. . "Illmo was a community in Scott County, Missouri. Illmo was incorporated into Scott City in 1980.It was next to Scott City. The community was founded in 1905, and its name is a contraction of Illinois and Missouri as the community is near Illinois and in Missouri. The town was created to support a major St. Louis Southwestern and Missouri Pacific railroad hub in the days of steam locomotives. The need for the railroad yard faded as both the railroads combined into Union Pacific."@en .
