An injury accident occurred on I-70 westbound, just before the Lecompton interchange at about 1 a.m. Monday. At least one person was transported to Lawrence Memorial Hospital by helicopter from the scene.

A 23-year-old Maryland man was injured in a rollover accident early Monday on Interstate 70 near the Lecompton interchange northwest of Lawrence and flown to a Kansas City-area hospital, according to the Kansas Turnpike Authority.

According to an accident report, Peter Raymond Robie, of Cambridge, Md., at 12:30 a.m. was re-entering the westbound lanes of the turnpike from the entrance ramp in a 2008 Ford pickup truck. As he steered back into the right lane, the truck drifted off the road and struck a delineator post.

Robie overcorrected his steering of the vehicle, and the truck rolled onto its top and slipped backward into a guardrail and later into the right shoulder on its top, according to authorities.

According to the report, Robie was not wearing a seat belt, and he was ejected from the vehicle. He landed in the right lane. Master Trooper Jeff Heryford said Monday night that investigators believed Robie fell asleep at the wheel.

He was flown via a helicopter ambulance to Kansas University Hospital in Kansas City, Kan. Heryford said that Robie remained in surgical intensive care with several head injuries.
