Crooked River High Bridge
The Crooked River High Bridge is a steel arch bridge that spans the Crooked River gorge in Jefferson County, Oregon. The bridge was designed by Conde McCullough and was completed in 1926. Shortly after its completion, Oregon State Highway Division created the Peter Skene Ogden Park just to the south of the bridge. The bridge has a total length of with a main span of . The deck is above the canyon floor. The bridge was eventually unable to keep up with the growing traffic demands of US 97 (US 97), and was replaced by the wider Rex T. Barber Veterans Memorial Bridge in 2000. The old bridge is open to pedestrians.

Jefferson County, Oregon
Jefferson County is one of the 36 counties in the U.S. state of Oregon. At the 2020 census, the population was 24,502. The county seat is Madras. The county is named after Mount Jefferson. History Jefferson County was created on December 12, 1914, from a portion of Crook County. The county owes much of its agricultural prosperity to the railroad, which links Madras with the Columbia River, and was completed in 1911, and to the development of irrigation projects in the late 1930s. The railroad was completed despite constant feuds and battles between two lines working on opposite sides of the Deschutes River. Madras was incorporated in 1911, and has been the permanent county seat since a general election in 1916. The first (temporary) county seat was Culver, which was selected by a three-man commission appointed by the governor. Due to repeated tie votes over several days (with one vote each cast for Culver, Metolius and Madras). The deadlock was eventually broken by allowing ...

Arch Bridge
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today. History Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks, the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction.

Crooked River (Oregon)
The Crooked River is a tributary, long, of the Deschutes River in the U.S. state of Oregon. The river begins at the confluence of the South Fork Crooked River and Beaver Creek. Of the two tributaries, the South Fork Crooked River is the larger and is sometimes considered part of the Crooked River proper. A variant name of the South Fork Crooked River is simply "Crooked River". The Deschutes River flows north into the Columbia River. Course The South Fork Crooked River originates in an area called Misery Flat, along the Deschutes County, Lake County and Harney County boundaries, north of Glass Buttes. The South Fork's tributaries drain Hampton Buttes to the west and Mackey Butte to the east. The South Fork Crooked River flows north for , collecting tributaries including Buck Creek and Twelvemile Creek before joining Beaver Creek to form the Crooked River proper near Paulina in Crook County. Beaver Creek arises in two forks, North Fork and South Fork Beaver Creek, in Grant Coun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peter Skene Ogden
Peter Skene Ogden (alternately Skeene, Skein, or Skeen; baptised 12 February 1790 – 27 September 1854) was a British-Canadian fur trader and an early explorer of what is now British Columbia and the Western United States. During his many expeditions, he explored parts of Oregon, Washington, Nevada, California, Utah, Idaho, and Wyoming. Despite early confrontations with the Hudson's Bay Company (HBC) while working for the North West Company, he later became a senior official in the operations of the HBC's Columbia Department, serving as manager of Fort Simpson and similar posts. Family Ogden was a son of Chief Justice Isaac Ogden of Quebec and his wife Sarah Hanson. The family was descended from a 17th-century British emigrant to the American colonies (Long Island and New Jersey). Both Isaac and his father David were Loyalists during the American Revolution; Isaac relocated to England at this time, then later returned to British-run Quebec. One of Peter's brothers, Charles Rich ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Bridges In The United States By Height
This is a list of the highest bridges in the United States by height over land or water. ''Height'' in this list refers to the distance from the bridge deck to the lowest point on the land, or the water surface, directly below. A bridge's deck height is greater than its ''clearance below'', which is measured from the bottom of the deck structure, with the difference being equal to the thickness of the deck structure at the point with the greatest clearance below. Official figures for a bridge's height are often provided only for the clearance below, so those figures may be used instead of actual deck height measurements. For bridges that span tidal water, the clearance below is measured at the average high water level. The minimum height for inclusion in this list is ', which may be either the ''deck height'' or the ''clearance below'' depending on available references. Note that the following types of bridges are not included in this list: demolished high bridges; historic high b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-spandrel Deck Arch Bridges In The United States
A spandrel is a roughly triangular space, usually found in pairs, between the top of an arch and a rectangular frame; between the tops of two adjacent arches or one of the four spaces between a circle within a square. They are frequently filled with decorative elements. Meaning There are four or five accepted and cognate meanings of the term ''spandrel'' in architectural and art history, mostly relating to the space between a curved figure and a rectangular boundary – such as the space between the curve of an arch and a rectilinear bounding moulding, or the wallspace bounded by adjacent arches in an arcade and the stringcourse or moulding above them, or the space between the central medallion of a carpet and its rectangular corners, or the space between the circular face of a clock and the corners of the square revealed by its hood. Also included is the space under a flight of stairs, if it is not occupied by another flight of stairs. In a building with more than one floor, ...

Bridges Completed In 1926
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] |
Road Bridges In Oregon
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", which i ...

Historic American Engineering Record In Oregon
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 ...
