To grasp St. Charles County’s dramatic growth, one only needs to view two photos taken 47 years apart by Jim Karll.
Both show Highway K in O’Fallon, just south of Interstate 70. The first photo, taken in 1970, shows a remote road amid farmland and woods. In the second, Highway K is packed with traffic and flanked by shopping centers and businesses.
St. Charles County’s population skyrocketed from 90,000 in 1970 to almost 400,000 today — a pace unmatched anywhere else in the state. It also has the second-largest bloc of GOP voters in the state and attracts lots of businesses. But a few things threaten its upward trajectory, namely public transportation and a lack of diversity.
