Cahokia Heights, Illinois is a city in St. Clair County, Illinois created by the 2021 merger of the villages of Cahokia (not to be linked), Alorton, and Centreville. Located in the southwestern Illinois portion of the Greater St. Louis metropolitan area, the city lies near the Mississippi River and adjacent to the Missouri border. Cahokia Heights combines suburban, industrial, and historically significant archaeological landscapes, providing connections to regional transportation corridors and cultural institutions.

History

The area now comprising Cahokia Heights is adjacent to the prehistoric Cahokia Mounds State Historic Site, a UNESCO World Heritage Site recognized alongside sites like Mesa Verde National Park and Chaco Culture National Historical Park. European contact in the region involved interactions with the Illinois Confederation and later the French colonial empire in North America, including ties to New France, Pierre Laclède and Antoine de Lamothe Cadillac era expansion. During the 19th century this territory experienced developments related to the Louisiana Purchase, the establishment of St. Clair County, Illinois and riverine commerce on the Mississippi River alongside steamboats like those of the Robert E. Lee (steamboat) era. The 20th century brought industrialization tied to Anheuser-Busch, United States Steel Corporation, and railroad expansions by the Illinois Central Railroad and Missouri Pacific Railroad. Civil rights and urban policy debates in the mid-20th century connected local events to national movements including the Civil Rights Movement and legislation like the Civil Rights Act of 1964. The 2021 municipal consolidation followed precedents in municipal reorganization seen in places such as Nashville, Tennessee (consolidated city–county) and reflected regional governance trends influenced by Metropolitan St. Louis planning and East St. Louis, Illinois redevelopment initiatives.

Geography and climate

Cahokia Heights is situated on the eastern floodplain of the Mississippi River near the confluence with the Missouri River, south of Downtown St. Louis and north of Kaskaskia River tributaries. The city is bounded by interstate and state routes including Interstate 255, Illinois Route 3, and proximity to Interstate 55 and Interstate 64, integrating with Gateway Arch National Park regional access. The topography includes Pleistocene terrace deposits similar to those along the Missouri River valley and alluvial soils comparable to the lower Ohio River basin. Cahokia Heights experiences a humid continental climate characteristic of St. Louis, Missouri, with influences from the Gulf of Mexico that modulate precipitation and severe weather patterns tied to systems tracked by the National Weather Service and historically affected by events such as the Great Flood of 1993 and tornado outbreaks linked to the Super Outbreak of 1974.
