Highway 20 east, about eight miles east of Brothers was closed in both directions after a semi-tanker truck flipped on it's side and spilled some liquid, that could be hazardous.
Oregon State Police closed the roadway just before 8 p.m. Wednesday night at milepost 50, near the intersection with Fredrick Butte Road.
Bend Fire units, Deschutes County sheriff's deputies and ODOT assisted OSP at the scene and set up about a quarter mile perimeter while they attempt to identify the liquid.
Our news partner, News Channel 21 reports that truck drivers coming from the east said they could smell something, and at this time OSP is considering extending the closure.
Hazmat teams were called to the scene around 9:30 p.m. and OSP says they expect the road to be closed for an extended amount of time.
