Mount Pleasant, South Carolina – A local bicyclist, 33-year-old Mackensey Griffiths, tragically lost her life on May 22 following a collision with a semi-truck. The accident occurred at the intersection of Long Point Road and the I-526 eastbound off-ramp around 12:18 p.m. Griffiths was pronounced dead one hour later at the Medical University of South Carolina.
The Mount Pleasant Police Department is currently investigating the circumstances surrounding the incident. In the wake of the collision, Long Point Road was closed near the interchange with I-526 for approximately two hours to facilitate the investigation and ensure safety protocols were followed.
This incident has reignited concerns about the safety of cyclists navigating Long Point Road, which is known for its heavy traffic, especially as it leads to the Wando Welch Terminal. Local advocates argue that there is an urgent need for improved infrastructure to promote safety for both pedestrians and cyclists in the area.
Charleston Moves, a local nonprofit organization dedicated to promoting safe cycling and walking paths, has been advocating for improved infrastructure since 1993. The organization’s executive director highlighted that the need for pedestrian and bicycle-safe paths has never been more pressing, especially in light of the recent accident.
Calls for action emphasize that agencies responsible for roadway safety must begin reallocating existing funds to enhance safety measures for both pedestrians and bicyclists. Effective safety initiatives will require collaboration between multiple governmental entities, including Charleston County and the State Department of Transportation.
The accident involving Griffiths sheds light on broader issues regarding cyclist safety on high-traffic roadways. Advocates stress that without significant improvements to the infrastructure, incidents like this may become more frequent, placing vulnerable road users at risk.
