About East Alton

East Alton is a village in Madison County, Illinois, United States. The population was 5,786 at the 2020 census, down from 6,301 in 2010. == History == East Alton was incorporated as a village in 1893 (some say 1894). William Cobb, namesake of Cobb Street, was one of the first mayors, from 1895 to 1896, and again in 1902–1905. Like many River Bend communities, the town dates back to when European settlers came to the area in the early 19th century.
