The expansion doubles the plant’s size from about 75,000 square feet to 150,000 square feet.
Columbus-based White Castle broke ground for the original 100,000-square-foot facility near Dayton International Airport in the summer of 2012.
Located on 17 acres off U.S. 40 and Peters Pike, the Vandalia plant was designed to produce more than 16,000 hamburgers per hour per production line. The plant opened in late 2013, quickly hiring more than 100 employees in early days.
During last summer’s groundbreaking ceremony, White Castle named the plant “The House That Bill Built” in honor of former president and CEO Bill Ingram, a third-generation family member who served as president from 1980 to 2015 and was responsible for creating and expanding the retail division.
