3. Trump Golf Links at Ferry Point

Construction of the Second Avenue Subway churned out 5,000 tons of rock a day. The rock that workers tunneled through to build the subway line was Manhattan schist, a rock that is twice as hard as concrete. Manhattan Schist can be found in many buildings in New York City like the campus of the City College of New York. After being bored through and ground up, schist is referred to as “mole rock,” a useful and inexpensive building material.

One of the locations that received “mole rock” from the Second Avenue Subway tunnels is Trump Golf Links at Ferry Point, a golf course in the Bronx which opened in 2013. The course, designed by Jack Nicklaus with views of the New York skyline, used nearly half of the mole rock from the Second Avenue Subway project.

St. Peter’s University in Jersey City was another recipient of the debris extracted during construction of the second avenue subway, receiving 70,000 tons of mole rock which was to be used to build a new dormitory. The new dormitories were part of a 21-story mixed-use tower designed by KPN architects, but construction on the project has yet to begin.
