Beaufort County continues to experience significant growth as tourists, new residents, military personnel, and commercial traffic travel through the Lowcountry every day. Major transportation corridors including Interstate 95, US Highway 278, US Highway 21, and South Carolina Highway 170 serve as critical connections to Hilton Head Island, Bluffton, Beaufort, Charleston, Savannah, and surrounding communities. As traffic volumes increase, congestion and collision risks rise as well. Understanding these major routes can help drivers recognize hazards, avoid common accident locations, and protect themselves and their families when traveling throughout the region.
Malchow Johnson Injury Lawyers represents individuals and families injured in serious vehicle collisions throughout Georgia and South Carolina. Many of the most severe crashes in the Lowcountry occur along the major roadways that connect Beaufort County’s growing communities.







Why Traffic Continues to Increase in Beaufort County
Beaufort County has become one of the fastest-growing regions in South Carolina. Growth along the US 278 corridor has transformed Bluffton into one of the state’s fastest-expanding communities while Hilton Head Island remains a major tourism destination attracting millions of visitors each year.
This combination of tourism, residential development, military activity, and commercial transportation places substantial pressure on local infrastructure. During peak travel periods, thousands of additional vehicles travel through the county every day.
Increased traffic often leads to:
- Rear-end collisions
- Intersection crashes
- Distracted driving accidents
- Lane-change accidents
- Commercial truck collisions
- Motorcycle accidents
- Pedestrian incidents
Understanding where these risks exist begins with understanding the area’s major transportation routes.
Interstate 95: The Gateway to the Lowcountry
Interstate 95 serves as the primary north-south transportation corridor for the East Coast. Visitors traveling from Georgia, Florida, North Carolina, and other states frequently use I-95 before exiting toward Hilton Head, Bluffton, or Beaufort.
The interstate carries:
- Tourist traffic
- Commercial freight traffic
- Long-distance travelers
- Construction vehicles
- Military transportation
Several Beaufort County access points connect drivers from I-95 to local destinations.
Common accident factors on I-95 include:
- Speeding
- Driver fatigue
- Heavy truck traffic
- Sudden lane changes
- Weather-related visibility issues
- Distracted driving
When a high-speed collision occurs on I-95, injuries are often severe due to the force involved.
US Highway 278: The Lifeline to Hilton Head and Bluffton
Few roads are as important to Beaufort County as US Highway 278.
US 278 connects Interstate 95 to Bluffton and Hilton Head Island, making it one of the busiest transportation corridors in the region. The route serves residents, tourists, commercial traffic, and emergency responders.
Traffic congestion along US 278 increases dramatically during:
- Summer tourism season
- Holiday weekends
- Spring break
- Special events
- Hurricane evacuations
Drivers frequently encounter:
- Stop-and-go traffic
- Sudden braking
- Heavy merging activity
- Construction zones
- Distracted tourists unfamiliar with the area
Many crashes occur near major intersections and commercial development areas where traffic patterns change rapidly.
For residents commuting between Bluffton and Hilton Head, US 278 remains one of the most heavily traveled roads in the county.
US Highway 21: Connecting Beaufort and the Sea Islands
US Highway 21 plays a critical role in connecting Beaufort, Port Royal, Lady’s Island, St. Helena Island, Hunting Island, and other coastal communities.
The roadway serves as:
- A primary commuter route
- A military access corridor
- A tourism route
- A hurricane evacuation route
Within Beaufort County, US 21 is known by several local names including Trask Parkway, Parris Island Gateway, and Lady’s Island Drive.
Traffic volumes increase substantially during:
- Marine Corps graduation events
- Tourism seasons
- Weekend travel periods
- Holiday travel
Accidents along US 21 often involve:
- Left-turn collisions
- Intersection crashes
- Rear-end accidents
- Motorcycle crashes
- Pedestrian incidents
Areas near commercial developments and major intersections tend to experience the greatest concentration of traffic conflicts.
South Carolina Highway 170: The Critical Link Between Communities
SC 170 serves as a major east-west corridor connecting Bluffton, Beaufort, and surrounding communities.
The highway crosses the Broad River and helps connect the northern and southern portions of Beaufort County.
Drivers use SC 170 for:
- Daily commuting
- School transportation
- Commercial deliveries
- Access to healthcare facilities
- Travel between Beaufort and Bluffton
As development continues throughout the county, traffic on SC 170 has steadily increased.
Common accident causes include:
- Failure to yield
- Speeding
- Distracted driving
- Unsafe turns
- Aggressive driving during congestion
Because many portions of SC 170 involve higher travel speeds, collisions can produce significant injuries.
Tourism and Traffic Safety Challenges
Tourism remains one of Beaufort County’s largest economic drivers. Nearly two million visitors travel to Beaufort and the Sea Islands annually.
While tourism benefits local businesses, it also creates unique traffic safety concerns.
Visitors may be:
- Unfamiliar with local roads
- Using navigation systems while driving
- Searching for destinations
- Distracted by scenic views
- Unaware of changing traffic patterns
These factors can increase the likelihood of collisions, particularly at busy intersections and congested roadways.
The combination of local traffic and seasonal visitors creates conditions that require heightened awareness from all drivers.
Common Injuries From Major Roadway Accidents
Crashes occurring on I-95, US 278, US 21, and SC 170 often involve substantial force.
Victims may suffer:
- Traumatic brain injuries
- Neck injuries
- Back injuries
- Spinal cord damage
- Broken bones
- Internal injuries
- Permanent disabilities
Medical treatment can continue for months or even years following a serious collision.
Many victims also face:
- Lost wages
- Reduced earning capacity
- Emotional trauma
- Ongoing rehabilitation expenses
