Macon to St. Simons Island: A Georgia Road Trip Guide

The drive from Macon, GA to St. Simons Island, GA covers roughly 175 miles via I-16 E and US-17 S, typically taking 3 to 3.5 hours without stops. This route traces the fall line from Georgia's Piedmont to its coastal plain, crossing the Ocmulgee River in Macon and ending at the Atlantic Intracoastal Waterway on St. Simons Sound. A lesser-known fact: I-16 from Macon to Savannah was designated as the 'Jim Gillis Historic Savannah Parkway,' but our route diverges at exit 42 onto US-341/GA-27 toward Brunswick.

• Total distance: ~175 miles.
• Driving time: 3–3.5 hours (non-stop).
• Key highways: I-16 E, US-341 S/GA-27, US-17 S, and F.J. Torras Causeway.
