Crews will begin temporary single-lane closures on Interstate 77 near the N.C. 150 exit 36 in Mooresville to build a new 10-lane bridge, including a safety barrier wall and new pavement markings.
Blythe Development, a Charlotte-based contractor, will install the safety barrier wall and add pavement markings during the closures, per a North Carolina Department of Transportation news release.
The NCDOT project will continue construction on a new N.C. 150 bridge over Interstate 77 in Mooresville, linking Iredell and Catawba counties.
The Lake Norman-area project aims to accommodate growing traffic and ease congestion, with work that began last year focusing on drainage, utilities and traffic signal improvements.
The overall 15-mile project is expected to be completed in 2030, according to the NCDOT project page.
Construction began last year with work on storm drainage, utilities and traffic signals, and bridge construction will occur in multiple phases while traffic remains on the existing N.C. 150 lanes.
Bridge construction will occur in multiple phases, with traffic maintained on the existing N.C. 150 lanes throughout the process.
Officials have not specified how long the temporary closures will last.
The closures are part of a $249 million project to improve the I-77 and N.C. 150 interchange and widen N.C. 150 from N.C. 16 in Catawba County to the U.S. 21/N.C. 150 interchange in Mooresville, in the Lake Norman area.
Traffic will shift from the median to the outside lanes once temporary barriers and markings are in place, as interior bridge bents are built.
