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 In 1948, SC 403 was retracted back to its original routing, leaving behind Hill Road. 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 its Lees Crossroads intersection, removing an intersection corner bypass, giving an odd overlap with SC 403 for to where the corner bypass originally reconnected.
