Lexington Traffic & Road Conditions

Major Highways in Lexington County

Lexington County sits at the convergence of Interstate 20, Interstate 26, US Highway 1, and US Highway 378. Together these routes carry essentially every commercial truck, commuter car, and out-of-state visitor that touches Lexington in a given day — which is why a single closure or rolling backup on any one of them ripples across the rest within minutes.

• Interstate 20
  Primary interstate access; runs along Lexington's northern edge, connecting to Columbia (east) and Augusta, GA (west).
• Interstate 26
  Runs approximately 8 miles northeast of Lexington; connects to Charleston (southeast) and Spartanburg/Asheville (northwest).
• US Highway 1
  Main Street corridor through downtown Lexington.
• US Highway 378
  Sunset Boulevard retail corridor through Lexington.
