The Mississippi River is the primary river, and second-longest river, of the largest drainage basin in the United States. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for 2,340 miles (3,766 km) to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is 1,151,000 sq mi (2,980,000 km2), of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements, typically straight, may be stressed from tension, compression, or sometimes both in response to dynamic loads. There are several types of truss bridges, including some with simple designs that were among the first bridges designed in the 19th and early 20th centuries. A truss bridge is economical to construct primarily because it uses materials efficiently.
The Illinois Central Railroad, sometimes called the Main Line of Mid-America, was a railroad in the Central United States, with its primary routes connecting Chicago, Illinois, with New Orleans, Louisiana, and Mobile, Alabama, and thus, the Great Lakes to the Gulf of Mexico. A line also connected Chicago west to Sioux City, Iowa (1870). There was a significant branch to Omaha, Nebraska (1899), west of Fort Dodge, Iowa, and another branch reaching Sioux Falls, South Dakota (1877), starting from Cherokee, Iowa. The IC also serviced Miami, Florida, on trackage owned by other railroads.
The Hennepin Canal State Trail, also just called the Hennepin Canal, is an abandoned waterway in northwest Illinois, between the Mississippi River at Rock Island and the Illinois River near Hennepin. The entire canal is listed on the National Register of Historic Places.
The McKinley Bridge is a steel truss bridge across the Mississippi River. It connects northern portions of the city of St. Louis, Missouri with Venice, Illinois. It opened in 1910 and was taken out of service on October 30, 2001. The bridge was reopened for pedestrian and bicyclists on November 17, 2007 with a grand re-opening celebration. Since December 2007, McKinley has been open to vehicular traffic as well. It is accessible from Illinois Route 3 in Illinois and from the intersection of Salisbury and North 9th Street in the city of St. Louis. The bridge carried both railroad and vehicular traffic across the Mississippi River for decades. By 1978, the railroad line over the span was closed, and an additional set of lanes was opened for vehicles in the inner roadway.
The MacArthur Bridge is a truss bridge that connects St. Louis, Missouri and East St. Louis, Illinois over the Mississippi River. The bridge was initially called the "St. Louis Municipal Bridge" and known popularly as the "Free Bridge" due to the original lack of tolls. Tolls were added for auto traffic beginning in 1932. In 1942, the bridge was renamed for Douglas MacArthur. The bridge was constructed to break the monopoly of the Terminal Railroad Association, which controlled two other bridges at St. Louis and charged what were viewed as unreasonable tolls.
The Industrial Canal is a 5.5 mile (9 km) waterway in New Orleans, Louisiana, United States. The waterway's proper name, as used by the U.S. Army Corps of Engineers and on NOAA nautical charts, is Inner Harbor Navigation Canal (IHNC). The more common "Industrial Canal" name is used locally, both by commercial mariners and by landside residents.
Forgottonia, also spelled Forgotonia, is the name given to a 16-county region in Western Illinois in the late 1960s and early 1970s. This geographic region forms the distinctive western bulge of Illinois that is roughly equivalent to "The Tract", the Illinois portion of the Military Tract of 1812, along and west of the Fourth Principal Meridian. Since this wedge-shaped region lies between the Illinois and Mississippi rivers, it has historically been isolated from the eastern portion of Central Illinois.
The Wabash Bridge carries one railroad track across the Mississippi River between Hannibal, Missouri, and Pike County, Illinois. Built by the Wabash Railroad, the bridge is today owned by the Norfolk Southern Railway.
The Keokuk Bridge, also known as the Keokuk Municipal Bridge, is a double-deck, single-track railway and highway bridge across the Mississippi River in the United States between Keokuk, Iowa, and Hamilton, Illinois, just downstream of Mississippi Lock and Dam number 19. It was designed by Ralph Modjeski and constructed 1915–1916 on the piers of its predecessor that was constructed in 1869–1871.
The Burlington Bridge is a vertical-lift railroad bridge across the Mississippi River between Burlington, Iowa, and Gulfport, Illinois, United States. It is currently owned by BNSF Railway and carries two tracks which are part of BNSF's Chicago–Denver main line.
The Crescent Bridge carries a rail line across the Mississippi River between Davenport, Iowa and Rock Island, Illinois. It was formerly owned by the Davenport, Rock Island and North Western Railway, a joint subsidiary of the Chicago, Burlington and Quincy Railroad and Chicago, Milwaukee, St. Paul and Pacific Railroad, which was split in 1995 between then-joint owners Burlington Northern Railroad and Soo Line Railroad, with BN getting the bridge and the Illinois-side line, and Soo Line getting the Iowa-side line. Since then, after spinning off its lines in the area to I&M Rail Link, later Iowa, Chicago and Eastern Railroad, the lines were repurchased by the Canadian Pacific Railway, parent of the Soo Line. Meanwhile, BN has merged into the BNSF Railway, the current owner of the bridge.
The Government Bridge or Arsenal Bridge spans the Mississippi River, connecting Rock Island, Illinois and Davenport, Iowa. The Iowa Interstate Railroad uses the upper deck of the bridge for its ex-Chicago and Rock Island Railroad route between Council Bluffs, Iowa and Chicago, Illinois. The lower deck carries automobile traffic between the two cities. It is located near Upper Mississippi Mile Marker 483, adjacent to the Mississippi River Lock and Dam No. 15. The current structure is the fourth at this location. The bridges all were built with a swing section to accommodate traffic navigating the river.
The Clinton Railroad Bridge, also called the Chicago and Northwestern Railway Bridge or more simply the Clinton Bridge, is a bridge that carries double tracked rail lines across the Mississippi River between Clinton, Iowa, and Fulton (Albany), Illinois. The bridge is a truss bridge with a swing span crossing the main river channel and is adjacent to the Gateway Bridge. The original bridge was constructed in 1858, and the first train crossed the bridge on January 19, 1860. The bridge was the second railroad crossing over the Mississippi River. In 1870, the bridge was declared a post route, therefore stopping the occupation of steamboats and approval of railroads. From 1859 to 1908, the mileage in operation increased from 28,789 to 229,230, prompting the Chicago and North Western Railway to replace the bridge with a new structure in 1900.
The La Crosse Rail Bridge is a swing bridge that spans the Mississippi River between La Crescent, Minnesota and La Crosse, Wisconsin. The first bridge in this location initially was designed and ready to build by June 1876, and was completed in November 1876 by the Milwaukee and St. Paul Railway, a predecessor of the Chicago, Milwaukee, St. Paul and Pacific Railroad. It was later replaced in 1902. It is at the Western end of the Canadian Pacific Railway Tomah Subdivision. Amtrak's Empire Builder crosses this bridge.
Hastings Rail Bridge is a vertical-lift bridge that spans the Mississippi River in Hastings, Minnesota. It is one of only four lift spans on the Mississippi River, the others being at Hannibal, Missouri, Burlington, Iowa and in downtown St. Paul, Minnesota. It was built in 1981 by Milwaukee Road and was designed by Howard, Needles, Tammen & Bergendoff.
St. Paul Union Pacific Rail Bridge, also known as the Hoffman Swing Bridge, is a swing bridge that spans the Mississippi River between South Saint Paul, Minnesota and Saint Paul, Minnesota in the United States. It was built in 1910 by the St. Paul Bridge and Terminal Railway, and was rebuilt in 1925, after a flood in 1951, and again in 1982.
The Canal Street railroad bridge is a vertical-lift bridge across the south branch of the Chicago River in Chicago, Illinois. It was designated a Chicago Landmark on December 12, 2007.
Waddell & Harrington was an American engineering company that designed bridges from 1907 to 1915. It was formed in 1907 as a partnership of John Alexander Low Waddell (1854–1938) and John Lyle Harrington (1868–1942) and was based in Kansas City, Missouri, but had offices in Portland, Oregon, and Vancouver, British Columbia. The company designed more than 30 vertical-lift bridges for highways and railroads.
