- On Saturday, June 28, the N.C. Department of Transportation
will close a section of U.S. 21 at I-40 in Iredell County to begin setting girders for a new bridge that is part of the $89.1 million I-40/I-77 interchange improvement project in Statesville.Beginning at 8 p.m. on Saturday, crews will close one lane of traffic on U.S. 21 at I-40 to prepare to set the girders in place. Both lanes on U.S. 21 under I-40 will be closed at 10 p.m. and will re-open at 9 a.m. on Sunday. A detour in place will have traffic on the north side of I-40 taking exit 150 at N.C. 115 to get back to I-40 East; while traffic on the south side of I-40 can take exit 152 at I-77 North to loop back to I-40 West.Motorists are advised to use caution while traveling in the area and to expect delays. NCDOT reminds motorists to watch signs for construction information, stay alert and obey the posted speed limit. The work is one of the steps in the construction of a multi-level interchange of the two interstates. The project also involves:
The Statesville interchange of I-40/77 was built in late 1960s and has outlived its service life. 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, with an increase to about 110,000 by in 2035.For more information or updates on the I-40/77 interchange improvement project, visit the project website and follow project progress via Twitter. You also can view photos and videos on the project's webpage.For real-time travel information at any time, call 511, visit the NCDOT traffic website or follow NCDOT on Twitter.

- 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.
