Hematite is a station on the Liberty City Subway system. It is located in the pedestrian promenade of Golden Pier in The Meat Quarter in western Algonquin, Liberty City. Additional entrances can be found on Union Drive West, just north of its intersection with Hematite Street. In addition to Golden Pier, the stop offers convenient acess to Rotterdam Tower, only two blocks to the east (though nearby Suffolk station in its namesake neighborhood is much closer). The station is served by the A/J Algonquin Outer Line.
