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.

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.
