An 18-year-old man was killed this morning when his motorcycle crashed on the Orange (57) Freeway in San Dimas, temporarily shutting down several freeway lanes, a California Highway Patrol officer said.
The crash happened about 9:50 a.m. on the northbound 57 Freeway, just south of the Foothill (210) Freeway, CHP Officer Ed Jacobs said.
A SIG alert was issued at 10 a.m. that was expected to last for about for about two hours while officers investigate the incident, California Highway Parol officials said.
"The rider crashed his bike in lane Number 2 and was pronounced dead at the scene," Jacobs said. "I don't know yet if another vehicle was involved in the accident."
The CHP issued a SigAlert at 10:11 a.m. and shut down the Number 1, 2 and 3 lanes on the Orange Freeway for the death investigation, Jacobs said. There was no word yet on how long the lanes would be closed.
The crash remains under investigation by the CHP.
