How Beaufort County Moves: Highways, Commutes & Freight

A driver's-eye reference to the interstates, US highways, commute corridors, and freight infrastructure that define how Beaufort gets where it's going.

Major Highways in Beaufort County

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

• I-20
  Primary east-west corridor connecting Beaufort to Savannah/I-95 (W) and Charleston (E) via US-17; primary commuter and industrial route for the Lowcountry coastal corridor.

Commute Patterns & Regional Drives

Beaufort commuters operate on a regional grid, not a city grid. Here is how long the most-driven trips actually take from Beaufort:

The volume comes with a cost. Beaufort County recorded 62 traffic fatalities in 2024 — roughly 14.6 per 100,000 residents, per the SC Department of Public Safety fact book.

Freight, Inland Port & Airport Traffic

Add Beaufort Executive Airport (Lady's Island) to the picture. It is the region's primary commercial airport, and the drive in from Beaufort is a short hop.

All figures sourced from state DOT traffic counts, the state Department of Public Safety fact book, the regional ports authority, and the local airport district — refreshed as new annual reports drop. Live conditions, accidents, and lane closures are above; this section explains the system those incidents move through.
