Top 10 Most Dangerous Intersections in South Carolina

South Carolina is a vibrant state with bustling cities, scenic coastal highways, and growing suburban areas. However, this growth brings increased traffic and, unfortunately, more accidents. Certain intersections across the state have become hotspots for crashes due to heavy commuter volumes, complex traffic patterns, and challenging road designs. Understanding where these high-risk intersections are can help drivers stay alert and safer on the road. Below, we highlight South Carolina’s ten deadliest intersections based on recent crash data and local hazard factors.

1. I-26 & I-20 Interchange (“Malfunction Junction”), Columbia

Known as “Malfunction Junction,” this complex, heavily trafficked interchange in South Carolina connects two major interstates, handling constant commuter, freight, and local traffic. Tight merges and short weaving distances cause frequent backups, sudden stops, and risky lane changes, raising collision risks. Peak hours and bad weather worsen congestion and visibility, leading to pileups and rear-end crashes.

2. US-17 Bypass & SC-544, Myrtle Beach

This intersection is in a busy tourist corridor with surging traffic during beach season. The US-17 Bypass is a high-speed route around Myrtle Beach, but congestion from shopping centers, hotels, and restaurants causes frequent delays. Multiple turning lanes with high pedestrian activity create dangerous conflict zones. Visitors unfamiliar with the area often miss signal changes or attempt risky lane merges, leading to many angle and rear-end crashes. Pedestrian crossings near commercial hubs increase vehicle-pedestrian collision risks, especially during peak hours.

3. US-17 & SC-41, Mount Pleasant

In Mount Pleasant’s growing suburb, this intersection has become more dangerous due to rising traffic. Shopping centers, restaurants, and homes funnel vehicles through a few turn lanes. Drivers impatient for left turns often make risky maneuvers, and driveway entrances along SC-41 increase conflict points. Rush hours and pedestrian activity in commercial areas add to the risk of side- and rear-end collisions.

4. I-85 & I-385 Interchange, Greenville

Serving as a critical connection between Greenville and Spartanburg, this interchange carries a significant mix of passenger vehicles and heavy freight trucks. The presence of ongoing construction projects often narrows lanes and creates unexpected bottlenecks. The merging areas between the two interstates are particularly hazardous due to the short distances and high-speed traffic. Nighttime driving is riskier here because of poor lighting and reduced visibility. Winter weather can also create slick conditions, leading to a greater frequency of rear-end crashes and sideswipe incidents. Drivers unfamiliar with the layout may hesitate or brake suddenly, causing chain reaction collisions.

5. I-26 & Harbison Boulevard, Columbia

Situated in a busy retail district, this intersection experiences a constant flow of shoppers entering and exiting the area throughout the day. The presence of multiple entrance and exit ramps to and from the interstate creates frequent weaving movements that disrupt traffic flow. Stop-and-go traffic is common, especially during peak shopping hours, leading to frustration and risky lane changes. Drivers may misjudge gaps in traffic or fail to signal lane changes, resulting in sideswipe or rear-end crashes. The intersection’s complexity requires heightened driver attention, but distractions often lead to collisions.

6. US-17 & SC-707, Murrells Inlet

This intersection is a key point on a popular coastal route used by tourists visiting Murrells Inlet and nearby beaches, and it is known to be a high-risk area for accidents. It sees high summer traffic, with many unfamiliar drivers. Left turns onto SC-707 are common and challenging due to fast US-17 traffic. Pedestrian crossings near waterfront dining and shopping increase accident risk, especially at night or during events. Seasonal congestion causes aggressive driving, like sudden lane changes and red-light running.

7. US-521 & SC-160, Indian Land

Indian Land is a fast-growing suburb with a mix of local residents and commuters passing through. This intersection experiences frequent congestion as traffic volumes have outpaced infrastructure improvements. Signal timing issues cause long waits, prompting some drivers to take risks, including running red lights or making unsafe turns. The presence of schools and community centers near the intersection adds to pedestrian activity, increasing the chance of vehicle-pedestrian crashes. Drivers must navigate multiple lanes with confusing signage, and heavy rush-hour volumes increase the chances of rear-end collisions.

8. US-21 & SC-160, Fort Mill

Close to the Charlotte metropolitan area, this intersection handles a mix of local traffic, commuters, and regional travelers. Rush hour congestion is intense, often causing stop-and-go conditions. The intersection’s multiple lanes and complex turning patterns can confuse drivers, especially those unfamiliar with the area. Aggressive driving behaviors, such as abrupt lane changes and speeding through yellow lights, are common here. High traffic volumes combined with pedestrian crossings near schools and parks require extra caution, but unfortunately, collisions involving vehicles and pedestrians remain frequent.

9. US-378 & Sunset Boulevard (US-1), Lexington

The intersection of US-378 and Sunset Boulevard (US-1) in Lexington is considered a high-risk area for accidents, according to local reports. It ranks among the busiest in Lexington County, with 88 accidents recorded at the Corley Mill Road intersection from 2022 to 2024. This area is part of the larger “Sunset Split” project aimed at enhancing traffic flow and safety. Key factors contributing to its danger include: high traffic volume, particularly during peak hours and congestion, which significantly increases the likelihood of rear-end collisions. The busy retail corridor nearby attracts considerable traffic, leading to unexpected stops at driveways and unsafe maneuvers during rush hour. Limited sight distances and distracted driving further increase the risk of accidents.

10. US-17 & SC-22 Interchange, North Myrtle Beach

Serving as a key gateway to the coast, this interchange deals with a significant influx of tourist traffic, particularly during summer and holiday seasons. The high-speed traffic merging onto SC-22, combined with heavy local traffic, creates challenging driving conditions. Seasonal surges lead to congestion and aggressive driving, with frequent weaving and sudden braking. Limited signage and short acceleration lanes can easily confuse out-of-town drivers. Pedestrian activity near nearby shopping and entertainment centers adds to the complexity, increasing the risk of crashes.

Safety Tips for Drivers in South Carolina

Driving safely in South Carolina means staying aware of local road conditions, traffic patterns, and seasonal hazards. Whether you’re navigating busy urban intersections or rural highways, following key safety practices can help prevent crashes and protect everyone on the road. Here are some essential tips every South Carolina driver should keep in mind.

• Drive Defensively at All Times
  Many crashes occur because of aggressive or distracted drivers. Keep your distance from tailgaters, avoid unnecessary lane changes, and never assume another driver will yield. Staying defensive gives you more time to react to unexpected situations.
  
  
• Watch for Changing Weather Conditions
  South Carolina is prone to sudden downpours, fog, and even hurricane-related conditions that can drastically reduce visibility and road grip. Slow down during adverse weather and increase your following distance. Hydroplaning is a common hazard during heavy rain.
  
  
• Use Extra Caution in Rural Areas
  Rural roads often have sharp curves, poor lighting, and limited shoulders. These areas also tend to see more wildlife crossings, especially at dawn and dusk. Slow down, use high beams when safe, and stay alert for deer and other animals.
  
  
• Avoid Distractions Behind the Wheel
  South Carolina consistently ranks among the worst states for distracted driving. Don’t text, check social media, or use GPS while driving unless your phone is mounted and voice-controlled. Even a few seconds of inattention can lead to disaster.
  
  
• Obey Speed Limits and Traffic Signs
  Speeding remains one of the leading causes of fatal crashes in the state. Many of South Carolina’s most dangerous roads, like US-17 and I-95, see frequent speed-related accidents. Always follow posted speed limits and slow down for curves, construction zones, and school areas.
  
  
• Stay Sober and Alert
  Drunk and drug-impaired driving remains a serious problem across the state. Never get behind the wheel if you’re under the influence of alcohol, marijuana, or any other impairing substance. Also, avoid driving when drowsy, fatigue can impair your judgment as much as alcohol.
  
  
• Use Turn Signals and Check Blind Spots
  Simple habits like signaling before turning or merging can prevent accidents. Always double-check your blind spots, especially on multi-lane highways or when navigating busy city traffic in places like Columbia or Greenville.
  
  
• Wear Your Seatbelt Every Time
  Buckling up is the single most effective way to protect yourself in a crash. Make sure everyone in your vehicle wears a seatbelt, no matter how short the trip.
  
  
• Be Patient in Tourist Areas
  South Carolina is a major tourist destination, especially along the coast. Be prepared for unfamiliar drivers, frequent stops, and pedestrians near attractions like Myrtle Beach or Hilton Head. Slow down and give others extra space.
  
  

By following these safety tips, you can help protect yourself, your passengers, and other road users. Awareness, patience, and responsible driving habits go a long way toward preventing accidents on South Carolina’s most hazardous roadways.
