Workers clean up after a semi truck filled with over 400 beehives overturned on Interstate 5 in Lynnwood, Wash. on Friday, April 17, 2015. The truck had just merged onto Interstate 5 around 3:30 a.m. when it tipped on its side, dumping its load of 448 hives, or about 13.7 million bees, Washington State Patrol Trooper Travis Shearer said. The driver was not hurt.  The bees became more active as the sun rose and the weather warmed, and firefighters had to spray a layer of foam on some of the boxes, killing the insects for safety.
