BEND, Ore. — Traffic is already a headache in Central Oregon as thousands of people arrive before Monday’s total solar eclipse. The Oregon Department of Transportation says traffic was backed up for more than a dozen miles Wednesday night along U.S. Highway 26 east of Prineville. The Bulletin newspaper reports traffic was congested throughout the day, with the roads full of travelers heading to Symbiosis, a 30,000-person festival that starts Thursday near Prineville. About 200,000 people are expected to visit Central Oregon in the coming days to see the rare celestial event.
