“It was horrific, it was terrible,” said Loretta who lives near the highway. “There’s no words for it.”

“It’s horrendous, it’s just horrendous. I can’t believe it. I’ve never seen anything like that. Looks like a war zone,” said Laura.

A stretch of the road was closed while the crash was investigated, causing major travel delays.
