The Bronx Bombers (missiles in the bronx?)

I just found this story, not much information on it... why are there missiles driving through the bronx? Is there some sort of military missile battery they could be re-supplying or loading ships? Any thoughts?

NEW YORK (Reuters) - A missile fell off a truck and onto a New York highway on Friday, but the weapon did not have a warhead and posed no danger, police said.

WCBS radio reported it was a Tomahawk cruise missile. Police and fire department officials could not confirm that.

The cargo came loose when the truck carrying it collided with another truck on a motorway in the Bronx.

"It was a military-type missile but it was inert. There was no danger and no one was harmed," a police spokesman said.

Friday night I met a guy who was stuck in traffic behind that. He took some pictures of the missile. He said he missed a flight to a wedding and there was no way anyone was going to believe the reason for the traffic.
