It’s a former trolley terminal Trolleys? Yes, trolleys. NYC was once a very trolley-centric city, with many trolley lines from Brooklyn coming over the Williamsberg bridge and terminating here in this terminal. The terminal opened shortly after the bridge, in 1904. Service ended in 1948 – at which time the terminal was simply left abandoned.
Today, the terminal is being eyed as a potential new park. This seemingly unlikely location for a park would create a very unique underground experience driven in part by technology. One can only hope they keep some historic reference to the terminal’s former life in the new designs.
