Project Overview
Traffic Information
What's traffic like in the I-40/I-77 Interchange project area in Iredell County?
The N.C. Department of Transportation has completed major improvements to the Interstate 40/77 interchange in Statesville
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 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 junction of the two interstates.
Collector-distributor lanes separated thru traffic from entering/exiting traffic for specific interchanges. This type of separation created less traffic congestion and safer driving. The I-40/I-77 interchange became a partial turbine because of the cloverleaf ramp remaining in place from I-77 southbound to I-40 eastbound.
This work has improved mobility 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 I-40/I-77 interchange is a critical component of North Carolina's highway system. Built in the late 1960s, the current configuration has outlived its original purpose.
The project was delivered using a design-build method which means the contractor had partnered with a design firm to develop the plans and build the project.
