A down escalator leading to the passageway to/from the Jay Street – MetroTech subway complex underneath 370 Jay Street, at Jay Street and Willoughby Street in Downtown Brooklyn. The entrance was built in the 1950s along with the building. The entrance originally included escalators, although I imagine the one pictured is modern.
