 21 from just north of Glenway Drive to BB&T on Sullivan Road south of I-40, with a diverging diamond interchange at I-40;
– Reconstructing the bridge on Radio Road;
– Building a new bridge over U.S. 21 and Fourth Creek;
– Building a new bridge from Sunset Hill Road to Gaither Road. This is being done as the access to Gaither Road from U.S. 21 will be eliminated. The only access to Gaither Road will be from the new bridge on Sunset Hill Road; and
– Closing the existing interchange at Old U.S. 64.
