The populated areas of the city are located between Lambert-Saint Louis International Airport and St. Charles. The Missouri River serves as the city's northwestern boundary. It is centered at 38°45'26" North, 90°25'4" West (38.7573, -90.4179).
The area has long been influenced by its proximity to important local transportation routes, dating back to Native American trails established by the Osage Nation. Many of those trails served as the routes for the first roads in the area, such as Natural Bridge and the historic St. Charles Rock Road, which date back to the days of Spanish, French, and early American settlement. The influence continues today, with the recreational American Discovery Trail passing through the area, and the intersection of I-70 and I-270 adding to air and rail access to make the area a good base for transportation-dependent industries.
