Named for the matriarch of the Kennedy family, the Rose Fitzgerald Kennedy Greenway provides a series of parks above the submerged Central Artery. This replaces the elevated expressway from the 1950s named for Mrs. Kennedy's father, Boston mayor John “Honey Fitz” Fitzgerald. In a recent property transfer, the Massachusetts Turnpike Authority now owns the land, with the private-sector Rose Fitzgerald Kennedy Greenway Conservancy raising funds to maintain the parks and sponsor events. Approximately 75 percent of the thirty-acre, mile-and-a-half-long corridor
Institutional structures will be interspersed among these park units. The parcel north of the North End Parks has been designated for a new YMCA building; to the south will hopefully rise the Boston Museum, designed by Moshe Safdie and Associates to resemble an inverted ship's hull in glass. South of the Wharf District Parks, the New Center for Arts and Culture, a building designed by Daniel Libeskind, will be constructed when fund-raising is completed. Other institutional projects may follow.
