An accident involving two vehicles towing travel trailers shutdown eastbound Interstate 84 west of Hood River for over four hours on Sunday.  According to the Oregon State Police, an SUV and 24-foot trailer driven by a 67-year-old man from Michigan was attempting to pass a pickup towing a 32-foot trailer near milepost 56 at around 11:45 Sunday morning.  An initial investigation showed the SUV was negotiating a left hand curve in the fast lane and was in the process of passing the pickup/trailer combination when the SUV left its lane and hit the pickup/trailer combo, causing it to roll onto it driver’s side.  The Michigan couple in the SUV were uninjured, while the five in the truck, all from Idaho, were taken Providence Hood River Memorial Hospital for treatment of non-life threatening injuries.  The eastbound lanes of I-84 were closed for just over four hours on Sunday while the vehicles were removed.
