A swing bridge is a movable bridge that can be rotated horizontally around a vertical axis. It has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span can then pivot horizontally as shown in the animated illustration to the right.
The Chicago, Burlington and Quincy Railroad was a railroad that operated in the Midwestern United States. Commonly referred to as the Burlington Route, the Burlington, CB&Q, or as the Q, it operated extensive trackage in the states of Colorado, Illinois, Iowa, Missouri, Nebraska, Wisconsin, Wyoming, and also in Texas through subsidiaries Colorado and Southern Railway, Fort Worth and Denver Railway, and Burlington-Rock Island Railroad. Its primary connections included Chicago, Minneapolis–Saint Paul, St. Louis, Kansas City, and Denver. Because of this extensive trackage in the midwest and mountain states, the railroad used the advertising slogans "Everywhere West", "Way of the Zephyrs", and "The Way West".
The BNSF Railway Bridge 5.1, also known as the St. Johns Railroad Bridge or the Willamette River Railroad Bridge, is a through truss railway bridge with a vertical lift that spans the Willamette River in Portland, Oregon, United States. Built by the Spokane, Portland and Seattle Railway (SP&S) and completed in 1908, it was originally a swing-span bridge, and its swing-span section was the longest in the world at the time. However, 81 years later the main span was converted from a swing-type to a vertical-lift type, in order to widen the navigation channel. The lift span is one of the highest and longest in the world. The bridge consists of five sections, with the two sections closest to the bank on each side fixed.
The Fort Madison Toll Bridge is a tolled, double-decked swinging truss bridge over the Mississippi River that connects Fort Madison, Iowa, and unincorporated Niota, Illinois. A double-track railway occupies the lower deck of the bridge, while two lanes of road traffic are carried on the upper deck. The bridge is about 1 mile (1.6 km) long with a swing span of 525 feet (160 m), and was the longest and largest double-deck swing-span bridge in the world when constructed in 1927. It replaced an inadequate combination roadway/single-track bridge completed in 1887. The main river crossing consists of four 270-foot (82 m) Baltimore through truss spans and a swing span made of two equal arms, 266 feet (81 m) long. In 1999, it was listed in the National Register of Historic Places under the title, Fort Madison Bridge, ID number 99001035. It was also documented as survey number IA-62 by the Historic American Engineering Record, archived at the Library of Congress. Construction and photographic details were recorded at the time in Scientific American magazine.
The Frisco Bridge, previously known as the Memphis Bridge, is a cantilevered through truss bridge carrying a rail line across the Mississippi River between West Memphis, Arkansas, and Memphis, Tennessee.
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 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 Armour-Swift-Burlington (ASB) Bridge, also known as the North Kansas City Bridge and the LRC Bridge, is a rail crossing over the Missouri River in Kansas City, Missouri, that formerly also had an upper deck for automobile traffic.
The Sibley Railroad Bridge is a three-span through truss single-track railroad bridge belonging to the BNSF Railway between Jackson County, Missouri, and Ray County, Missouri, at Sibley. The bridge carries the BNSF Marceline Subdivision over the Missouri River. It is the only single-track segment of the subdivision. The original 1887–88 bridge was a three-span Whipple through truss and was later reconstructed with Parker through truss spans. Besides the freight trains of BNSF Railway, it is also used by Amtrak's Southwest Chief.
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 Minneapolis Great Northern Depot, also known as Great Northern Station, was a passenger railroad station which served Minneapolis, Minnesota, USA. It was built in 1913 and demolished in 1978. It was located on Hennepin Avenue next to the Hennepin Avenue Bridge and across the street from the main Minneapolis Post Office.
Burlington Northern Railroad Bridge 9.6 or BNSF Railway Bridge 9.6, also known as the Columbia River Railroad Bridge, is through truss railway bridge across the Columbia River, between Portland, Oregon, and Vancouver, Washington, owned and operated by BNSF Railway. Built by the Spokane, Portland and Seattle Railway (SP&S) and completed in 1908, it was the first bridge of any kind to be built across the lower Columbia River, preceding the first road bridge, the nearby Interstate Bridge, by a little more than eight years.
Crossing the Kansas River in Kansas City, Kansas, the Highline Bridge is rare example of a double-tracked, double-deck railroad bridge designed for carrying railroad traffic on both levels. The bridge is owned and operated by the Kansas City Terminal Railway (KCTR) and provides access between the extensive rail yards on both sides of the river in the Argentine and Armourdale neighborhoods in Kansas City, Kansas and other rail yards in Kansas City, Missouri.
The Metropolis Bridge is a railroad bridge which spans the Ohio River at Metropolis, Illinois. Originally built for the Chicago, Burlington and Quincy Railroad, construction began in 1914 under the direction of engineer Ralph Modjeski.
The St. Croix Subdivision or St. Croix Sub is an American rail line operated by the BNSF Railway.

It runs through the communities of La Crosse, Onalaska, Brice Prairie, Trempealeau, East Winona, Fountain City, Cochrane, Buffalo City, Alma, Nelson, Pepin, Stockholm, Maiden Rock, Bay City, Diamond Bluff, and Prescott, Wisconsin. This section of track sees 55-60 trains a day and is double tracked for most of the 150 miles with exceptions of Burns to Prescott, Mears to Trevino, and Winona Jct. to East Winona. The BNSF vertical lift bridge over the mouth of the St. Croix river is single-tracked.
The Burlington, Cedar Rapids and Northern Railway (BCR&N) was a railroad that operated in the United States from 1876 to 1903. It was formed to take over the operations of the bankrupt Burlington, Cedar Rapids and Minnesota Railway, which was, in turn, the result of merging several predecessor lines, the construction of which began in 1869. The corporate headquarters were in Cedar Rapids, Iowa, and it had operations in Iowa and in Minnesota. It was succeeded by the Chicago, Rock Island and Pacific Railway.
The Alton Bridge was a railroad bridge that carried the Chicago, Burlington, and Quincy across the Mississippi River between West Alton, Missouri, and Alton, Illinois. It was located 100 yards (91 m) upriver from, and parallel to, the Old Clark Bridge. The bridge was built between 1892 and 1894 and was removed shortly after the line was abandoned in 1988. With a total length of 2,060 feet (630 m), it consisted of eight through-truss segments—six Pratt trusses, one Pennsylvania truss, and one pivot-swinging truss.
The California Zephyr is a long-distance passenger train operated by Amtrak between Chicago and the San Francisco Bay Area, via Omaha, Denver, Salt Lake City, and Reno. At 2,438 miles (3,924 km), it is Amtrak's longest daily route, and second-longest overall after the Texas Eagle's triweekly continuation from San Antonio to Los Angeles, with travel time between the termini taking approximately 511⁄2 hours. Amtrak claims the route as one of its most scenic, with views of the upper Colorado River valley in the Rocky Mountains, and the Sierra Nevada. The modern train is the second iteration of a train named California Zephyr; the original train was privately operated and ran on a different route through Nevada and California.
