Fuel tanker rollover sparks interest for guardrails on Route 220 Highland County Board of Supervisors will request VDOT safety inspection. Tags: HIGHLAND COUNTY, Va. – More than 1,250 gallons of fuel went unrecovered, killing 870 fish in the Jackson River, after a fuel tanker rollover Friday. Where Friday’s crash happened is a site of concern, as two crashes were reported in the same area last year. Just half a mile south of the tanker crash lies another problematic curve. Highland County Board of Supervisors requested guard rails in the fall for that area after receiving several complaints. But after filing a report with the Virginia Department of Transportation, the area was deemed too narrow to install guardrails.
