By Drooid · · How we work
Core Event
On October 1, 2026, dense fog caused a multi-vehicle collision on the southbound lanes of Interstate 95 crossing Lake Marion at the Clarendon-Orangeburg county line in South Carolina. The crash involved dozens of vehicles on the bridge, prompting the closure of southbound I-95 and a temporary shutdown of northbound traffic. Emergency crews airlifted at least one person to a hospital and treated multiple others for minor injuries.
Background & Context
The bridge over Lake Marion is a major north-south corridor for travelers between Virginia and Florida. Prior to the incident, state officials had warned drivers of “heavy fog” and advised reduced speeds and increased following distance. The sudden loss of visibility on the bridge triggered a chain-reaction pileup that quickly filled the roadway.
Data & Statistics
- Vehicles involved: Reports vary from 40 cars to more than 60 vehicles, with three sources citing 15 tractor-trailers and 50 cars, while another source mentions 69 vehicles (15 18-wheelers and 54 other cars).
- Injuries: At least one person was airlifted; the Santee Fire Service District treated 11 people with minor injuries, and other outlets reported 11 hospitalizations. No fatalities have been confirmed.
- Lane status: Northbound lanes reopened by early afternoon; southbound lanes remained closed into the evening with a detour at Exit 102.
Official Statements & Responses
- The Santee Fire Service District said the pileup occurred around 9 a.m. at I-95’s 100-mile marker and that “four entrapments” were present.
On-the-Ground Reports
Witnesses described the chaos as the fog lifted only after the collision. Noah Mandel, who was driving his family through the area, recalled, “It was crazy, it was one of those things that you don’t ever think is going to happen to you,” — Noah Mandel and added, “It was definitely a thought in my mind of how lucky we were no one went over the edge into the water,” — Noah Mandel. Nearby resident Mike Fausette said, “It was people running in the back of everybody and it was real loud,” — Mike Fausette. Other motorists reported long waits at the Santee Welcome Center and discounted hotel rates offered to stranded travelers.
