Sig Alert, 60 Freeway, Glen Avon 4:14 a.m.

A Fedex tractor trailer jackknifed and overturned on the westbound 60 Freeway this morning, prompting a Sig Alert and the closure of several lanes.
The semi jackknifed into the right shoulder wall at Pyrite Street at 4:14 a.m., blocking three lanes. Traffic backed up more than two miles while crews offloaded the overturned trailer so it could be tipped back onto its wheels. By 8:38 a.m., all but the slow lane had been reopened.
