Greenwich Bay in Warwick is located southwest of Warwick Neck, about 10 miles south of Providence. Greenwich Cove is the small inlet at the southwestern end of Greenwich Bay that is bordered on the east by Goddard State Park in Warwick and on the west by the Warwick-East Greenwich waterfront. Greenwich Cove is used by fishing and recreational craft.
The project, completed in 1891, consists of a 500-foot-long channel through the sand bar at the entrance to Greenwich Cove, west of Long Point. The channel, 10 feet deep and 210 feet wide, provides access to the Warwick-East Greenwich waterfront.
