Two transition roads at the Ventura (134) and Foothill (210) freeways in Pasadena were closed early Monday after a big-rig jackknifed on a slick roadway, sending one trailer and cab down an embankment.
The crash was reported to the California Highway Patrol shortly after 2 a.m., said Officer Patrick Kimball. The transition road may be closed until 11 a.m., officials said.
