Pier 57, at 15th Street and 11th Avenue, formerly served as a terminal for shipping and storage of cargo for the Grace Line. Between 1969 and 2003, Pier 57 housed the Hudson Pier Bus Depot for the New York City Transit Authority. Since then, it has been designated for commercial development. During the 2004 Republican National Convention protests, the New York City Police Department used Pier 57 as a makeshift jail to hold people arrested during protests related to the convention. The holding pens were dubbed "Guantanamo on the Hudson" by activists and in the media. Various lawsuits were filed against the city related to conditions at the site and allegedly illegal arrests, including those of bystanders. Plans created in 2009 call for an improved pier design for commercial use, dubbed the SuperPier, which was slated to be completed in 2019.
