Marsh Concrete Rainbow Arch Bridge
Marsh Concrete Rainbow Arch Bridge is a reinforced concrete through arch bridge over the Little Cottonwood River in Cambria Township, Minnesota, United States. The bridge is listed on the National Register of Historic Places. The bridge no longer carries traffic, which has since been shifted to another bridge to the east. The bridge was designed by James Barney Marsh James Barney Marsh (April 12, 1856June 26, 1936) was an American engineer and bridge designer. He patented a new design for arch bridges. Marsh gave Archie Alexander, the first African-American to graduate as an engineer from Iowa State Universi ... and built in 1911, the same year in which he filed a patent for his rainbow arch design. His design features two arched ribs, one on either side of the roadway, rising above the deck. The deck is suspended from the arches by vertical risers. Drivers see the rainbow arch crowns on each side, similar to crossing a pony truss bridge. The bridge over the Little Cotton ...

Pony Truss
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. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and the ...

Transportation In Blue Earth County, Minnesota
Transport (in British English), or transportation (in American English), is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land ( rail and road), water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations. Transport infrastructure consists of both fixed installations, including roads, railways, airways, waterways, canals, and pipelines, and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations), and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance. Means of transport are any of the different kinds of transport facilities used to carry people or cargo. They may include vehicles, riding animals, and pack a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
