Route description
SC 909 is a two-lane rural highway that traverses from U.S. Route 321 (US 321) in Lowrys to SC 9 near Richburg. The route zig-zags in northern Chester County connecting small communities, and provides access to the Chester Catawba Regional Airport.

History
Established in 1940 as a new primary routing, it originally traversed from SC 9 to US 21 in Lewis. In 1941 or 1942, SC 909 was extended both directions: south, from SC 9 to the Knox community, and west from US 21 and through Lowrys to Cassels Road. In 1948, SC 909 was reverted to its original 1940 with both extensions becoming secondary roads. Around 1952, it was re-extended west to its current western terminus at US 321.
