Legally Reviewed by Brent Stewart: June 01, 2026
Bluffton’s explosive growth as one of South Carolina’s fastest-growing towns has transformed quiet Lowcountry roads into congested corridors where thousands of crashes occur annually. Development concentrated in western Beaufort County has increased vehicle density at key intersections faster than infrastructure can accommodate, creating hazardous conditions for residents and the millions of tourists traveling to nearby Hilton Head Island.

Bluffton’s High-Volume Traffic Corridors
The Bluffton Police Department formed a specialized Traffic Unit in 2016 following receipt of a $205,000 grant from the South Carolina Department of Public Safety. The unit was created specifically to reduce the number of collisions and traffic-related fatalities and injuries by targeting Bluffton’s highest-volume, most dangerous roadways.
The Bluffton Police Department’s Traffic Unit concentrates enforcement efforts on five major corridors known for high traffic volume and frequent crashes:
US Highway 278
This is Bluffton’s busiest and most hazardous highway. Connecting Bluffton and Hilton Head Island, it handles massive traffic from residents, tourists, and resort visitors. The heavy flow often leads to congestion as drivers head toward beaches, top-tier golf courses, and historic Lowcountry destinations. Nationally, US Primary routes are extremely dangerous; for instance, in 2023, these routes were involved in 37,527 collisions, including 272 fatalities statewide. Highway 278 is a significant contributor to Beaufort County’s share of these US Primary route crashes.
SC Highway 170
Linking historic Beaufort to the fast-growing Bluffton area, this route’s traffic has increased substantially as western Beaufort County continues to develop. It constantly manages commercial and residential traffic, as infrastructure improvements have not kept pace with the sustained growth along this corridor.
SC Highway 46
This is another high-traffic corridor in Bluffton that the Police Traffic Unit targets. Recognizable safety hazards along this route led to a comprehensive traffic analysis by Beaufort County Engineering, specifically focusing on safety improvements for the section between SC 170 and Buckwalter Parkway.
Bluffton Parkway
Serving as a primary north-south route within Bluffton’s development area, the Parkway carries substantial daily traffic volume, connecting various neighborhoods, commercial zones, and other main roads.
Buckwalter Parkway
Ranking among Bluffton’s most dangerous roadways, this heavily traveled route is frequently cited in hazardous intersection rankings across Beaufort County. Beaufort County operates over 50 street lights along Buckwalter Parkway to address safety concerns.
