Rochester Covered Bridge
Rochester Covered Bridge is a covered bridge in Douglas County in the U.S. state of Oregon. Built by Floyd Frear in 1933, it carries Rochester Road over Calapooya Creek about west of Sutherlin. The bridge design, which ''Historic Highway Bridges of Oregon'' calls "unique among Oregon's housed structures", includes side windows with curved tops. The bridge has four windows on each side, portals with flat arched openings, and exposed false beams at the gable ends. According to the Oregon Department of Transportation, after county workers burned down another covered bridge in the vicinity in the late 1950s, a group of armed local residents guarded the Rochester Bridge one night to protect it from the same fate. The next day, county commissioners told the residents that the bridge would not be burned. In 1969, the county remodeled the bridge by replacing portal boarding, approaches, and abutments. ''Oregon's Covered Bridges'' includes a photograph of an earlier bridge here "at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calapooya Creek
Calapooya Creek is a tributary, about long, of the Umpqua River in Douglas County in the U.S. state of Oregon. Formed by its north and south forks, the creek drains a mountainous region south of the Calapooya Divide and east of Oakland and Sutherlin. The map includes mile markers along Calapooya Creek from mouth to source. From its source, the creek flows generally southwest through or near Nonpareil and Oakland. Near Oakland it passes under Oregon Route 99 and Interstate 5 and further downstream Oregon Route 138 before entering the river at the rural community of Umpqua. Bridge Rochester Covered Bridge carries Rochester Road over Calapooya Creek about west of Sutherlin. Built in 1933, its unusual design features side windows with curved tops. Tributaries Named tributaries from source to mouth are the North Fork Calapooya Creek and South Fork Calapooya Creek. Then come White, Coon, Timothy, Buzzard Roost, Cooper, and Filler creeks. Below these come Jeffers, Hinkle, Gil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Howe Truss
A Howe truss is a truss bridge consisting of chords, verticals, and diagonals whose vertical members are in tension and whose diagonal members are in compression. The Howe truss was invented by William Howe in 1840, and was widely used as a bridge in the mid to late 1800s. Development The earliest bridges in North America were made of wood, which was abundant and cheaper than stone or masonry. Early wooden bridges were usually of the Towne lattice truss or Burr truss design. Some later bridges were McCallum trusses (a modification of the Burr truss). About 1840, iron rods were added to wooden bridges. The Pratt truss used wooden vertical members in compression with diagonal iron braces. The Howe truss used iron vertical posts with wooden diagonal braces. Both trusses used counter-bracing, which was becoming essential now that heavy railroad trains were using bridges. In 1830, Stephen Harriman Long received a patent for an all-wood parallel chord truss bridge. Long's bridge con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Douglas County, Oregon
Douglas County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 111,201. The county seat is Roseburg. The county is named after Stephen A. Douglas, an American politician who supported Oregon statehood. Douglas County comprises the Roseburg, OR Micropolitan Statistical Area. History The area originally was inhabited by the Umpqua Indians, a grouping of natives who spoke a variety of Penutian and Athabaskan languages. Following the Rogue River Indian War in 1856, most of the remaining natives were moved by the government to the Grand Ronde Indian Reservation. However, seven families of Umpqua hid in the hills, eluding capture for many decades. They are now federally recognized as the Cow Creek Band of Umpqua Tribe of Indians. The tribe manages a small reservation in Canyonville, Oregon, and has a Casino/Hotel named Seven Feathers to represent the seven families who refused forced removal to the Grand Ronde Reservation.

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Gable
A gable is the generally triangular portion of a wall between the edges of intersecting roof pitches. The shape of the gable and how it is detailed depends on the structural system used, which reflects climate, material availability, and aesthetic concerns. The term gable wall or gable end more commonly refers to the entire wall, including the gable and the wall below it. Some types of roof do not have a gable (for example hip roofs do not). One common type of roof with gables, the gable roof, is named after its prominent gables. A parapet made of a series of curves (Dutch gable) or horizontal steps (crow-stepped gable) may hide the diagonal lines of the roof. Gable ends of more recent buildings are often treated in the same way as the Classic pediment form. But unlike Classical structures, which operate through trabeation, the gable ends of many buildings are actually bearing-wall structures. Gable style is also used in the design of fabric structures, with varying degree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Abutment
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end which provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan. The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.Pevsner, N. (1970) ''Cornwall''; 2nd ed. Harmondsworth: Penguin; p. 245 The impost or abacus of a column in classical architecture may also serve as an abutment to an arch. The word derives from the verb "abut", meaning to "touch by means of a mutual border". Use in engineering An abutment may be us ...

Bridges Completed In 1933
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.
