South Carolina Highway 51 is a primary state highway in the U.S. state of South Carolina. It is unique for being signed in two different locations in the state; the first section from Georgetown to Florence, the second section in Fort Mill.

Route description[edit]

The first SC 51 begins at US 701 near Georgetown, goes northwest and ends at US 76 in Florence and concurrency with SC 41. Majority of the route is a two-lane rural road, except through Hemingway, Johnsonville, and Florence, where it has four lanes.

The second SC 51 is a short 1-mile (1.6 km) road that starts at US 21 and ends at the North Carolina state line, continuing on as NC 51 through Pineville. The route is only 2-lane, expanding to 4-lane at the state line.


Established as a new routing in either 1925 or 1926; the original route ran from SC 40 (today as US 701) along Choppee Road to Hemmingway then onto Florence, ending at SC 41 (current US 52-301). The route was fully paved by 1939. In the early 1960s, the SC 51 was rerouted as a concurrency with SC 41 from Hemmingway to Rhems, then to US 701 near Georgetown. In 1978, SC 51 was extended in Florence to US 76.[3]

The second SC 51 was established in 1969, when US 21 was rerouted to its current alignment to I-77. The number was a result of an extension of NC 51 that replaced the old US 21 route through Pineville. SC 51 is a result of keeping the route consistent across the border.[3][4]
