DIAMOND BAR — A pregnant woman was flown to the hospital via helicopter Sunday following a two-car wreck on the Pomona (60) Freeway in Diamond Bar, officials said.
The crash was reported just after 12:20 p.m. in the westbound lanes of the freeway, just east of Grand Avenue, California Highway Patrol Officer Tatiana Saquillo said.
The circumstances of the crash were not immediately clear, she said.
A total of five injured people were taken to hospitals, CHP Sgt. Grady Stephens said.
A helicopter landed in the roadway to fly the injured pregnant woman to the trauma center at Los Angeles County-USC Medical Center, officials said. An update on her condition was not available.
CHP officials issued a Sig Alert for the carpool and four right-hand lanes of the westbound 60 Freeway, leaving only two lanes open for traffic, officials said.
Traffic was backed up all the way to the Police Officer Daniel T. Fraembs Memorial (71) Highway in Pomona shortly after 1 p.m., and significant slowing was also seen on the eastbound lanes of the 60 Freeway near the crash scene.
All traffic lanes were re-opened by 1:30 p.m.
