SC 46 runs northeast along Bluffton Road, but slightly more than halfway along this segment it encounters another traffic circle, this time with Bluffton Parkway. South Carolina Highway 46 ends at US 278 across from a gated community known as "The Crescent." History Established in 1939 as a renumbering of part of SC 33, it originally ran from SC 5 near Hardeeville to Bluffton then south to Brighton Beach. In 1956, SC 46 was rerouted at Bluffton: north replacing part of SC 462 then east to a ferry to Hilton Head Island; its old alignment to Brighton Beach became Alljoy Road (S-7-13). In 1957, the ferry to Hilton Head Island was replaced with bridges leaving behind Fording Island Road (S-7-242). By 1967, SC 46 was truncated at its current endpoint north of Bluffton; all east of point became part of US 278. The first SC 46 was an original state route; from SC 41 in Moncks Corner, to SC 45 in Ferguson. In 1939, SC 46 was renumbered as part of SC 6. Today, much of old SC 46 is under Lake Moultrie. Major Intersections South Carolina Highway 46Y South Carolina Highway 46Y (SC 46Y) was a connector that was established by 1940 between U.S. Route 17 (US 17) and SC 46 in Hardeeville.
