A fatal multi-vehicle crash shut down the eastbound 210 Freeway in Pasadena on Friday, triggering a huge traffic backup.
The five-car crash occurred just before 5 p.m. west of Sierra Madre Villa Avenue, according to the California Highway Patrol.
At least one person was killed and two others were injured, the Pasadena Fire Department tweeted.
The freeway was expected to be impacted by the crash for several hours, the CHP stated.
The crash came just hours before the scheduled 55-hour closure of a portion of the westbound 210 Freeway for a $148.5 million pavement rehabilitation project.
The highway will be closed between Lake Avenue on the east end and Mountain Street on the north end, after the 134 splits off to the west, from 10 p.m. Friday through 5 a.m. Monday, according to Caltrans.
The eastbound connection from the 134 Freeway to the westbound 210 will also be shut down during the closure.
