Coastal to Cajun: Tybee Island to Hattiesburg Road Trip

The drive from Tybee Island, Georgia to Hattiesburg, Mississippi covers approximately 440 miles and takes about 7.5 hours without stops. The route follows I-16 West from Savannah to Macon, then I-75 South to Columbus, GA, and finally I-85 West back to I-65 South through Alabama into Mississippi. A historical fact: the last stretch into Hattiesburg passes through DeLisle, a community originally settled by French Huguenots in the early 1700s, predating the city itself. This back-road segment along US 49 offers a quiet entry compared to the interstate. For more on how to find the best stops and hidden gems between cities, consult our guide.

Tybee Island’s salt marshes give way to the Savannah River’s oaks draped in Spanish moss. As you drive I-16, the landscape shifts from coastal plains to the red clay hills of central Georgia. Near Macon, you’ll pass the Ocmulgee Mounds, a national historical park with Native American earthworks. Further south, the Chattahoochee River valley near Columbus offers forested views. Entering Alabama, the Black Belt region is marked by fertile dark soil, and then pine forests dominate until the Mississippi state line. The final leg on US 49 passes through the DeLisle community, known for its historic 19th-century architecture and local antiques shops.

UNESCO World Heritage Sites: The only UNESCO site near this route is the Savannah Historic District (part of the city’s National Historic Landmark District), though not officially UNESCO. However, Ocmulgee Mounds is a candidate for UNESCO status. For a world heritage detour, drive 1 hour east from Hattiesburg to the Poverty Point World Heritage Site in Louisiana.

• Savannah Historic District (nominal UNESCO) - 22 squares, historic homes, riverfront

Montgomery’s Old Alabama Town showcases 19th-century crafts. In Hattiesburg, the Downtown Historic District offers specialty shops like The Lucky Rabbit and the Hattiesburg Zoo gift shop.

Fuel Efficiency and Costs: Gas prices vary widely along the route. Expect lower prices in Georgia (around $3.10/gal) compared to Mississippi ($2.85/gal). The best place to fill up is just before crossing into Alabama at the Georgia-Alabama line on I-85. Avoid filling up in Macon or Montgomery, where prices spike.

Rest Stops and Service Areas: Georgia has well-maintained rest areas every 30-40 miles on I-16. Alabama’s rest stops are fewer but clean, especially the one at mile marker 135 on I-65. Mississippi’s rest area on US 49 near DeLisle is small but has picnic tables. For longer breaks, consider the Love’s Travel Stop in Hope Hull, AL (I-65 exit 168).
