On May 9, 2016 at about 4:23PM, OSP Troopers and emergency personnel responded to the report of a semi-truck and trailer roll over on Interstate 5 northbound near milepost 191.5 (just south of Eugene). Initial investigation revealed a 2015 Volvo tractor towing a box trailer (loaded with chocolate ) was traveling northbound on Interstate 5 when it drifted off the right shoulder striking the guardrail. The truck damaged over 300 feet of guardrail before rolling over and blocking the fast lane of Interstate 5. The driver, Robert K CASADOS, age 24, of Anderson, California was not injured in the crash. Both northbound lanes of Interstate 5 were closed for about 30 minutes. The slow lane was then opened for traffic to pass. The highway was completely cleared of the wreckage about four hours after the crash. CASADOS was cited for Failure to Drive Within Lane (violation).
