ROCKY RIVER -- A Cleveland man is dead after a one-vehicle crash around 10:08 p.m. Sunday.

The Ohio State Highway Patrol says Brent Sheets was exiting I-90 from the westbound lanes to Hilliard Blvd. when his 2005 Chevrolet Cavalier went off the right side of the roadway and struck a guardrail.

The vehicle then crossed both lanes of the ramp, into a wall and flipped to its right side.

Authorities say Sheets, who was not wearing a seat belt at the time of the crash, was partially ejected out of the passenger side's front window.

Sheets was pronounced dead at the scene.

The ramp to Hilliard Blvd. was closed for approximately 3 and a half hours during the investigation.

The cause of the crash is currently unknown.
