LowLine

The Lowline, formerly known as the Delancey Underground, is a stalled construction project that would have become the world's first underground park in the New York City borough of Manhattan. It is located under the eastbound roadway of Delancey Street on the Lower East Side, in the former Williamsburg Bridge Trolley Terminal adjacent to the Essex Street station and the Essex Crossing complex. Construction of the Lowline began in 2019, but was put on hold in 2020 due to lack of funds.
