South Carolina consistently ranks among the deadliest states for drivers. Whether it’s the “Malfunction Junction” congestion in the Midlands or the tourist-heavy corridors of the coast, the Palmetto State has specific coordinates that local first responders know all too well.
While high-speed interstates often get the headlines, the real danger frequently lies where roads meet. Based on crash volume, fatality rates, and local notoriety, here are the 4 most dangerous intersections in South Carolina right now.
1. Ashley Phosphate Road & I-26 (North Charleston)
The Undisputed Champion
If you live in the Lowcountry, you knew this would be number one. This interchange is consistently ranked not just as the most dangerous in the state, but often as one of the worst in the entire Southeast.
- The Danger: It is a perfect storm of volume and confusion. Commercial trucks, desperate commuters, and tourists all converge here. The older cloverleaf design forces drivers to weave dangerously—entering traffic has to cross paths with exiting traffic in short, terrifying merge lanes.
- The 2026 Status: Despite continuous talk of redesigns, “Ashley Phosphate” remains the primary bottleneck for North Charleston. Rear-end collisions and sideswipes are practically a daily occurrence here as drivers gamble on tight gaps to exit the interstate.
2. Two Notch Road & Trenholm Road Extension (Columbia)
The Fatal Corridor
While Ashley Phosphate leads in fender benders, this intersection in Northeast Columbia has a darker reputation for fatalities.
- The Stat: In national safety studies (including data from Go Safe Labs), this specific junction has previously been ranked as one of the deadliest intersections in the entire United States.
- The Risk: Two Notch Road acts as a high-speed arterial, but it is lined with business driveways and cross-streets. At Trenholm, drivers frequently attempt to beat the light or turn left across multiple lanes of fast-moving traffic. The high speed of the through-traffic means that when accidents happen here, they are rarely minor.
3. SC Highway 9 & SC Highway 57 (Horry County)
The Coastal Trap
Moving away from the city centers, this intersection near North Myrtle Beach represents the deadly nature of rural SC highways.
- The Layout: As of late 2025, this intersection remains the most crash-prone spot in Horry County. It involves high-speed traffic heading toward the beach meeting local traffic attempting to cross or turn.
- The Hazard: “T-bone” collisions are the primary threat here. Drivers on Highway 57 often misjudge the speed of tourists flying down Highway 9. With no traffic signals to slow the highway traffic in certain approaches, a split-second hesitation can be catastrophic.
4. Woodruff Road & I-385 (Greenville)
The Upstate Gridlock
In Greenville, “Woodruff Road” is synonymous with misery. But the specific interchange where it meets I-385 is the heart of the danger.
- The Chaos: This area is the retail center of the Upstate, home to Costco, Target, and the Magnolia Park complex. The volume of traffic is simply too high for the asphalt.
- The Crash Type: While fatalities are lower here than on Two Notch, the frequency of collisions is staggering. It is a zone of constant distraction—drivers looking for store signs, checking GPS, or aggressively blocking intersections to beat the light. The “lane confusion” here leads to hundreds of sideswipes every year.
