South Carolina Highway 151

South Carolina Highway 151 (SC 151) is a 52.850 mi primary state highway in the U.S. state of South Carolina. Known as "the road to the beach" by many residents of the Charlotte metropolitan area due to it being the most direct route to the Grand Strand, it connects the Charlotte metropolitan area to Darlington, Florence, and the aforementioned Grand Strand.

Route description
SC 151 is a four-lane and mostly divided highway from Darlington to Pageland. For several segments, the road is five lanes, with four travel lanes and a center turn lane.

SC 151 starts in Pageland, splitting off from US 601 to bypass the town's business district. Heading southward, it also bypasses Jefferson, heads through downtown McBee, and bypasses Hartsville. In downtown McBee, the speed limit is 25 MPH, and on several segments of the route, the limit is 60 MPH. Past McBee, the route takes on a more east-west direction, which it maintains until its southern terminus in Darlington.

History
The first SC 151 was established in 1927 as a new primary routing between U.S. Route 29 (US 29)/SC 15 in Anderson, to SC 20 in Williamston. By 1930, it was renumbered as SC 248.

The current SC 151 was established in 1937 as a renumbering of SC 35 from Darlington to the North Carolina state line. By 1952, SC 151 was truncated at SC 9 in Pageland, its route north to the state line replaced by US 601. By 1958, SC 151 replaced SC 151 Alternate (SC 151 Alt.), bypassing Hartsville. In 1983, SC 151 was extended and bypassed east of Pageland, to its current northern terminus. In 1997, SC 151 was bypassed east of Jefferson.
