Drivers on I-77 near Lake Norman are facing new lane closures as crews build a massive 10-lane bridge over the interstate.
Temporary single-lane closures began this week near Exit 36 and N.C. 150 in Mooresville. Crews are installing a new safety barrier and pavement markings before shifting traffic.
Once that work is complete, I-77 traffic will move from the median toward the outside lanes. Crews will then begin constructing interior supports for the new N.C. 150 bridge.
The finished bridge will be about 160 feet wide and carry 10 travel lanes across I-77. Construction is being completed in phases while the existing bridge remains in use.
The work is part of a $249 million overhaul of N.C. 150 and the I-77 interchange.
The larger project will widen N.C. 150 between the Lake Norman area and Mooresville, rebuild the interchange and add another bridge across Lake Norman.
NCDOT says the improvements are designed to handle growing traffic and reduce congestion along one of the Lake Norman region’s busiest corridors.
The overall project is scheduled for completion in spring 2030.
