| | Sullivan expanded in size very rapidly during the mid-20th century, its population rising from just 909 in 1920 to 4,098 in 1960. Careful financial management by local business leaders meant it suffered less from the [[Great Depression]] than many other communities, and the completion of U.S. Route 66, following the old railroad route, in the 1920s brought it much prosperity from highway travelers. A small hospital opened in 1962, followed by a radio station, KTUI, in 1966. More recently, the replacement of Route 66 by Interstate 44 has produced another spur in business development, while the downtown section has been the focus of a revitalization project.<ref>http://www.sullivan.mo.us/departments/city_clerk/history/index.php</ref> | | Sullivan expanded in size very rapidly during the mid-20th century, its population rising from just 909 in 1920 to 4,098 in 1960.
