Driving from Greenville SC to Myrtle Beach SC is a common trip across northeastern South Carolina. The most common route uses I-95 S from Greenville toward Charleston, then loops back via US-17 S or SC-90 to reach Myrtle Beach, typically covering about 100 to 115 miles depending on the chosen path. Nonstop drive times usually range from about 1 hour 45 minutes to 2 hours 30 minutes, with longer durations during rush hours, holiday weekends, or when weather and construction slow traffic.
Primary route options and directions
Travelers usually choose between two main corridor strategies: the inland I-95 route and the coastal scenic option. The I-95-based route is the most direct and efficient for most drivers. The coastal route offers lower speeds, more at-grade intersections, and frequent stops, but can be preferable in heavy I-95 congestion or for drivers who prefer ocean views.
I-95 S and US-17 S corridor (most common)
From downtown Greenville, get onto I-95 S via I-85 S or local connectors. Stay on I-95 S for roughly 80–90 miles, then take the US-17 S/Monte Landing Road or SC-90/Johnnie Dodds Blvd exit toward Myrtle Beach. This corridor balances speed and directness, with multiple service areas and fuel options. Expect variable traffic near the I-95/US-17 merge and around the Grand Strand entry points.
Alternative coastal route via SC-90 and US-17
For a scenic alternative, some drivers take local roads and SC-90 closer to the coast, joining US-17 S south of the main tourist corridor. This path reduces interstate density but includes more traffic lights, lower speed limits, and tourist-heavy arterials. It is often slower than I-95 + US-17 but can be smoother during peak I-95 congestion or when beach event traffic builds near the shoreline.
Distance and time benchmarks
Distance and drive time vary by routing, traffic, and how far you are from the city core in Greenville or the specific Myrtle Beach exit. Below are typical ranges based on common start and end points.
| Route profile | Distance range (mi) | Nonstop drive time range (min) | Source type |
|---|---|---|---|
| Greenville to downtown Myrtle Beach via I-95 S + US-17 S | 100–115 | 105–150 | Mapping consensus |
| Greenville to coastal Myrtle Beach (northern end) via SC-90 corridor | 105–120 | 110–160 | Mapping consensus |
| Rural, off-peak conditions | — | 90–110 | Best-case benchmark |
| Weekend or event traffic | — | 150–210+ | Observed peak conditions |
Traffic and timing considerations
Traffic on the I-95 corridor can be heavy during weekday rush hours and peak holiday periods, especially near the I-95/I-26 merge and approaches to the Grand Strand. Friday afternoons and Sunday evenings commonly see significant volume. Use real-time navigation apps to check speeds and incidents before and during the drive. Leaving earlier in the day can help you avoid the worst congestion and maximize beach time.
Tolls and costs
There are no tolls on the primary Greenville to Myrtle Beach routes described above. Main costs include fuel, vehicle wear, and any parking or lodging fees at your destination. Fuel costs vary with vehicle efficiency and current prices; a mid-sized car getting around 25–30 mpg might use roughly $15–$30 of fuel each way at current national average prices. Toll-free routing keeps expenses predictable, though budget for potential parking fees near beachfront towns if you plan to park on busy blocks.
Weather, construction, and planning tips
Summer thunderstorms and occasional tropical systems can slow travel along the coast, while winter events are rarer but can cause significant delays. Coastal sections, particularly US-17 near the shoreline, are more prone to weather-related slowdowns. Check conditions before you leave and consider flexible timing to avoid the worst of rain or surf-related road issues. For events and peak season days, arrive early or use navigation tools to identify the least-congested option at that moment.
