According to NBCNewYork, a truck carrying USPS mailboxes was involved in a crash earlier today on Interstate 280 in West Orange, NJ.  The crash caused several of the mailboxes to spill onto the highway.  Fortunately, no one as injured in the crash and the mailboxes were old and empty and were actually being transported to a location where they would be turned into scrap.

This is just the latest instance of something unusual being spilled on a highway.  Last December, money spilled out of a Brinks truck in East Rutherford, NJ.

Last May, chocolate flooded a highway in Poland.

In 2015, a truck filled with bees overturned in Washington.

And in 2017, a truck filled with slime eels crashed in Oregon.
