Route description

SC 403 is a two-lane rural highway that traverses for 36.1 miles (58.1 km) beginning north of Lake City, along SC 341. Going through a northeasterly direction to Hobbs Crossroads, it then goes north to Sardis. Connecting with I-95 north of Sardis, it continues north connecting with US 76 near and then through Timmonsville. At Windhams Crossroads, it connects with US 401, where it provides access to I-20. At Lees Crossroads, it overlaps for .2 miles (0.32 km) with US 15 before it ends, along the road towards Hartsville. The vast majority of the landscape along the route is farmland, with the exception in and around Timmonsville.


Established in 1933 as a renumbering of US 301; from US 76, in Timmonsville, to US 15, in Lees Crossroads. The entire route was paved in 1939. Around 1942, SC 403 was extended south SC 407, in Sparrows Crossroads. In 1948, SC 403 was retracted back to its original routing, leaving behind Hill Road (S-21-38). Between 1968-1970, SC 403 was extended south to its current southern terminus with SC 341; replacing part of SC 53 and nearly all of SC 309. Between 2005-2012, US 15 was realigned at Lees Crossroads intersection, removing an intersection corner bypass, giving an odd overlap with SC 403 for .2 miles (0.32 km) to where the corner bypass originally reconnected.

South Carolina Highway 309

South Carolina Highway 309 (SC 309) was established in 1940 as a new primary routing, from SC 341, in Hobbs Crossroads, southeast to US 301. By 1942, it was extended southeast to reconnect with SC 341. Between 1968-1970, SC 309 was renumbered as an extension of SC 403; with only its westernmost piece downgraded to secondary road (Lynches River Road S-42-14).
