LOUISVILLE (WHAS11) – A woman in her thirties is dead after a crash at Stites Station Road and Dixie Highway in southwest Jefferson County on Thursday morning.

The crash involved a semi and a van. The driver of the van died at the scene.

The Louisville Metro Police Department said the semi was turning left into a construction lot and the van rear-ended it.

“It was a very hard impact. It scooted that heavy semi-truck up about five or six feet," LMPD spokesperson Lamont Washington said. “We just want to once again stress, and I don’t know if it was part of this accident, but driving is an important thing, and it’s a privilege. Make sure you’re not distracted when you’re doing it.”

Police made it very clear that it's still too early to confirm what caused the collision, but there were a lot of cars nearby since this happened around the morning rush hour. LMPD said those witnesses are helping them piece together what led up to the crash, with several of them saying they didn't see any braking before the impact. Neighbors said they could hear the collision from hundreds of feet away.

“I just heard a real loud boom. It was no brakes, no screeching brakes, it was just like something blew up. I knew it was bad from where I was sitting. We came out and saw it, and it was terrible," neighbor Darryl Woosley said.

Woosley said this area of Dixie Highway is no stranger to bad crashes and that speeding is a common problem, especially late at night. A tow truck driver was recently killed nearby, and there is still a memorial standing in his honor at the scene.

“This stretch through here is just terrible," Woosley said. “I hate that it happened, but something needs to be done.”

Dixie Highway is closed at Stites Station Road.

Expect delays in the area.

LMPD says they are working to clear the scene.
