Firefighters were working to extinguish a small trash fire Thursday underneath Interstate 5 in Old Town, officials said.

The fire started around 6:40 a.m. underneath an I-5 bridge near Congress and Mason streets, San Diego Fire-Rescue spokeswoman Monica Munoz said.

Crews arrived at the scene and found trash was on fire under the bridge, Munoz said. The trash was in a compact area and was challenging to fully extinguish.

No injuries were reported and no structures were threatened.

As of 9:25 a.m., no flames were visible, but firefighters remained at the scene and were waiting for Caltrans to arrive and assist with trash removal, Munoz said.

The cause of the fire was under investigation.
