The Douglas County Sheriff’s Department said alcohol may be to blame for a wrong-way crash on Kansas Highway 10 overnight that seriously injured a 22-year-old Olathe man.

John Angelo was transported via air ambulance to Kansas University Hospital in Kansas City after the single-car accident on K-10 early Tuesday morning west of Eudora.

Douglas County Sheriff’s Department spokesman Sgt. Steve Lewis said Angelo was driving east in the westbound lanes of K-10 when he crashed his 2002 Saturn into a road construction site at the Wakarusa River bridge.

According to Lewis, the accident report indicates alcohol was a contributing factor to the crash.

The accident happened at 2:18 a.m. It took emergency crews nearly an hour to free Angelo from his car, Lewis said.

A sheriff’s deputy in the area conducting a routine car stop witnessed Angelo’s vehicle and a semi-truck take action to avoid a head-on collision, Lewis said.

The driver of the truck was not injured.

The highway was at least partially closed to traffic until about 3:50 a.m.
