Clark Street Tunnel

The Manhattan side of the Brooklyn Bridge-City Hall stretch starts at a utilitarian grey arch by the East River. Clark Street Tunnel sits mid-block, linking Borough Hall to the subway’s deeper reaches below the river. The station’s 1916 cast‐iron entrances still bear the weight of a century’s commuters moving between Downtown and the Heights.

A single address anchors the entrance: PX2W+4H, New York, NY 10038. A handful of staircases descend to a platform where J and Z trains pause briefly before plunging into the tunnel bored in 1919. Interlocking steel and concrete keep the river at bay, while periodic ventilation shafts add to the occasional down-draft.
