DIAMOND BAR — A 29-year-old Arcadia man died after being run over by a big rig following a freeway motorcycle crash in Diamond Bar Wednesday afternoon, officials said.
The name of the motorcyclist was not released Wednesday pending notification of his family, Los Angeles County Department of Coroner Lt. Joe Bale said.
He was pronounced dead at the scene of the crash, which occurred about 8:35 a.m. on the transition road connecting the southbound 57 Freeway to the westbound 60 Freeway, just north of Grand Avenue, according to California Highway Officer Rodrigo Jimenez.
The cyclist was riding a 2007 Suzuki GSX-R in the No. 3 lane when he approached a slower-moving 2014 Honda Civic being driven at 20 to 30 mph, Jimenez said. A big rig was also travelling at 10 to 15 mph behind the motorcycle in the No. 3 lane.
“A collision between the Honda Civic and the Suzuki motorcycle occurred,” Jimenez said. “It is unclear at this time how the collision occurred.”
“Subsequently, the rider of the motorcycle was ejected and the Suzuki fell over onto its right side,” Jimenez said. “The motorcycle rider was then struck by the left rear tires of a tractor-trailer combination and sustained fatal injuries as a result.”
CHP officials issued a Sig Alert for more than two hours for the right two lanes of the transition road as they cleared the wreckage and conducted an investigation.
No arrests were made as the investigation continued, officials said.
Any witnesses or anyone with information was asked to contact CHP Officer R. Green at the Baldwin Park office of the CHP at 626-338-1164.
