Fire rescue officials said they were called to the scene at 3:03 p.m.

The Florida Highway Patrol said the box truck was traveling northbound on I-95 when it left the road to the right. The truck then started rotating counter-clockwise and traveled across all lanes of traffic, running off the road to the left.

FHP said the truck then struck the guardrail and bridge support.

A viewer told Action News Jax that one person was killed and a second person was badly burned in the crash.

"I pull up. I see it. The whole passenger side is engulfed," witness Anthony Jackson said. "People are frantically trying to run back and forth using fire extinguishers and I believe, what I found out later, was water bottles."

He said the scene was horrific.

"The passenger side was completely engulfed. Like completely engulfed, crushed. It was bad," Jackson said. "I mean, sitting there watching a man burn to death thinking nobody else can do anything. You can’t get too close to try to tell the man, you’re going to be okay."

The crash initially shut down I-95 in both directions.

FDOT officials said a crew will inspect the overpass for signs of structural damage after first responders clear the area.
