Firefighters battled a structure fire in an industrial area of Rosemead.
The three-alarm fire was reported Wednesday in the 2600 block of River Avenue. Video from NewsChopper 4 showed thick plumes of smoke coming from an industrial yard.
The raging flames and thick smoke forced responding crews in defensive mode, pouring water on the conflagration from the exterior and working to prevent the fire from spreading to neighboring structures. The resulting thick smoke wafted into the air to the northeast, across Rosemead Boulevard and toward the San Bernardino (10) Freeway. Both roadways remained open during the firefight.
The fire ultimately went to a third alarm, as more and more crews were summoned to fight the blaze.
