R-2307: N.C. 150 improvements
The N.C. Department of Transportation is widening N.C. 150 (River Highway) from Greenwood Road in Catawba County to U.S. 21 in Iredell County.
The project includes widening N.C. 150 from two to four lanes between Greenwood Road and Perth Road and four to six lanes between Perth Road and U.S 21, building new bridges at the I-77 interchange and a new bridge over Lake Norman, installing and upgrading traffic signals, and improving drainage in the project corridor.
The project also incorporates reduced conflict intersections, a type of intersection design used to simplify traffic movements by reducing the number of conflict points between vehicles. The most common type eliminates left turns from side roads to main arteries, featuring raised medians to direct traffic from side roads into turning right. Drivers would proceed less than 1,000 feet to a dedicated U-turn location to head in the opposite direction. In addition, a continuous flow intersection will be built at N.C. 150 & Williamson/Bluefield roads.
