LONE PINE, OR -- O’Neil Highway is back open after a rock truck overturned, near Lone Pine. The crash occurred just after 11 a.m. Monday, about four miles east of Highway 97.

The semi damaged the guardrail, spilled its load and leaked diesel fuel, prompting a clean-up effort that shutdown Highway 370 for most of the day.

6:45 a.m. UPDATE: The Oregon Department of Transportation says O'Neil Highway will close again at 7:30 Tuesday morning, to allow recovery operations to continue. Officials expect the closure to remain for most of the day and say drivers should find another route.
