West Mifflin, Pennsylvania in the context of "Roller coaster"

A dead mall, also known as a ghost mall or zombie mall, is a shopping mall that has low consumer traffic or is deteriorating in some manner.

Many malls in North America are considered "dead" when they have no surviving anchor store or successor that could attract people to the mall. Without the pedestrian traffic that department stores previously generated, sales volumes decline for almost all stores and rental revenues from those stores can no longer sustain the costly maintenance of the malls.

Andrew William Mellon (/ˈmɛlən/; March 24, 1855 – August 26, 1937), known also as A. W. Mellon, was an American banker, businessman, industrialist, philanthropist, art collector, and politician. The son of Mellon family patriarch Thomas Mellon, he established a vast business empire before moving into politics. He served as United States Secretary of the Treasury from March 9, 1921, to February 12, 1932, presiding over the boom years of the 1920s and the Wall Street crash of 1929. A conservative Republican, Mellon favored policies that reduced taxation and the national debt of the United States in the aftermath of World War I. Mellon also helped fund and manage Kennywood Park in West Mifflin, Pennsylvania.

Andrew began working at his father's Pittsburgh, Pennsylvania, bank, T. Mellon & Sons, in the early 1870s, eventually becoming the leading figure in the institution. He later renamed T. Mellon & Sons as Mellon National Bank and established another financial institution, the Union Trust Company in Pittsburgh in 1889. By the end of 1913, Mellon National Bank held more money in deposits than any other bank in Pittsburgh, and the second-largest bank in the region was controlled by Union Trust. In the course of his business career, Mellon owned or helped finance large companies including Alcoa, the New York Shipbuilding Corporation, Old Overholt whiskey, Standard Steel Car Company, Westinghouse Electric Corporation, Koppers, the Pittsburgh Coal Company, the Carborundum Company, Union Steel Company, the McClintic-Marshall Construction Company, Gulf Oil, and numerous others. He was also an influential donor to the Republican Party during the Gilded Age and the Progressive Era.
