Two Floral Park firefighters were injured when their truck hit a bridge pillar as they were responding to a building fire.
The wreck happened near the Long Island Rail Road overpass, according to News12.
One of the firefighters was transported to the hospital.
They were headed to assist at a basement fire in a commercial business.
Conditions were too dangerous for firefighters to stay inside, so they fought the flames and smoke from the street.
"Basement fires are always the most challenging for any fire department. Usually it's one way in and one way out, which makes it very dangerous," Nassau County Chief Fire Marshal Michael Uttaro told reporters, adding that 125 firefighters from 17 departments responded.
The fire destroyed a half dozen businesses. Three firefighters were injured at the scene.
