A crash involving a big rig forced the closure of all but one lane of the westbound 210 Freeway in Pasadena on Thursday morning.
No injuries were reported in the 1:55 a.m. crash on the freeway near Sierra Madre Villa Avenue, according to California Highway Patrol logs.
But a big rig ended up jackknifed across traffic lanes and smashed through a concrete barrier, officials said.
Only the right-hand lane was open to traffic as authorities worked to clear the wreckage. A Sig Alert was cancelled just after 10 a.m.
