Oregon State Police say the driver lost control as an SUV traveled along the bridge around 2:30 yesterday morning and slammed into the side of the span. Police say both women got out of the SUV and called 911, and fell about 80 feet to the bank of the South Umpqua River below. Troopers tell KATU-TV they aren't sure why the women fell from the bridge deck.
