Winston-Salem to Sea Island Road Trip: A Southern Coastal Journey

The road from Winston-Salem, NC to Sea Island, GA spans 368 miles, a journey that begins in the Piedmont Triad and ends on a private barrier island accessible only by a single causeway. The route primarily follows I-40, I-77, I-26, and I-95, but the final 12 miles to Sea Island—via the F.J. Torras Causeway—are unlike any other in the Southeast. This causeway, built in 1927, originally charged a toll of $1 per car, a fact that underscores the island's long history of exclusivity.

The drive takes approximately 6 hours and 15 minutes without stops, but savvy travelers know the real value lies in the detours. From the cobblestone streets of Old Salem in Winston-Salem to the marsh-side oysters of Brunswick, GA, this corridor is dense with cultural and natural attractions. Below is a snapshot of the route's key data points.

I-95 through South Carolina and Georgia has a poor safety reputation due to high speeds and dense truck traffic. Speed limits are 70 mph, but enforcement is sporadic. In 2024, the South Carolina Highway Patrol issued over 10,000 speeding tickets on I-95 between Florence and the Georgia line. For those wondering how long to drive Winston-Salem, NC to Sea Island, GA under safe conditions, add 30 minutes to the base time for defensive driving.

Family-friendly rest stops are abundant. The South Carolina Welcome Center at mile 5 on I-95 just north of the Savannah River has a playground and a pet-friendly walking path. For pets, the entire Sea Island causeway allows dogs on leashes, but the island restricts dogs from most beaches except from dawn to 9 AM.

• Best rest area for kids: Georgia Visitor Center in Savannah (I-95 southbound, mile 115). Interactive displays on coastal ecology and a grassy picnic area.
• Fatigue management tips: Take a 15-minute break every 2 hours. The Citgo station in Ridgeland, SC (exit 8) has a coffee shop with locally roasted beans.
• For those asking is it worth driving Winston-Salem, NC to Sea Island, GA, the answer is a resounding yes, thanks to the ability to tailor the journey with stops like Charleston (via a 30-min detour off I-95) or the Okefenokee Swamp (near Waycross, GA).

The transition from the Piedmont to the Coastal Plain is subtle but distinct. At mile marker 45 on I-77 south of Columbia, the red clay of the Piedmont gives way to the sandy loam of the Sandhills region. This area features longleaf pine forests that once stretched from Virginia to Texas, now fragmented but still visible around the Carolina Sandhills National Wildlife Refuge.

Further south, the route crosses the Savannah River at mile 159 on I-95, marking entry into Georgia's Lowcountry. Here, the landscape flattens, with blackwater creeks and marshland—a preview of Sea Island's own salt marshes. The local commerce along US-17 from Savannah to Brunswick is dominated by roadside produce stands and seafood markets. Don't miss the shrimp at Russo's Seafood in Darien (mile 12 on US-17).

• Natural attractions to stop at: Congaree National Park (30 min off I-77 near Columbia), with boardwalk trails through old-growth floodplain forest.
• Local commerce highlight: The art galleries and antique shops in downtown Beaufort, SC (exit 33 on US-21).

The primary arteries—I-40 and I-95—are well-maintained, but the final approach to Sea Island requires a toll road. The F.J. Torras Causeway costs $3 for passenger cars (cash only as of 2025), so keep quarters handy. Fuel economy across this route averages 25-30 mpg for modern vehicles, translating to about 12-15 gallons of gas for the full trip.

Gas stations cluster near exits, but gaps exist. Between Florence, SC and Savannah, GA, there is a 60-mile stretch (exit 141 to exit 87 on I-95) with only one station—the Flying J in Hardeeville, SC. Fill up before crossing into Georgia to avoid premium prices near resort areas.

• Best fuel stop between Winston-Salem and Columbia: Buc-ee's in Florence, SC (exit 170 on I-95). Clean restrooms and cheap gas.
• Sea Island's nearest gas station: Shell on Demere Road, St. Simons Island (1 mile from causeway).
• Recommended driving times: Leave Winston-Salem by 8 AM to avoid Charlotte traffic (I-77 through Charlotte peaks 7-10 AM).
