Rock Island Railroad Bridge (Columbia River)
The Rock Island Railroad Bridge is BNSF Railway's bridge across the Columbia River, at Rock Island, Washington. The structure consists of one through truss, one deck truss, and an approach trestle. History The bridge was originally built in 1892 for the Great Northern Railway. Bridging the Columbia River was an important component in completing Great Northern's transcontinental link the following year. The site was chosen at Rock Island, Washington for being the shortest distance between the banks of the Columbia River in Washington state Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington .... In 1925, it was decided to strengthen the main span in anticipation of increased traffic and heavier trains by reinforcing the structure with an additional outside truss frame. and References ...

Columbia River
The Columbia River (Upper Chinook: ' or '; Sahaptin: ''Nch’i-Wàna'' or ''Nchi wana''; Sinixt dialect'' '') is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the U.S. state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven US states and a Canadian province. The fourth-largest river in the United States by volume, the Columbia has the greatest flow of any North American river entering the Pacific. The Columbia has the 36th greatest discharge of any river in the world. The Columbia and its tributaries have been central to the region's culture and economy for thousands of years. They have been used for transportation since a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Island Dam
Rock Island Dam is a hydroelectric dam on the Columbia River, in the U.S. state of Washington. Chelan County Public Utility District's ''Rock Island Dam and Hydro Project'' was the first dam to span the Columbia, having been built from 1929 to 1933. It is located near the geographical center of Washington, about 12 miles (19 km) downstream from the city of Wenatchee. By river, the dam is 235 miles (378 km) south of the Canada–US border and 453 miles (729 km) above the mouth of the river at Astoria, Oregon. The dam's reservoir is called Rock Island Pool.http://pubs.usgs.gov/wdr/2005/wdr-wa-05-1/pdf/wa00103ADR2005_Figure56.pdf Overview Rock Island Dam is constructed on Columbia River basalt similar to that which is exposed on the cliffs near the dam. These columnar basalts were formed from lava flows during the mid- to late-Miocene Epoch, some 14 to 16 million years ago. The rock is strong and durable and provides a very stable foundation for the structure. Columb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railroad Bridges On The National Register Of Historic Places In Washington (state)
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in Track (rail transport), tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on Railroad tie, sleepers (ties) set in track ballast, ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains.

Bridges Over The Columbia River
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rock Island, WA
Rock Island is a city in Douglas County, Washington, United States. It is part of the Wenatchee–East Wenatchee Metropolitan Statistical Area. The population was 788 at the 2010 census. History Rock Island was officially incorporated on November 3, 1930. The area of Rock Island was used by Native American tribes for fishing and crossing of the Columbia River due to the nearby Rock Island Rapids prior to settlement of the Washington Territory. The site had been previously settled in the late 19th century and was known as Hammond; early maps sometimes show the city as Hammond P.O. (Post Office) or Power City. In the teacup valley in which Rock Island is currently located, two men, Ingraham and McBride, opened a trading post in the early 1860s. Their patrons were local Native Americans, who often fished that stretch of the Columbia when the fish were running. The two pioneering men would later move their post to the mouth of the Wenatchee River, leaving little trace of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Senator George Sellar Bridge
The Senator George Sellar Bridge at Wenatchee, Washington was built in 1950 as the "Columbia River Bridge" to carry U.S. Route 2 across the Columbia River. The steel suspended tied-arch bridge has a main span of with anchor arms. The suspended portion of roadway comprises and is wide, carrying five lanes (originally four) with a median divider strip at a height of above mean water level. The new bridge was recognized by the American Institute of Steel Construction as the most beautiful bridge of 1950 for spans over in length. The bridge's engineer was R. W. Finke. The contractor was the General Construction Company of Seattle, using steel fabricated by the American Bridge Company. The bridge rests on two concrete piers in the river, with the central arch between them, and cantilever spans extending to concrete abutments high on the riverbanks. The bridge was renamed in 2000 after George L. Sellar, a Washington state senator who died that year. Since then, the name " Colum ...
