North Carolina Highway 150

In Gaston County, NC 150 downgrades to a street. It travels through central Cherryville, North Carolina, where it meets NC 274. After crossing into Cleveland County, the route travels through Waco and across a small part of Kings Mountain Reservoir. Shortly after crossing NC 180, NC 150 enters Shelby, where it joins US 74 Business westbound. In downtown, NC 150 switches roads to share NC 18 south out of town. Two miles after crossing the mainline US 74, NC 150 and NC 18 split. NC 150 heads due west to Boiling Springs, where the route turns due south across the Broad River to end at the South Carolina state line. SC 150 continues south across the line toward I-85 again and Gaffney, South Carolina.

After crossing a couple of bridges across Lake Norman, Marshall Steam Station is visible on the right. NC 150 continues past the power plant through the lake-oriented communities of Terrell and Sherrills Ford, crossing over numerous tributaries of the lake/Catawba River. Shortly after meeting NC 16 at a four-way intersection, NC 150 crosses into Lincoln County. In Lincolnton, NC 150 and NC 27 join for a two-mile (3.2 km) segment through a commercial district, splitting shortly after an interchange with the US 321 freeway. Through the entire NC 27 concurrency, NC 150 is also concurrent with North Carolina Bicycle Route 6.[2] NC 150 continues southward, along with NC 155 and the business route of US 321, after the split east of downtown. Shortly outside the town, NC 150 splits from NC 155 and heads in a southwest direction through Crouse and across the county line where NC 150 becomes an expressway.

Continuing on westbound NC 150, the route crosses the Yadkin into Rowan County along with US 29/70 on Wil-Cox Bridge while a new bridge is built. The three conjoined highways continue together through downtown Spencer, passing Spencer Shops, and split in downtown Salisbury. NC 150 heads due west once again toward Mooresville, crossing into Iredell County.

Just outside Mooresville, NC 150 joins NC 152 for a short 0.25-mile (0.40 km) concurrency before splitting on a northern bypass route (Oak Ridge Farm Highway), skipping downtown Mooresville. After crossing NC 801 and NC 115, the highway enters a dense commercial shopping area along Plaza Drive. This stretch of road has witnessed massive growth in the early 2000s (decade) with the construction of numerous big box stores as a result of the growing popularity of nearby Lake Norman and the local NASCAR racing culture. As a consequence, NC 150 through western Mooresville was widened to a 4-lane boulevard in the early 2000s (decade). This developed area continues past NC 150's interchanges with US 21 and I-77. A few miles after crossing the Interstate, NC 150 returns to a two-lane road known as River Highway. The route enters the Lake Norman area, passing many businesses tailored to tourists, fishermen, and boating enthusiasts, before actually crossing the lake into Catawba County.

At I-85, NC 150's routing used to be quite unusual. Before the reconstruction of the I-85 through the area, the westbound NC 150 roadway merged onto I-85 southbound lanes and the routes were concurrent for about 0.25 miles (0.40 km) before NC 150 left-exited with US 29/70 southward. Northbound US 29/70 and eastbound NC 150 entered I-85 northbound on the left and the NC 150 exit ramp was immediately on the right. Since it was nearly impossible for one traveling on NC 150 northbound to exit there, motorists were directed to the next exit, Clark Road, which returned to the main roadway using TO NC 150 signs. In the late 2000s, I-85 received a new Yadkin River crossing, which also eliminated the awkward left exit and entrance for NC 150 and US 29/70. NC 150 is no longer concurrent with I-85, but instead follows US 29/70 on a new parallel road down to the Yadkin River crossing. Near the Churchland community, NC 150 takes an odd turn east, despite being signed west, toward I-85/US 29/70/52 to avoid crossing the Yadkin River. The highway passes through an interchange with US 64 and continues into the communities of Tyro and Reeds. NC 150 becomes a two-lane road again as the highway continues southward (signed west) through the community of Arcadia.

When entering Forsyth County, Peters Creek Parkway carries NC 150 using the partial controlled access grade with a speed limit of 55 mph (89 km/h). NC 150 enters the city of Winston-Salem at this point. It then passes a diamond interchange with Clemmonsville Road, before downgrading to a four-laned boulevard with a speed limit of 45 mph (72 km/h). It passes a trumpet interchange with Interstate 40 and Silas Creek Parkway (NC-67) at an at-grade junction. It enters a commercially developed area near downtown Winston-Salem, before it leaves Peters Creek Parkway at a folded-diamond interchange with U.S. 421, also known as Salem Parkway in most of the area, using a controlled-access grade after over a mile. After its concurrency with U.S. 421 for nearly twelve miles, it leaves U.S. 421 at an interchange with Macy Grove Road. Using Macy Grove Road, NC 150 effectively bypasses downtown Kernersville using a limited access grade with a speed limit of 45 mph (72 km/h). It passes a one quadrant interchange with Mountain Street before entering a residential area with superstreets. NC 150 leaves Macy Grove Road at an intersection with Main Street shortly before entering Oak Ridge.

NC 150 travels west from its eastern terminus at U.S. Route 158 (US 158) in rural Caswell County on a winding two-lane road into Rockingham County. Shortly after crossing the county line, NC 150 has a short 1-mile-long (1.6 km) concurrency with NC 87 through the unincorporated community of Williamsburg. NC 150 exits the concurrency to the south, crossing into Guilford County shortly thereafter. As It enters Osceola, it turns right at a junction with NC 61, which has its northern terminus here. NC 150, remaining a two-lane route, continues westward again, through the small community of Monticello, before coming to an interchange with Future Interstate 785 (I-785) and US 29.

Slowing to a 35 mph (56 km/h) speed limit after the interchange, NC 150 progresses towards Browns Summit, the first of three northern Greensboro suburbs the route passes through. After passing through a small road kink at a railroad crossing in the middle of Browns Summit, the route makes its way entirely across the rural community, thereby effectively bypassing Greensboro and remaining north of the county. As NC 150 approaches Summerfield (another suburb), numerous housing developments can be seen on either side of the road. NC 150 enters Summerfield's commercial district, at the US 220 and Auburn Road junction, where a handful of shopping centers can be found, and then turns right and shares a short 1.3-mile (2.1 km) concurrency with US 220 northbound. Continuing west again with the name "Oak Ridge Road", NC 150 encounters an interchange with Interstate 73. After that, NC 150 enters the final Greensboro suburb of Oak Ridge, where it passes by the Oak Ridge Military Academy at its intersection with NC 68. NC 150 continues on a southwest course out of Oak Ridge and Guilford County.

North Carolina Highway 150A (NC 150A) was established in 1956 when NC 150 was rerouted onto new primary routing bypassing southeast of downtown Lincolnton; the old alignment became NC 150A. The route followed West Highway 150 to Riverside Drive, where it linked-up with NC 27. In concurrency, it goes through downtown area via Main Street and Court Square Drive before linking back with NC 150 at Generals Boulevard. In 1960, NC 150A was decommissioned, leaving NC 27 through most of it and downgrade for West Highway 150 (SR 1407).

North Carolina Highway 150A (NC 150A) was established between 1950 and 1953 as a renumbering of NC 150 along McLand Street and Main Street through downtown Mooresville. Around 1955, NC 150 was completely removed from the downtown area and NC 150A was renumbered as NC 152.
