A bridge on Interstate 95 in South Carolina turned into a field of twisted steel on the morning of October 1: 69 vehicles collided in a chain-reaction crash in dense fog — 15 tractor-trailers and 54 passenger cars — with people trapped, at least one car on fire, and, by sheer luck, no one plunging into the lake below.
Fog locks the bridge, 92 vehicles on it
The crash happened around 8:50 a.m. local time Thursday on the I-95 southbound bridge over Lake Marion, near mile marker 100 between Clarendon and Orangeburg counties. The bridge stretches more than a mile across the largest lake in the state.
Jonathan Belles, a senior digital meteorologist for The Weather Company, said fog formed over Lake Marion near first light Thursday and visibility dropped below a quarter of a mile at times, before mixing out around 10 a.m. Fire officials from the nearby town of Santee said the thick fog gave drivers almost no time to stop.
Ninety-two vehicles were on the bridge at the time; 69 ended up in the wreckage. When first responders were dispatched, they were told it was a six-vehicle collision — the count kept growing as crews arrived.
Two seriously hurt, one airlifted — no deaths
Responders found trucks twisted and smashed, several vehicles wedged beneath tractor-trailers, at least one car burning, and four people entrapped. Firefighters had to walk between wrecks and fight flames with hand-held extinguishers.
At least two people were seriously injured, including one airlifted to the hospital by helicopter; their condition was not immediately available. Seventeen more were taken to McLeod Health Clarendon. Officials confirmed no deaths.
A family headed to Disney World
Noah Mandel was driving his family from Virginia to Walt Disney World when their blue car was swept into the pileup. "It was crazy; it was one of those things that you don't ever think is going to happen to you," he said. "You could see a car behind us just started to smoke and caught on fire. You could see other people in front were trapped in their cars, and you're all just kind of wondering what to do next."
With Lake Marion directly below, the what-ifs were terrifying. "It was definitely a thought in my mind of how lucky we were that no one went over the edge into the water," Mandel said. Nearby residents said they could hear the disaster unfolding from their homes.
Southbound lanes closed 15 hours, tow trucks from across the state
Crews worked for more than 15 hours to clear the wreckage. Officials called in tow companies from across the state before finally reopening all lanes around 6 a.m. Friday, October 2. I-95 is a major East Coast artery from Florida to Maine, so the closure rippled through freight and tourism traffic.
The South Carolina Highway Patrol is investigating. Dense fog is the clearest culprit so far — but why 92 vehicles were on the bridge in near-zero visibility, and whether speed limits and warnings were adequate, are questions the investigation will have to answer.
The practical lesson for long-distance drivers: bridges over lakes and rivers fog up worst at first light. When visibility collapses, the safest move is hazards on, slow down, widen the gap — or simply wait for the fog to lift. The Mandel family didn't make it to Disney World on time, but everyone got home. That matters more.
