Fallen canisters cause closure of Nashville ramp

NASHVILLE, Tenn. -- Canisters of frozen bull semen that fell from a Greyhound bus caused a minor scare when emergency officials found them emitting vapor by the side of the road near downtown Nashville.

The canisters fell off just before 6 a.m. on Tuesday as the bus traveled around the curve of a ramp to Interstate 65. Metro Nashville police and fire officials were called to the scene because of reports of a foul odor coming from the leaking canisters.

WKRN-TV reported the four canisters of sperm and dry ice were en route from Ohio to a Texas breeding facility.

Officials shut down the ramp until they determined what was in the containers, but the scene was cleared around 9 a.m.
