A cop stationed on a Brooklyn highway to give out tickets Wednesday morning has become a hero after rescuing a wayward lamb found roaming the Gowanus Expressway.

Officer Dominick Gatto from highway patrol was manning the high occupancy vehicle lane during rush hour when a motorist told him a goat was on the loose.

The animal was first spotted about 9:15 a.m. trotting along the eastbound lanes of the Brooklyn highway near 38th Street and made it all the way to 50th Street, where Gatto was stationed.

The lamb is believed to have escaped from one of the nearby slaughterhouses in Sunset Park and was trying not to become dinner.

Gatto and Lt. Sherif Nassef came to the rescue, chasing down the fearless animal before throwing him in the back of their car when The Post caught up with the trio.

The lucky lamb was transported to an animal rescue on Staten Island, where he will presumably live out the rest of his days in greener pastures.

This is not the first time barnyard animals have terrorized New York’s streets.

The N train in Borough Park had to be temporarily suspended last August when two goats were found roaming the train line and enjoying a nice grass lunch.

It’s believed they’d also escaped the slaughterhouse.

Cops managed to nab the duo after a two-hour operation and the pair were transported to Farm Sanctuary, a nonprofit shelter for farm animals located in Watkins Glen.

Former “The Daily Show” host Jon Stewart, who sits on the board of Farm Sanctuary, was personally on hand to transport the kids.
