Driving from Chattanooga to Myrtle Beach: Route Options, Timing, and What to Plan

The 370-mile drive from Chattanooga to Myrtle Beach takes between 5.5 and 6.5 hours depending on which Interstate corridor you choose. This guide covers the two primary routes, lodging strategies for breaking the trip, and how traffic patterns affect your departure timing.

The Two Main Routes and Their Trade-offs

Interstate 75 South to Interstate 95 South is the most direct path. You'll travel south through Georgia on I-75, pick up I-95 near Jacksonville, Florida, and continue north into South Carolina to reach Myrtle Beach. Total distance is approximately 370 miles. This route passes through Atlanta's metropolitan area, where I-75 frequently experiences congestion between 7 a.m. and 10 a.m. on weekdays and between 4 p.m. and 7 p.m. If you depart Chattanooga before 6 a.m., you'll clear the Atlanta bottleneck before the heaviest traffic arrives. The I-95 corridor near Jacksonville can also back up, particularly around the I-295 interchange.

Interstate 24 East to Interstate 81 South to Interstate 77 South adds roughly 30 miles but avoids Atlanta entirely. This route carries you eastward through the Smoky Mountains region, then south through the Carolinas. The trade-off is time: you gain approximately 45 minutes to an hour in driving duration, though you eliminate the unpredictability of Atlanta rush hour. This path is preferable if you're traveling between 7 a.m. and 5 p.m. on a weekday.

Overnight Lodging Stops and Strategic Breaks

The journey naturally splits at the Georgia-Florida border, roughly 3.5 hours south of Chattanooga. Several mid-point lodging options exist if you want to break the drive.

Savannah, Georgia sits approximately 4 hours south and is a legitimate destination in its own right. Historic District hotels and budget chains cluster near downtown and along the Victory Drive commercial corridor. A night here lets you explore River Street or Forsyth Park without rushing; you can complete the remaining 2.5-hour drive to Myrtle Beach the next morning and arrive by early afternoon. Savannah adds between 1 and 2 hours to your total trip time compared to driving straight through.

Jacksonville, Florida lies almost directly on the I-75/I-95 junction, making it a convenient 4.5-hour stopping point. The downtown riverfront has developed significantly in recent years, with hotels ranging from extended-stay chains to higher-end properties. Jacksonville serves primarily as a rest point rather than a destination; you'll reach Myrtle Beach by mid-morning the next day if you depart by 8 a.m.

Driving straight through is viable if you leave Chattanooga by 5 or 6 a.m. You'll arrive in Myrtle Beach between noon and 2 p.m., avoiding both Atlanta congestion and the need for overnight lodging. This strategy works best for travelers without young children and those comfortable with a single driver rotation.

Fuel and Rest Considerations

Both routes pass numerous rest areas and fuel stops. The I-75 corridor through Georgia offers more dining variety and commercial services at exits. The I-77 corridor through the Carolinas has fewer services between exits, particularly through rural South Carolina; fuel up before leaving Charlotte if taking this route. Florida's Turnpike (a toll road that diverges from I-75 south of the Georgia-Florida border) charges between $3 and $5 depending on your exit, but it bypasses some of Jacksonville's most congested interchange zones.

Arrival Timing and Myrtle Beach Traffic

Myrtle Beach itself experiences significant traffic variation. Summer weekends, particularly Friday afternoons and Sunday mornings during June through August, see severe congestion on Kings Highway (Business 17). Arriving before 3 p.m. on a Friday or after 10 a.m. on a Sunday reduces your wait time entering the city. If you're staying in North Myrtle Beach or South Carolina's Calabash area, you can bypass the main commercial corridor by using Highway 31 or local surface streets.

Practical Takeaway

Depart Chattanooga between 5 and 6 a.m. on the I-75/I-95 route if you want to minimize Atlanta delays and arrive by early afternoon without an overnight stop. If weekday morning departure isn't feasible, the I-24/I-81/I-77 alternative trades 30 extra miles for predictable driving conditions outside peak traffic hours. A Savannah overnight break transforms the drive into a partial vacation rather than pure transit.
