Plumes of thick, white smoke rose above Kearny Mesa Tuesday evening as crews rushed to put out a fire at a commercial building.
The fire broke out around 6:55 p.m. inside a cardboard recycling center near Convoy and Vickers streets off Balboa Avenue, according to the San Diego Fire-Rescue Department (SDFD).
The building is just a few blocks from State Route 163 and State Route 52.
Smoke from the rubbish fire could be seen for miles as crews arrived on the scene, and a helicopter worked overhead.
Several nearby roads were shut down as crews worked to extinguish the fire.
The fire department called for a second-alarm because crews were worried the fire would spread.
At least 60 firefighters were on scene, battling the flames.
At approximately 11 p.m., crews were still on scene to make sure the fire did not reignite.
There were no injuries, fire officials said.
