High Quality Content by WIKIPEDIA articles! NC 136 is a 2.2-mile (3.5 km) North Carolina state highway that runs entirely within Currituck County. It is a short spur of 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 NC 3. The two routes swapped designations in 2002 to put NC 3 near the home of Dale Earnhardt, a deceased NASCAR driver from Kannapolis that drove the #3 car.
