On December 2, 2014, at approximately 5:25 A.M., Oregon State Police (OSP) troopers and Oregon Department of Transportation officials responded to a commercial vehicle crash on Highway 58 near milepost 78 on Willamette Pass. Preliminary investigation indicates icy roads may have been a factor as a semi-tractor pulling double trailers lost control and one trailer separated then tipped over, blocking the roadway. The semi was reportedly hauling cargo that may have included a hazardous material. As a precaution, troopers and ODOT personnel have closed the roadway and summoned Haz-Mat teams to the a rea. Additional information will be released when the investigation has been completed. Officials on-scene are unable to provide any details on when the roadway will re-open at this time.
