New York Central Railroad Yards, April 22, 1931.

The West Midtown Ferry Terminal, operated by the New York Waterway company, is located at Pier 79 on the Hudson River and 39th Street. The terminal's design includes a bus garage and incorporates two of the Lincoln Tunnel's ventilation shafts. The air shafts are constructed of brick in the Art Deco Style. The original terminal, seen here, was built in 1985. An updated design was completed in the mid-2000s after September 11th prompted fears surrounding train travel increased demand for ferry service. The terminal is owned by the New York City but leased to New York Waterway, a private transportation company.

Constructed on the Hudson River Front between 1979 and 1986, the Javits Center is the most contemporary building on our tour. I.M. Pei and Partners designed the conference center to evoke the crystal palaces at the center of 19th-century World’s Fairs in London and Paris. Unfortunately, the Javits Center, has been enmeshed in controversy since its nascence. The project was finished two years behind schedule andmore than $111 million dollars over budget, and was investigated by the U.S. attorney’s office for its links to corrupt, mob-dominated unions. The glass exterior was constructed without any thought to cleaning, and the defining feature of the proposed design, a glittering entrance hall that would have opened onto the Hudson River, was never constructed due to budgetary constraints. In 2015, FXFOWLE completed a major renovation of the Javits Center which greened the building and made the glass façade safer for birds. Javits has been disparagingly likened to a tinker-toy set, a mausoleum, and Darth Vader. New York Times architecture critic Nicolai Ouroussoff went so far as to list the building as one of his “top candidates for demolition” in New York City. With such vitriol surrounding the Javits Center, could a building like this ever warrant historic preservation? Surprisingly, the answer is yes. Historic and cultural significance are accrued over time. Buildings can only be considered for historic designation once they have turned 50, which also happens to be the average lifespan of an American commercial building. A building is most at risk for demolition when it is between 30 and 40 years old. The Javits Center is 34. Should preservationists begin to reconsider the architectural contributions of this building? Probably – I.M. Pei is a significant Chinese-American architect whose work will be studied by many generations to come. With its clear nod to 19th-century architecture, the building embodies many of the ideals of the postmodernism movement and fulfills criteria for cultural significance. Time is the most precious resource in historic preservation – how can we better guess which buildings will be significant before they are at high risk for demolition?

12th Avenue, at the northeast corner of West 34th Street and northeastward. Shown at the corner is a diner under the New York Central Railroad's elevated roadbed. It was completely removed in 1936.

"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.
