Tybee Island to Brunswick GA: Coastal Road Trip Guide

The route from Tybee Island to Brunswick follows US-80 and I-95 south for roughly 80 miles (about 1.5 hours without stops), skirting the edge of the vast Altamaha River delta—one of the largest undeveloped estuaries on the Atlantic coast. A local driving quirk: the Tybee Island causeway (US-80) floods during king tides, so check tide charts before departing. This corridor connects two historic port towns: Tybee, a barrier island with a 275-year-old lighthouse, and Brunswick, home to the iconic Golden Isles.

US-80 connects Tybee to Savannah, then I-95 runs south through marshlands to Brunswick. Drive time is about 1.5 hours without stops. For the question how long to drive Tybee Island, GA to Brunswick, GA, expect 1.5–2 hours depending on traffic. Is it worth driving? Absolutely—the route offers diverse stops and scenery.
