Fire crews responded to 3 motor vehicle collisions in the Sweet Home area today within a 3 hour time span. The first crash occurred at 4:30pm, on Main Street near the intersection of 23rd Ave. That crash was non-injury with minor damage to the 2 vehicles involved. The second crash occurred approximately 30 minutes later at the intersection of Highway 20 and Liberty Rd. That crash involved a pickup truck pulling a loaded horse trailer, and a small sedan. The driver of the sedan was extricated by firefighters and transported to the hospital by ambulance with serious injuries, but in stable condition. No other injuries were reported and the horses were also uninjured. The third crash occurred at approximately 7:20 pm on Highway 20 near the intersection of 55th Ave. That crash involved a full size pickup truck that struck the back of a smaller pickup truck which was traveling in the same direction. The smaller pickup rolled onto its top in the ditch, with both vehicles sustaining significant damage. During the crash a chain was thrown from one of the pickup beds, tangling in an overhead power line and bringing that live wire down. Pacific Power responded and cut power to the wire which was causing a significant hazard as bystanders were walking under it and driving over it on the roadway. Three occupants of the smaller pickup and the driver of the full size pickup were evaluated by medics but all refused transport to the hospital by ambulance. The calls were all handled by Sweet Home Fire crews, including 2 ambulances, 1 rescue unit, 2 Command Vehicles, and 1 brush truck. Fire crews were assisted by OSP, ODOT, and Sweet Home PD.
