A series of devastating multi-vehicle crashes have resulted in significant traffic disruptions along Interstate 95 in South Carolina. Reports indicate that at least 50 vehicles were involved in a pileup in Clarendon County, with 15 tractor-trailers contributing to the chaos. Dense fog conditions were cited as a contributing factor to these accidents, which included a notable pileup that shut down the southbound lanes over Lake Marion. Emergency services are working to clear the area, but traffic remains heavily backed up with detours in place. Several injuries have been reported, prompting an urgent response from local authorities and a fire department. Motorists are advised to avoid the area as cleanup efforts continue.
