St. Charles Air Line Bridge
The St. Charles Air Line Bridge is a Strauss Trunnion bascule bridge which spans the Chicago River in Chicago, Illinois. Built as part of the St. Charles Air Line Railroad by the American Bridge Company in 1919, the bridge originally had a span of . This bridge held the world record for longest bascule-type span until 1930, when it was shortened to during a relocation as a result of straightening the river channel. The chief design engineer of the original bridge was Leonard O. Hopkins.

Grand Central Station (Chicago)
Grand Central Station was a passenger railroad terminal in downtown Chicago, Illinois, from 1890 to 1969. It was located at 201 West Harrison Street on a block bounded by Harrison, Wells and Polk Streets and the Chicago River in the southwestern portion of the Chicago Loop. Grand Central Station was designed by architect Solon Spencer Beman for the Wisconsin Central Railroad (WC), and was completed by the Chicago and Northern Pacific Railroad. The Baltimore and Ohio Railroad purchased the station in 1910 and used it as the Chicago terminus for its passenger rail service, including its ''Capitol Limited'' service to Washington, D.C. Major tenant railroads included the Soo Line Railroad, successor to the Wisconsin Central, the Chicago Great Western Railway, and the Pere Marquette Railway. The station opened December 8, 1890, closed November 8, 1969, and was demolished in 1971. Construction In October 1889, a subsidiary of the Wisconsin Central Railroad began constructing a ...

Canadian National Railway
The Canadian National Railway Company (french: Compagnie des chemins de fer nationaux du Canada) is a Canadian Class I freight railway headquartered in Montreal, Quebec, which serves Canada and the Midwestern and Southern United States. CN is Canada's largest railway, in terms of both revenue and the physical size of its rail network, spanning Canada from the Atlantic coast in Nova Scotia to the Pacific coast in British Columbia across approximately of track. In the late 20th century, CN gained extensive capacity in the United States by taking over such railroads as the Illinois Central. CN is a public company with 22,600 employees, and it has a market cap of approximately CA$90 billion. CN was government-owned, having been a Canadian Crown corporation from its founding in 1919 until being privatized in 1995. , Bill Gates is the largest single shareholder of CN stock, owning a 14.2% interest through Cascade Investment and his own Bill and Melinda Gates Foundation.

Chicago River
The Chicago River is a system of rivers and canals with a combined length of that runs through the city of Chicago, including its center (the Chicago Loop). Though not especially long, the river is notable because it is one of the reasons for Chicago's geographic importance: the related Chicago Portage is a link between the Great Lakes and the Mississippi River Basin, and ultimately the Gulf of Mexico. The river is also noteworthy for its natural and human-engineered history. In 1887, the Illinois General Assembly decided to reverse the flow of the Chicago River through civil engineering by taking water from Lake Michigan and discharging it into the Mississippi River watershed, partly in response to concerns created by an extreme weather event in 1885 that threatened the city's water supply. In 1889, the Illinois General Assembly created the Chicago Sanitary District (now the Metropolitan Water Reclamation District) to replace the Illinois and Michigan Canal with the Chica ...

Bascule Bridge
A bascule bridge (also referred to as a drawbridge or a lifting bridge) is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed. The name comes from the French term for balance scale, which employs the same principle. Bascule bridges are the most common type of movable span because they open quickly and require relatively little energy to operate, while providing the possibility for unlimited vertical clearance for marine traffic. History Bascule bridges have been in use since ancient times, but until the adoption of steam power in the 1850s, very long, heavy spans could not be moved quickly enough for practical application. Types There are three types of bascule bridge and the counterweights to the span may be located above or below the bridge deck. The fixed-trunnion (sometimes a "Chicago" bascule) rotates around a large axle that raises the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Strauss (engineer)
Joseph Baermann Strauss (January 9, 1870 – May 16, 1938) was an American structural engineer who revolutionized the design of bascule bridges. He was the chief engineer of the Golden Gate Bridge, a suspension bridge. Life, beginnings and death He was born in Cincinnati, Ohio, to an artistic family of German-Jewish ancestry. His mother was a pianist, and his father, Raphael Strauss, was a writer and painter. He graduated from the University of Cincinnati in 1892 with a degree in civil engineering. He served as both class poet and president, and was a brother of the Sigma Alpha Epsilon fraternity. Strauss had many hobbies. One of these included poetry. After completion of the Golden Gate Bridge he returned to his passion of poetry and wrote his most recognizable poem "The Mighty Task is Done". He also wrote "The Redwoods", and his "Sequoia" can still be purchased by tourists visiting the California redwoods. He died in Los Angeles, California, just one year after the Golden Gat ...

American Bridge Company
The American Bridge Company is a heavy/civil construction firm that specializes in building and renovating bridges and other large, complex structures. Founded in 1900, the company is headquartered in Coraopolis, Pennsylvania, a suburb of Pittsburgh. The firm has built many bridges in the U.S. and elsewhere; the Historic American Engineering Record notes at least 81. American Bridge has also built or helped build the Willis Tower, the Empire State Building, the Chrysler Building, launch pads, resorts, and more. During World War II, it produced tank landing ships (LSTs) for the United States Navy. In 2020, American Bridge Company was acquired by Southland Holdings LLC. History American Bridge Company was founded in April 1900, when J.P. Morgan & Co. led a consolidation of 28 of the largest U.S. steel fabricators and constructors. The company's roots extend to the late 1860s, when one of the consolidated firms, Keystone Bridge Company, built the Eads Bridge at St. Louis, the fi ...

Bridges Completed In 1919
A bridge is a structure built to Span (engineering), 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 ...

Historic American Engineering Record In Chicago
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...
