Fort Belle Fontaine (formerly known as Cantonment Belle Fontaine) is a former U.S. military base located in St. Louis County, Missouri, across the Mississippi and Missouri rivers from Alton, Illinois. The fort was the first U.S. military installation west of the Mississippi, in the newly acquired Louisiana Territory, and served as a starting point for many expeditions to the American West.

The Fort Belle Fontaine County Park is a unit of the park system of St. Louis County, Missouri. 305.6 acres in size, it is bordered by the Missouri River, by Cold Water Creek, and by the Missouri Hills campus of the Missouri Division of Youth Services (M-DYS).The park contains part of the site of Fort Bellefontaine, a fortified post of the United States Army first raised in 1805. The post was visited by Lewis and Clark Expedition upon their return to St. Louis in September 1806. It remained in active service, in two adjacent locations, until 1826. None of the fort remains today. As of 2014, historic markers and signage educated visitors about the vanished post.The fort's location was built up in the 1930s as a parkland development project of the Works Progress Administration. Some WPA facilities remained in use in 2014, and others had evolved into picturesque ruined structures. A three-mile-long nature trail provides access to the creek ravine, WPA masonry, and the site of the vanished fort and trading post. Part of the parkland has been set aside as a reproduction tallgrass prairie, sown with big bluestem grasses and allied species. In the creekbed woods and adjacent uplands can be found the basswood, the burr oak, the chinquapin oak, and other mature-growth species of trees.The park shares a common boundary and entry point with the M-DYS juvenile detention center, and as of 2014 visitors to the park were asked to stop and sign in at a security checkpoint.

The Bellefontaine Bridge is a four-span truss railroad bridge over the Missouri River between St. Charles County, Missouri, and St. Louis County, Missouri. It has four 440-foot (130 m) spans. Construction started on July 4, 1892, and the bridge opened on December 27, 1893.The bridge was built by the Chicago, Burlington and Quincy Railroad and is now owned and operated by BNSF Railway. New Jersey Steel and Iron Company of Trenton, New Jersey, served as the contractor for the original construction, and George S. Morison designed the structure. Notably, the bridge was one of the first to use a Baltimore truss design; the nearby Merchants Bridge (also designed by Morison) used a Pennsylvania through truss design and had opened just a few years prior. The truss spans are found on masonry piers, which were constructed atop caissons founded into bedrock below the river.The structure is the last railroad structure over the Missouri River before its confluence with the Mississippi River.
