Eastbridge, Arizona
Eastbridge was a railroad station on the east bank of the Colorado River in Mohave County, Arizona, United States. It was located at the site of the first bridge the Atlantic and Pacific Railroad built across that river, three miles southeast of Needles, in San Bernardino County, California. History The wooden bridge across the Colorado River constructed between Eastbridge station and the California bank in 1883 was built across the wet alluvial soils of the flood plain of the Mohave Valley. The site had no solid base on either bank and was over 1600 feet wide. The construction was conducted during the flood season of the Colorado that began in May. For three months, the building crews struggled to drive wooden pilings into the river bed only to see them washed out by the river. Pilings were only driven into the mid river section with the help of a pile driver mounted on Barge No. 3, towed and held in position by the ''Mohave II''. This first bridge, when completed in Augu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorado River
The Colorado River () is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and in northern Mexico. The river, the List of longest rivers of the United States (by main stem), 5th longest in the United States, drains an expansive, arid drainage basin, watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the Mexico–United States border, international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora. Known for its dramatic canyons, whitewater rapids, and eleven National parks of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atlantic And Pacific Railroad
The Atlantic and Pacific Railroad was an American railroad that owned or operated two individual segments of track. One connected St. Louis, Missouri, with Tulsa, Oklahoma, and the other connected Albuquerque, New Mexico, with Needles in Southern California. It was incorporated by the U.S. Congress in 1866 as a transcontinental railroad connecting Springfield, Missouri, and Van Buren, Arkansas, with California. The central portion was never constructed, and the two halves later became parts of the St. Louis-San Francisco Railway and Atchison, Topeka and Santa Fe Railway systems, now both merged into the BNSF Railway. History The A&P's earliest predecessor was the Pacific Railroad, incorporated by the Missouri General Assembly in 1849 to connect St. Louis and a point south of Kansas City across the center of the state. In response to an 1852 federal law granting public lands to Missouri to aid in constructing two cross-state railroads, the state approved an amendment to the 1 ...

Needles was named after The Needles (Arizona), "The Needles", a group of Pinnacle (geology), pinnacles in the Mohave Mountains on the Arizona side of the river. The crossing was a poor site for a bridge, lacking firm banks and a solid bottom. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flood Plain
A floodplain or flood plain or bottomlands is an area of land adjacent to a river. Floodplains stretch from the banks of a river channel to the base of the enclosing valley, and experience flooding during periods of high Discharge (hydrology), discharge.Goudie, A. S., 2004, ''Encyclopedia of Geomorphology'', vol. 1. Routledge, New York. The soils usually consist of clays, silts, sands, and gravels deposited during floods. Because of regular flooding, floodplains frequently have high soil fertility since nutrients are deposited with the flood waters. This can encourage farming; some important agricultural regions, such as the Nile and Mississippi Basin, Mississippi Drainage basin, river basins, heavily exploit floodplains. Agricultural and urban regions have developed near or on floodplains to take advantage of the rich soil and freshwater. However, the Flood risk, risk of inundation has led to increasing efforts to Flood control, control flooding. Formation Most floodplai ...

Red Rock Bridge
The Red Rock Bridge was a bridge across the Colorado River at Topock, Arizona, Topock, Arizona that carried the Atlantic & Pacific Railroad. It was built in 1890, replacing a wooden bridge dating to 1883 that was repeatedly washed out during spring flooding. It was used by the railroad until 1945 when a new bridge was built. The Red Rock Bridge was then converted to carry the automobile traffic of U.S. Route 66, and did so from 1947 until 1966 when Route 66 traffic was directed onto the Interstate 40 bridge. At that time the Red Rock Bridge was abandoned, and it was eventually dismantled in 1976. History In 1880, the Atlantic & Pacific railroad's Western division began construction of a line from Isleta, New Mexico, heading west to meet the Southern Pacific Transportation Company, Southern Pacific at Needles, California, on the western bank of the Colorado just north of Topock. The Southern Pacific was simultaneously building eastward from Mohave, California, to Needles. The li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cantilever Bridge
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers). For small footbridges, the cantilevers may be simple beam (structure), beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete. The steel truss cantilever bridge was a major engineering breakthrough when first put into practice, as it can span distances of over , and can be more easily constructed at difficult crossings by virtue of using little or no falsework. Origins Civil engineer, Engineers in the 19th century understood that a bridge continuous across multiple supports would distribute the loads among them. This would result in lower stresses in the girder or truss and meant that longer spans could be built. Several 19th-century engineers patented continuous bridges with hinge points mid-span. The use of a hinge in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
