Tybee Island to St. Simons Island: Coastal Georgia Road Trip Guide

The drive from Tybee Island to St. Simons Island along Georgia's coast is roughly 95 miles, taking just under two hours via the I-95 corridor. However, the true journey reveals a tapestry of marshlands, historic forts, and sea islands. A key detail: the route crosses the Savannah River via the Talmadge Memorial Bridge, a cable-stayed bridge soaring 185 feet above the water—one of the tallest in the Southeast. This is not a mere transit; it's an immersion into the Georgia coast's layered history and ecology.
