Byrne's Ferry Covered Bridge
The Byrne's Ferry bridge was a historic cantilevered covered bridge across the Stanislaus River between Calaveras County and Tuolumne County, California. Originally built during the California Gold Rush, the bridge was located on the O'Byrne's Ferry road between Chinese Camp and Copperopolis. Until the mid-20th century, it was one of the last remaining covered bridges in the state; the bridge was destroyed in 1957 (after an unsuccessful attempt to move it) to make way for the construction of Tulloch Dam. History The bridge was named after the P. O. Byrne ferry which operated on the Stanislaus River as early as 1849 to service gold seekers in the area. At that time, the crossing locale was known as Waterville and, later, Poker Flat. Bret Harte's ''The Outcasts of Poker Flat'' is said to be written of this site. Patrick (or Peter; it is not known which, as he signed all stock certificates as P. O. Byrne) O. Byrne established a river crossing ferry here and determined that there wa ...

Covered Bridge
A covered bridge is a timber-truss bridge with a roof, decking, and siding, which in most covered bridges create an almost complete enclosure. The purpose of the covering is to protect the wooden structural members from the weather. Uncovered wooden bridges typically have a lifespan of only 20 years because of the effects of rain and sun, but a covered bridge could last over 100 years. In the United States, only about 1 in 10 survived the 20th century. The relatively small number of surviving bridges is due to deliberate replacement, neglect, and the high cost of restoration. European and North American truss bridges Typically, covered bridges are structures with longitudinal timber-trusses which form the bridge's backbone. Some were built as railway bridges, using very heavy timbers and doubled up lattice work. In Canada and the U.S., numerous timber covered bridges were built in the late 1700s to the late 1800s, reminiscent of earlier designs in Germany and Switzerland. Th ...

Buildings And Structures In Calaveras County, 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] |
Road Bridges In California
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", whic ...

Cantilever Bridges In The United States
A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In the southe ...

Wooden Bridges In California
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the production ...

Demolished Bridges In The United States
Demolition (also known as razing, cartage, and wrecking) is the science and engineering in safely and efficiently tearing down of buildings and other artificial structures. Demolition contrasts with deconstruction, which involves taking a building apart while carefully preserving valuable elements for reuse purposes. For small buildings, such as houses, that are only two or three stories high, demolition is a rather simple process. The building is pulled down either manually or mechanically using large hydraulic equipment: elevated work platforms, cranes, excavators or bulldozers. Larger buildings may require the use of a wrecking ball, a heavy weight on a cable that is swung by a crane into the side of the buildings. Wrecking balls are especially effective against masonry, but are less easily controlled and often less efficient than other methods. Newer methods may use rotational hydraulic shears and silenced rock-breakers attached to excavators to cut or break through wo ...

California Department Of Parks And Recreation
The California Department of Parks and Recreation, more commonly known as California State Parks, manages the California state parks system. The system administers 279 separate park units on 1.4 million acres (570,000 hectares), with over 280 miles (450 km) of coastline; 625 miles (1,000 km) of lake and river frontage; nearly 15,000 campsites; and 3,000 miles (4,800 km) of hiking, biking, and equestrian trails. Headquartered in Sacramento, park administration is divided into 21 districts. The California State Parks system is the largest state park system in the United States. History California's first state park was the Yosemite Grant, which today constitutes part of Yosemite National Park. In 1864, the federal government set aside Yosemite Valley for preservation and ceded the land to the state, which managed the famous glacial valley until 1906. California's oldest state park, Big Basin Redwoods State Park, was founded in 1902. Until 1921, each park was mana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Native Sons Of The Golden West
The Native Sons of the Golden West is a fraternal service organization founded in the U.S. state of California in 1875, dedicated to historic preservation, documentation of historic structures and places in the state, the placement of historic plaques and other charitable functions within California. In 1890 they placed the first historical marker in the state to honor the discovery of gold, which gave rise to the state nickname "Golden State" and "Golden West." Former U.S. President Richard M. Nixon and former Chief Justice Earl Warren were both past presidents of the NSGW. History The Native Sons of the Golden West was founded 11 July 1875 by General A. M. Winn, a Virginian, as a lasting monument to the men and women of the Gold Rush era. General Winn had lived in California during the Gold Rush and was impressed with the spirit and perseverance of the Forty-Niners. Speaking of his object in organizing the Order General Winn said, "For twenty years my mind had been running ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
