All lanes on the 60 Freeway were temporarily shut down in both directions at Whittier Boulevard following a small brush fire, the California Highway Patrol said.
The fire broke out underneath the roadway in an embankment just before 10:30 a.m., according to the CHP log.
A SigAlert went into effect at 10:40 a.m. and all lanes on both sides of the freeway were initially closed, the log stated.
Two lanes in each directions were reopened at about 11 a.m., and all eastbound lanes on the roadway were open again shortly after that, the incident log stated.
The westbound lanes on the freeway were reopened just after 11:30 a.m., according to the CHP.
The temporary closures impacted traffic in the area, as a Google Maps traffic map showed vehicles at one point being backed up all the way to the 710 Freeway.
