Highway straightening project takes twists and turns - NewsFlash - OregonLive.com: "The straightened route cuts through forestlands that range in elevation from 300 to 700 feet above sea level. Engineers, trying to bridge eight streams, encounter steep slopes of 30 and 40 degrees. And in the winter, 70 to 100 inches of rain aren't uncommon, making the time available to work on the steepest slopes only a few months in the summer season."
