GRANDVIEW — A 19-year-old Sunnyside man was injured Monday night when he lost control of his motorcycle on a ramp to Interstate 82 near Grandview.

The Washington State Patrol said Adam Charles Nading was taken to Prosser Memorial Hospital for treatment of his injuries.

A patrol accident memorandum said Nading was entering the freeway at exit 73 when excessive speed caused him to drive off the road surface.

The 1981 Suzuki motorcycle sustained $700 damage. Nading was wearing a helmet.

Drugs and alcohol were not factors in the accident, troopers said.
