Six months ago, 95 drivers in Easter Sunday traffic crashed on southbound Interstate 77 near Fancy Gap, killing three people.
Officials have reported eight similar crashes during the past 15 years.
Now, state highway officials say new technology in 2015 should help prevent another megacrash.
It happened again Saturday. In the fog and rain on Interstate 77 near Fancy Gap, a driver died in a pile-up, one of many on this stretch of road known for its blinding conditions and low visibility.
The biggest happened six months ago, on March 31.
On that Easter Sunday, the fog captured travelers like a trap with a tight-fitting door. Inside, drivers had only seconds to stop, and rammed into one another. Damaged vehicles and loose vehicle parts littered a mile of the sloping mountainside highway.
A fire broke out. A driver slumped motionless. Those not among the three dead escaped as fast as they could. Some people fled so fast they left their engines and lights on. One couple left behind their dog.
Huge lines of escaped travelers formed on adjacent hillsides watching. Still more cars were coming in and crashing into the wreckage, which grew to 95 vehicles. The flames from the wreckage grew so high the crowd felt the heat.
Finally, troopers and rescuers came running to help.
"It was probably one of the most terrifying things that ever happened to me or my family," said driver Art Ward of Michigan.
Fog had once again obliterated the normal flow of traffic on Interstate 77 at Fancy Gap in Carroll County. An $8.5 million safety upgrade scheduled to be completed in 2015 did these motorists no good.
