North Carolina Highway 105 (NC 105) is a primary state highway in the U.S. state of North Carolina. It traverses from the mountain community of Linville to the town of Boone. Route description NC 105 follows the general route of the old East Tennessee and Western North Carolina Railroad (ET&WNC), also known as the "Tweetsie," connecting Linville to Boone before a major flood washed away many sections of the railbed in 1940. For the most part the highway was not built on the actual railbed. Unlike other roads in the area, it was less curvy and made the most direct route to Boone compared to U.S. Route 221 (US 221) and NC 194. The highway also doubles as a truck route for US 221 (south of US 221 in Boone), US 321 and US 421 (both north of NC 105 Bypass in Boone). The first of the highway are two-lane and go by the gated communities Grandfather Golf & Country Club and Linville Ridge. At the Tynecastle intersection in Linville Gap, it crosses the Eastern Continental Divide and begins to descend into a valley area. On this section of the highway, the south-bound traffic has a passing lane and trucks are required to drive . Once the descent ends, the route briefly passes through the town limits of Seven Devils. Between Seven Devils and Broadstone Road is the unincorporated community of Foscoe. Some of the best views of Grandfather Mountain can be seen at this section of the highway for southbound traffic; it is also notorious for traffic back-ups by travelers trying to stop and visit shops on either side of the road. A brief southbound passing lane is available near Hound Ears. Between Broadstone Road and NC 105 Bypass, the highway ascends towards Boone, and the north-bound traffic expands to two lanes. A rock quarry and asphalt plant are located along the road through here. In Boone, the highway becomes a full four-lane highway for the rest of the route and connects to two major roads: Blowing Rock Road and East King Street. Dedicated and memorial names NC 105 has one dedicated or memorialized stretch of freeway. W Ralph Winkler Highway – Official name of highway, from the Avery/Watauga county line to Blowing Rock Road. It is dedicated to Ralph Winkler, who was a member of the State Highway and Public Works Commission in the 1950s. History Established in
