Fruitvale Bridge
The Fruitvale Bridge and the Fruitvale Avenue Bridge (the latter officially the Miller-Sweeney Bridge at Fruitvale Avenue) are parallel bridges that cross the Oakland Estuary, linking the cities of Oakland, California, Oakland and Alameda, California, Alameda in California. The Fruitvale Bridge is a vertical-lift Warren through truss railroad moveable bridge, while the Fruitvale Avenue Bridge is a steel stringer road bascule bridge that connects Fruitvale Avenue in Oakland with Tilden Way in Alameda. Rail bridge The rail bridge is immediately northwest of the Miller-Sweeney road bridge. The rail bridge connected Fruitvale Avenue in Oakland with Tilden Way in Alameda. It has been out of service since 2000. History This lift bridge was constructed in 1951 to replace an earlier bridge that originally served the East Bay Electric Lines, SP interurban trains from San Francisco (SP's Interurban Electric Railway discontinued service in 1941). From 1951 until September 11, 1996, the Sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oakland Estuary
The Oakland Estuary is the strait in the San Francisco Bay Area, California, separating the cities of Oakland and Alameda and the Alameda Island from the East Bay mainland. On its western end, it connects to San Francisco Bay proper, while its eastern end connects to San Leandro Bay. Crossings The Estuary is spanned by two underwater tubes and three bridges. They are, from west to east: * Webster Street Tube * Posey Tube *Park Street Bridge *Fruitvale Bridge *High Street Bridge Early history Although the estuary was used by Native American tribes inhabiting the local area since about 4000 BC, the earliest recorded history of the Oakland Estuary dates primarily from events extending back to the 19th century, as detailed in a research study conducted by Earth Metrics for the U.S. Army Corps of Engineers (Earth Metrics, 1990)(Shreffler, 1994). The Oakland Estuary and tributary stream channels were used for shipping transport regularly by the 1850s; early maritime commerce f ...

High Street Bridge
The High Street Bridge is a double-leaf bascule drawbridge spanning 296 feet of the Oakland Estuary in the San Francisco Bay Area, California, United States. It links the cities of Oakland and Alameda. The bridge is opened approximately 1,400 times a year. The bridge carries an average of 26,000 vehicles per year. The bridge was built when the Oakland Estuary was trenched, converting Alameda from a peninsula to an island. The High Street Bridge is one of the four bridges and two tunnels that allow access to Alameda. History The estuary was originally spanned by an iron swing bridge, completed in 1894 by the Harrison Bridge Company for $24,747. In May 1901, a fire destroyed the swing span and part of the approaches, which were rebuilt the following year. Three bridges were built by the federal government in 1901 at High Street (road), Park Street (road), and Fruitvale Avenue (combined road and rail) in exchange for permission and rights-of-way to dredge the channel between ...

Bridges Completed In 1951
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.

Steel Bridges In The United States
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Oakland, California
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railroad Bridges In California
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 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 sleepers (ties) set in 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 frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilit ...

1989 Loma Prieta Earthquake
The 1989 Loma Prieta earthquake occurred on California's Central Coast on October 17 at local time. The shock was centered in The Forest of Nisene Marks State Park in Santa Cruz County, approximately northeast of Santa Cruz on a section of the San Andreas Fault System and was named for the nearby Loma Prieta Peak in the Santa Cruz Mountains. With an magnitude of 6.9 and a maximum Modified Mercalli intensity of IX (''Violent''), the shock was responsible for 63 deaths and 3,757 injuries. The Loma Prieta segment of the San Andreas Fault System had been relatively inactive since the 1906 San Francisco earthquake (to the degree that it was designated a seismic gap) until two moderate foreshocks occurred in June 1988 and again in August 1989. Damage was heavy in Santa Cruz County and less so to the south in Monterey County, California, Monterey County, but effects extended well to the north into the San Francisco Bay Area, both on the San Francisco Peninsula and across the bay ...
