Koch is a former community in St. Louis County, Missouri. It was named for Robert Koch, a German bacteriologist. The location was at what is now Interstate 255 east of Route 231. It had a post office, which is now closed. The Robert Koch Hospital was located just off US 255 before it crosses the Jefferson Barracks Bridge in south county at 4101 Koch Road. The hospital was built by the city of St. Louis primarily as a quarantine facility for patients with a variety of easily transmissible diseases, including smallpox, yellow fever, and tuberculosis. There is a cemetery located on the grounds of this closed hospital, the building founded in 1875 with its last major renovation in 1949 and was demolished in 1989. The cemetery referred to as "Quarantine" cemetery is located on the 503 acres (2.04 km2) associated with this hospital. Many people believe this site is haunted. The hospital site was listed on the National Register of Historic Places in 1984. Nineteen buildings were constructed by 1939 and an 105-acre (0.42 km2) farm, post office, railroad stop, housing, and recreational facilities made the hospital almost self-sustaining. By the end of World War II new medications decreased the life-threatening effects of tuberculosis; from the 1950s to 1983 the hospital was used as housing for the indigent elderly. It also houses an antenna site for St Louis City Emergency Management.

The American Bottom is the flood plain of the Mississippi River in the Metro-East region of Southern Illinois, extending from Alton, Illinois, south to the Kaskaskia River. It is also sometimes called "American Bottoms". The area is about 175 square miles (450 km2), mostly protected from flooding in the 21st century by a levee and drainage canal system. Immediately across the river from St. Louis, Missouri, are industrial and urban areas, but nearby marshland, swamps, and the Horseshoe Lake (which was created by the river) are reminders of the Bottoms' riparian nature. This plain with its rich alluvial soil, served as the center for the pre-Columbian Cahokia Mounds civilization, and later the French settlement of Illinois Country. Deforestation of the river banks in the 19th century to fuel steamboats had dramatic environmental effects in this region. The Mississippi River between St. Louis and the confluence with the Ohio River became wider and more shallow, as unstable banks collapsed into the water. This resulted in more severe flooding and lateral changes of the major channel, causing the destruction of several French colonial towns, such as Kaskaskia, which relocated; Cahokia, and St. Philippe, Illinois. The southern portion of the American Bottoms is primarily agricultural, planted chiefly in corn, wheat, and soybean. The American Bottom is part of the Mississippi Flyway used by migrating birds and has the greatest concentration of bird species in Illinois. The flood plain is bounded on the east by a nearly continuous, 200- to 300-foot high, 80-mile (130 km) long bluff of limestone and dolomite, above which begins the great prairie that covers most of the state. The Mississippi River bounds the Bottom on its west, and the river abuts the bluffline on the Missouri side. Portions of St. Clair, Madison, Monroe, and Randolph counties are in the American Bottom. Its maximum width is about 9 miles (14 km) in the north, and it is about 2 to 3 miles in width throughout most of its southern extent.

Martigney Creek is a stream in St. Louis County in the U.S. state of Missouri. It is a tributary of the Mississippi River. A variant spelling was "Martigne Creek". The creek most likely has the name of Jean B. Martigny, a pioneer landowner.

The Jefferson Barracks Bridge, officially the Jefferson Barracks Memorial Arch Bridge, is a pair of bridges across the Mississippi River on the south side of St. Louis, Missouri metropolitan area. Each bridge is 3,998 feet (1,219 m) long with a 909-foot (277 m) long arch bridge spanning the shipping channel. The northern bridge was built in 1983, and the southern opened in 1992. A delay occurred during the construction of the southern bridge when a crane dropped a section of it into the river and it had to be rebuilt.The original Jefferson Barracks Bridge was a steel truss toll bridge that carried U.S. Route 50. Construction on that bridge began on August 5, 1942, and it opened two years later. A toll was charged until 1959, when the construction bonds were paid off. Prior to the construction of the original bridge, river crossings in this area were made via the Davis Street Ferry in the Carondelet neighborhood of St. Louis.The current bridge carries traffic for both Interstate 255 (part of the St. Louis beltway) and U.S. Route 50. However, I-255 itself was not built until a few years after the northern bridge opened in 1983.The names comes from the nearby Jefferson Barracks National Cemetery, itself originally part of the large Jefferson Barracks military complex, established in 1826 and decommissioned in 1946.

The Jefferson Barracks Military Post is located on the Mississippi River at Lemay, Missouri, south of St. Louis. It was an important and active U.S. Army installation from 1826 through 1946. It is the oldest operating U.S. military installation west of the Mississippi River, and it is now used as a base for the Army and Air National Guard. A Veterans Affairs healthcare system campus is located on the southern portion of the base and is also the headquarters for the Veterans Canteen Service.
