"39th Street, between Twelfth and Eleventh Avenues, looking east, showing a flock of sheep in front of the slaughter house at No. 627, October 31, 1931." West 39th Street near the Hudson River was the center of the city's slaughterhouse district from the middle of the 19th century through the 1950s. Called “Abattoir Row," cattle and other livestock were ferried across the river and held in the slaughterhouses of this neighborhood before being processed for consumption in New York's homes and restaurants. The infrastructure for this operation included a cow tunnel under 12th Avenue for livestock exiting the ferries, and in 1955, an aluminum-sided bridge built above the street so the cattle did not stop the flow of traffic. The pictured block of 39th Street between 11th and 12th Avenues no longer exists, a victim of the Javits Center construction in the late 1970s. Some sources suggest that whatever remained of the cow tunnels were also lost with that development.
