You're standing in your kitchen in Buckhead or maybe sitting in traffic on I-285, thinking about the ocean. You want salt air. You want a boardwalk. But then the big question hits: how far is Atlanta to Myrtle Beach SC and is it actually worth the seat time?
It’s about 360 miles. Give or take.
If you look at a map, it seems like a straight shot across Georgia and South Carolina. It isn't. Not even close. Depending on whether you're leaving from Alpharetta or the Southside, and whether you hit that nightmare bottleneck in Columbia, you're looking at anywhere from five and a half to seven hours of your life spent behind the wheel.
Most people assume it’s a quick hop. It’s a trek. But for thousands of Georgians every summer, it’s a mandatory pilgrimage.
Mapping the Mileage: The Logistics of the Drive
When you calculate how far is Atlanta to Myrtle Beach SC, the odometer usually settles right around 355 to 365 miles.
The most common route takes you down I-20 East. You’ll stay on that for what feels like an eternity—about 215 miles—until you hit Columbia, South Carolina. This is where the "distance" becomes less about miles and more about your patience.
Columbia is the pivot point.
Once you get through the capital of SC, you transition to US-378 or US-76. This is where the scenery changes from six-lane interstates to pine trees and small-town gas stations. You’ll pass through places like Turbeville. If you aren't careful, you'll miss the speed limit change, and a local deputy will be happy to explain it to you. Honestly, the "distance" isn't the hard part; it's the transition from high-speed highway to the stop-and-go of the Grand Strand’s outskirts.
Is there a faster way?
Some folks swear by taking I-85 North to I-385, then cutting across. Don't do that. It adds nearly 40 miles to the trip. Stick to I-20. It’s boring, sure, but it’s the most direct path to the sand.
Traffic, Construction, and the Columbia Variable
Let's talk about Columbia for a second. It is the literal gatekeeper of your vacation.
The "Malfunction Junction" area where I-26 and I-20 meet has been under construction for years as part of the Carolina Crossroads project. According to the South Carolina Department of Transportation (SCDOT), this multi-phase project is one of the largest infrastructure investments in state history. For you? It means that even though the mileage hasn't changed, the time it takes to cover that mileage varies wildly.

On a Tuesday at 10:00 AM, you’ll breeze through.
On a Friday at 4:30 PM? Add an hour. At least.
The heat in Columbia during July is also no joke. If your AC is acting up, this is where you'll find out. It’s often five degrees hotter in the middle of the state than it is on either end of your trip.
Fueling Up and Chowing Down
You’re going to need a break.
If you’re measuring how far is Atlanta to Myrtle Beach SC by how many snacks you can consume, you’ve got options. Augusta is a solid halfway point for a quick stretch. If you want something better than a fast-food burger, wait until you get closer to the SC line.
- The Peach Orchard: Right off the highway in South Carolina, you’ll find plenty of roadside stands.
- Buc-ee’s: Okay, so there isn’t a Buc-ee’s directly on the I-20 to Myrtle path yet (though one is in Florence, which is a slight detour north). Most Atlanta travelers end up stopping at the Love's in Madison or one of the sprawling plazas near Lexington, SC.
Pro tip: Fill your tank in Georgia if you can, though South Carolina gas prices used to be significantly lower, the gap has closed quite a bit lately due to tax adjustments in both states. Check an app like GasBuddy before you cross the Savannah River.
Beyond the Odometer: Why the Drive Matters
Why do we do it?
Why drive nearly 400 miles when we have lakes closer to home?
It’s the change in the air. When you get about 40 miles outside of Myrtle Beach, the smell changes. The humidity gets heavy, but it carries that distinct Atlantic brine. You start seeing the "Palmetto" influence everywhere.
The Grand Strand isn't just one beach. It’s a 60-mile stretch. So, if your GPS says you’ve "arrived" in Myrtle Beach, but your hotel is actually in North Myrtle or down in Murrells Inlet, you might have another 30 to 45 minutes of driving once you reach the coast. This is a huge mistake first-timers make.

Traffic on Highway 17 (the "Bypass") can be just as thick as the Downtown Connector in Atlanta during peak season.
Technical Breakdown of the Route
For those who want the nitty-gritty details of the path:
Starting in Downtown Atlanta (let’s use the Gold Dome as a landmark), you merge onto I-20 East. You’ll stay in Georgia for about 140 miles. You cross the Savannah River into North Augusta, South Carolina. From there, it’s another 65 miles to the outskirts of Columbia.
After navigating the I-20/I-26 interchange, most travelers stay on I-20 until Exit 141 for I-95 South toward Savannah, then quickly exit onto US-527 or continue to US-76 East.
Total driving time without stops: roughly 5 hours and 45 minutes.
Total driving time with kids, a dog, and a bathroom break: 7 hours.
Misconceptions About the Distance
A lot of people think Savannah is closer.
It is. Savannah is only about 250 miles from Atlanta.
So why go the extra 110 miles to Myrtle?
Myrtle Beach offers a completely different vibe. It’s high-rises, neon lights, and massive water parks. Savannah (and nearby Tybee Island) is more about history and quiet marshes. If you want the "Vegas by the Sea" experience, the extra mileage to Myrtle Beach is non-negotiable.
Another misconception is that flying is always better. Delta and Southwest both run flights from Hartsfield-Jackson (ATL) to Myrtle Beach International (MYR). The flight is only about 1 hour and 10 minutes. However, by the time you get to ATL two hours early, deal with TSA, land, and rent a car, you’ve spent five hours anyway.

Safety and Road Conditions
The stretch of I-20 between Augusta and Columbia is notorious for being straight and, frankly, a bit hypnotic. Highway hypnosis is real.
The South Carolina Department of Public Safety often increases patrols during holiday weekends like Memorial Day or the Fourth of July. They aren't just looking for speeders; they're looking for distracted drivers.
Also, watch the weather. Summer thunderstorms in the South are sudden and violent. If you're hitting a wall of rain near Florence, pull over. Those coastal storms move fast, but they can drop visibility to near zero in seconds.
Final Logistics Check
If you’re planning this trip this weekend, here is exactly what you need to do.
Check your tire pressure before you hit I-20. The heat on the pavement in the middle of Georgia can cause old tires to delaminate or blow out if they’re under-inflated.
Download your podcasts or playlists before you leave. There are several "dead zones" once you get off the interstate in South Carolina where cell service becomes spotty, and you don’t want to be stuck listening to static while navigating the backroads of Sumter County.
Next Steps for Your Trip:
- Departure Time: Leave Atlanta before 6:30 AM or after 7:00 PM. Anything in between means you’re fighting the city's internal traffic before you even get to the open road.
- The Columbia Bypass: Consider using I-77 to loop around the northern side of Columbia if the radio reports heavy delays on I-20. It adds a few miles but saves your sanity.
- Destination Mapping: Double-check if your destination is "Myrtle Beach," "North Myrtle Beach," or "Garden City." Each adds a different amount of time to that final leg of the journey on US-501.
- Hydration: Bring more water than you think you need. The humidity transition from the Piedmont to the Coastal Plain can be draining.
The drive is long, but once you see that first SkyWheel sign, the 360 miles won't matter anymore. You're at the beach.
