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 San Bernardino County (), officially the County of San Bernardino, is a County (United States), county located in the Southern California, southern portion of the U.S. state of California, and is located within the Inland Empire area. As of the .... 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorado River
The Colorado River ( es, Río Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern Mexico. The river 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 United States, U.S. National Parks, the Colorado River and its tributaries are a v ...

Atlantic And Pacific Railroad
The Atlantic and Pacific Railroad was a U.S. railroad that owned or operated two disjointed segments, one connecting St. Louis, Missouri with Tulsa, Oklahoma, and the other connecting 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 1849 Pacific Rail ...

Flood Plain
A floodplain or flood plain or bottomlands is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high 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 the regular flooding of floodplains can deposit nutrients and water, floodplains frequently have high soil fertility; some important agricultural regions, such as the Mississippi river basin and the Nile, rely heavily on the flood plains. Agricultural regions as well as urban areas have developed near or on floodplains to take advantage of the rich soil and fresh water. However, the risk of flooding has led to increasing efforts to control flooding. Formation Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Whereve ...

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.

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 that was 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 hing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
