Tribune/Pete Caster An Idaho State Police trooper stands at the scene of a one-vehicle crash on the Lewiston Grade on Friday afternoon. Ian M. Sullings, 22, of Orofino, was driving south in a gray 2005 Mercury Mariner when he overcorrected while negotiating a curve at about 4:20 p.m., according to an ISP news release. He struck the center barrier, crossed both southbound lanes, overturned and came to rest in the righthand lane. Sullings was wearing a seat belt and was not injured. The lane of U.S. Highway 95 was blocked for about an hour during the investigation. Both southbound lanes were blocked for approximately 10 minutes while a tow truck recovered the vehicle.
