A brush fire along the side of the 91 Freeway sent smoke wafting over lanes as crews battled the flames this afternoon.

CHP dispatch records showed the blaze started around 11:45 a.m. and had ignited a large tree near the Long Beach Boulevard off-ramp. Video from the scene shows cars slowly maneuvering through the smoke as firefighters worked nearby.

The flames charred between 3 and 5 acres of vegetation, according to LBFD spokesman Brian Fisk. Crews had the flames doused by 1 p.m. but still had extensive mop-up to perform after that.

Fisk said it didn’t appear any structures were ever threatened by the blaze, and nobody was hurt. It wasn’t immediately clear how the fire started.

The bulk of the fire appeared to have been burning in Long Beach’s city limits, but Los Angeles County and Compton fire crews were also assisting, Fisk said.
