KANSAS CITY, Kan. (AP) — Authorities say a tractor-truck driver has survived after his rig went off the side of a Kansas City, Kansas, highway overpass and fell about 60 feet to the ground below.

The Kansas Highway Patrol says the driver is in serious condition after failing to negotiate a curve around 4 p.m. Sunday on Interstate 670 near Interstate 70.

KHP spokeswoman Tiffany Bush says the truck was carrying produce.

A witness, Bill Newcamp of Atchison, said he was waiting for a work crew near the overpass when he saw the truck fall. He says it’s a “miracle” the driver is alive.
