7/12/12 Sheriff John Evans reports yesterday, Wednesday, afternoon at about 4:45 pm. There is a significant highway project going on this summer to improve SR-49 between the Town of Downieville and the Yuba Pass which is about 17 miles north of the Town of Sierra City. Yesterday it is reported that one asphalt truck which was still loaded, ran an empty truck off the road causing the second empty load driver to jack-knife. As you can see in the photos, the crashed truck ended up blocking both lanes of SR-49 for over an hour before Cal-Trans workers were able to clear the highway for at least one lane of controlled traffic. The collision is being investigated by Officer Zach Kostik #42-23. Officer Kostik is the Downieville resident post officer for the Grass Valley Area Office of the California Highway Patrol. The out-of-the-area male driver received an injury to his head. He was treated by the Downieville Ambulance crew and Fire Department and was flown by helicopter ambulance to an area hospital. It is believed that the driver of the other involved asphalt truck was identified and contacted.
