North Carolina Highway 136 (NC 136) is a 2.22-mile (3.57 km) North Carolina state highway that runs entirely within Currituck County. It is a short spur of U.S. Route 158 (US 158), connecting the U.S. Highway to the small unincorporated community of Poplar Branch. The route's eastern terminus is at a boat launch on the Currituck Sound. Prior to 2002, NC 136's current alignment was known as NC 3. In 2002, the numbering of this road and of what was then NC 136 which was located in Iredell and Cabarrus counties swapped to place NC 3 near the home of Dale Earnhardt, a deceased NASCAR driver from Kannapolis who drove the number 3 car.
