Officials from Virginia State Police, the Rockbridge County Fire Department, EMS and the sheriff's office responded to the accident. Crews have been working all night to tow the cars off the interstate and clean up the debris.
A couple from North Carolina was part of the pileup. They're car was hit by a tractor trailer, but luckily they weren't hurt. They, and other witnesses , say the weather was the reason for the accident.
"It's like of course the rain and then the sun came out and the sun was so bright and no one could see 50 feet in front of them. We were trying to do the best we could, and then people just started going off the road," said Shay and Danielle Tippens.
In total, 41 vehicles were part of the accident, including tractor trailers and mobile homes. Crews say it was one huge chain reaction, causing one of the largest pileups they've ever seen.
"When I got out, and I looked behind us, I was just like 'Oh my God.' Everything that happened up here happened behind us...but,...it could've been so much worse," said Danielle Tippens.
Rockbridge County crews say the pileup stretched about 1 mile back.
They say they've removed all the cars from the road, but the tractor trailers will stay until Monday night.
