"

Columbia is bounded on the west by the Mississippi River. Running in a diagonal line just northeast of Columbia is the border of St. Clair County, beyond which lies Dupo to the north and Millstadt to the east. To the south is Waterloo. Waterloo and Columbia are expected to grow right up to the borders of the other, in effect extending St. Louis's urban sprawl from South St. Louis County across the Jefferson Barracks Bridge into the heart of the formerly rural Monroe County[citation needed].
