I-40/77 Interchange

​​​​Project Overview

The N.C. Department of Transportation is continuing to make improvements to the I-40/77 interchange in Statesville with the start of the second phase of the project.  

The first phase involved widening I-40 from four to six lanes in each direction from Old Mocksville Road to east of N.C. 115 and revising the U.S. 21 interchange to a Diverging Diamond interchange​.  

The second phase is focused on collector-distributor lanes on I-40 East, widening I-77 from Exit 49B to north of the I-40 interchange, and building a partial turbine interchange at the two interstates.

The project delivery method is design-build, which means the contractor has partnered with a design firm to develop the plans and build the project. 

Work will help improve congestion as well as safety. The interchange currently sees more than 70,000 vehicles per day, and traffic is projected to grow to 110,000 vehicles per day by 2035.

The intersection is a critical component​ of North Carolina's highway system. Built in the late 1960s, the current configuration has outlived its original purpose.​
