The area contains a complex patchwork of counties, independent municipalities, and federally significant sites such as the Gateway Arch National Park and Scott Air Force Base, and serves as a regional hub for transportation, manufacturing, and services centered on downtown St. Louis and suburban cores like Clayton, Missouri and Belleville, Illinois.
