Aiken Traffic & Road Conditions

Major Highways in Aiken County

Aiken County sits at the convergence of Interstate 20, US-1 / Richland Avenue, US-78, SC-19 / Whiskey Road, and US-278. Together these routes carry essentially every commercial truck, commuter car, and out-of-state visitor that touches Aiken in a given day — which is why a single closure or rolling backup on any one of them ripples across the rest within minutes.

  East-west connector; passes through Aiken to Augusta (west).
• SC-19 / Whiskey Road
