 This produced a number of other visual artifacts; new streets and neighborhoods had to be shoehorned into layouts designed around previously existing features.A number of quirky and archaic labels also remained, such as ""The Shed"", a large disused building on Pier 42 on the East River, and Mussel Island, a long-gone feature of Newtown Creek.In 2002, Hagstrom switched to all-digital master maps using more conventional layouts and labels.
