You’re looking at the map, seeing two dots on the Atlantic coast, and thinking it’s a straight shot. It is. But it isn't. The actual distance from Jacksonville to Savannah is roughly 140 miles if you’re sticking to the asphalt of Interstate 95, but that number is a bit of a liar.
I’ve driven this stretch more times than I can count. Sometimes it takes two hours. Sometimes, thanks to a fender bender near the Georgia border or a sudden torrential downpour in the Lowcountry, it takes four. If you just want the raw data: you’re looking at about 130 to 145 miles depending on your starting point in Jax. Jacksonville is massive—the largest city by land area in the contiguous United States—so if you're starting in Mandarin versus Oceanway, you’ve already added twenty minutes to your trip before you even see a "Welcome to Georgia" sign.
Why the Distance From Jacksonville to Savannah Feels Longer Than It Is
Most people expect a breeze. They see "two hours" on Google Maps and figure they’ll be in Forsyth Park by lunch. Usually, you will be. But I-95 through Southeast Georgia is a unique beast. It’s mostly two lanes in some stretches, and the truck traffic is relentless. You’re sandwiched between the Port of Savannah and the logistics hubs of North Florida.
Traffic density matters more than mileage here. When you cross the St. Marys River, you enter Camden County. It’s beautiful, marshy, and notoriously heavily policed. If you’re trying to shave time off that distance from Jacksonville to Savannah, don’t do it with your lead foot. Local deputies are famous for monitoring the stretch between Exit 1 and Exit 29.

The Coastal Bypass vs. The I-95 Slog
If you have an extra hour, stop looking at the odometer. Seriously. While the direct distance from Jacksonville to Savannah is shortest on the interstate, the "real" coastal experience is found on US-17.
US-17 is the old-school highway. It runs parallel to the interstate but takes you through the heart of the Golden Isles and moss-draped towns like Darien. You’ll see the Altamaha River. You’ll see shrimp boats. You’ll also see a lot of traffic lights. It turns a 140-mile trip into a 160-mile odyssey, but the mental distance feels shorter because the scenery actually changes. I-95 is just pine trees and billboards for fireworks or personal injury lawyers. For miles. And miles.
Breaking Down the Logistics: Miles, Minutes, and Fuel
Let's get technical for a second because precision helps with planning.

If you are leaving from the Jacksonville International Airport (JAX), the distance is actually closer to 132 miles. It’s a straight shot. However, if you are coming from Jacksonville Beach, you’re looking at 148 miles. That extra 16 miles doesn’t sound like much until you hit the afternoon rush on I-295.
- Fuel Consumption: Most modern sedans will burn about 4 to 5 gallons of gas on this trip.
- The Halfway Point: Brunswick, Georgia. It’s roughly 70 miles from both cities. If you need to stretch your legs, Exit 38 or 29 are your best bets for food that isn't just a sad heat-lamp burger.
- The Bridge Factor: Entering Savannah often involves the Talmadge Memorial Bridge if you’re coming from certain directions, though usually, from Jax, you'll stay on I-95 North to I-16 East. That final 10-mile stretch on I-16 can be a bottleneck as everyone funnels into the Historic District.
Real-World Obstacles: The Georgia-Florida Line
Weather in the Southeast is no joke. You can be driving in bone-dry 90-degree heat in Duval County and hit a wall of water the second you cross into Georgia. Hydroplaning on I-95 is a genuine risk because the road doesn't always drain as fast as the sky empties.
Then there’s the "Lovebug" season. Twice a year, these little black insects swarm. They won't hurt you, but they will coat your windshield so thickly that your 140-mile trek will require three stops at gas stations just to use the squeegee. It sounds like a minor detail. It’s not. It can add 20 minutes to your "official" travel time.

Hidden Gems Along the 140-Mile Route
Don't just drive. Stop.
Woodbine, Georgia is tiny. But if you're there during the Crawfish Festival, it’s worth the detour. Or check out the Smallest Church in America near Townsend (Exit 67). It’s literally a tiny chapel that fits about 10 people. It’s these weird, quirky stops that make the distance from Jacksonville to Savannah feel like a road trip rather than a commute.
I once spent three hours at the Georgia Sea Turtle Center in Jekyll Island. It’s only about 15 minutes off the highway. If you have kids, that 140-mile drive is going to feel like 1,000 miles unless you break it up. Jekyll or St. Simons are the perfect "halfway" distractions.
Practical Advice for Your Trip
Check the Georgia Department of Transportation (GDOT) 511 app before you leave Jax. Florida’s roads are usually wider, but Georgia’s I-95 is constantly under some form of "maintenance" that turns three lanes into one without much warning.
- Timing is everything. Avoid leaving Jacksonville between 4:00 PM and 6:30 PM. You’ll spend forty minutes just getting out of the city limits.
- The Exit 3 approach. If you need gas right after the border, Exit 3 in Georgia is usually cheaper than the stations right in Jacksonville, thanks to slightly lower state fuel taxes.
- Savannah Parking. Once you finish those 140 miles, don't try to park on the street in the Historic District. Use the Robinson Parking Garage or the Bryan Street Garage. It’ll save you the headache of feeding meters every two hours.
The distance from Jacksonville to Savannah isn't just a number on a dashboard. It’s a transition from the sprawling, modern Florida metro to the slow, hauntingly beautiful Southern Gothic vibe of Savannah. Treat it as a journey, not a race. You'll arrive much less stressed.
Actionable Next Steps
- Check your tires: I-95 is hot and high-speed; low pressure leads to blowouts on this specific stretch.
- Download an offline map: Cell service can actually get spotty in the marshlands between Darien and Richmond Hill.
- Plan your Savannah entry: Decide now if you want the scenic route via Hutchinson Island or the standard I-16 East approach to avoid last-minute lane hopping.
