PASADENA (CNS) - One person was killed and two others injured in an  underground six-vehicle crash on the eastbound Foothill (210) Freeway in  Pasadena early today, and a second motorist was killed on the same freeway less  than three hours later, authorities said.

Three big rigs and three other vehicles were involved in the first  wreck, said California Highway Patrol dispatch officer A. Rubio, adding that a  50-year-old man died at the scene.

A Pasadena Fire Department commander told a videographer at the scene  that the deceased was the driver of the lead big rig in the wreck. He said the  big rig jackknifed, with the cab and trailer separating.

Two people were taken from the site to a hospital, the fire commander  said.

The accident occurred around on the two-lane underground  transition from the eastbound 210 to the eastbound Ventura (134) Freeway,  resulting in the closure of the eastbound 210 and traffic being diverted to the  westbound 134, Rubio said.

A second big rig fatality, this one reported at 2:57 a.m, about four  miles east on the eastbound 210, prompted the closure of the Metro Gold Line  between Pasadena's Allen and Sierra Madre Villa stations, Metro spokeswoman Kim  Upton said.

Debris from the second accident, in which a big rig struck the freeway  center divider, killing a 33-year-old truck driver from MorenoValley, littered  the adjoining Gold Line tracks, which run down the center of the freeway. Both  the body and the big rig's trailer ended up on the track, according to the CHP.

Service between the two stations, which normally starts at was  stopped, Upton said. Trains were replaced by a bus bridge to help Gold Line  passengers around the shuttered stretch of track. Upton said the shuttle  service will run every 20 minutes between the stations until the track is  reopened.
