FLOYD COUNTY, Ky. (FOX 56) — Boulders the size of mobile homes are snarling traffic in Floyd County.

This past weekend’s wet weather led to a massive rockslide on Kentucky Route 321. Calls started coming in around 9:30 p.m. Monday.

Officials believe the entire sandstone cliff’s face fell.

A spokesperson for the Kentucky Transportation Cabinet, who’s been working in the area for 20 years, said it’s the biggest rockslide he’s seen.

“A lot goes into it. They’re going to have engineers look at it. It’s not just clean up. We’ve got to make sure that it’s safe to reopen. We’ve got to mitigate the problem to ensure that once we do clean it up and we do open the road again, that it’s safe to be traveled on,” said Captain Ross Shurtleff with the Prestonsburg Police Department.

Crews will have to blast through the rocks to make smaller ones they can haul away.

Officials said it could be weeks before this stretch of Route 321 is reopened.
