Bridge
A bridge is a structure built to Span (engineering), span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path 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, 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 in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of ...

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 structural load, loads partially into a horizontal thrust restrained by the abutments at either side, and partially into a vertical load on the arch supports. 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 Greece, 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 Ancient Rome, Romans were – as with the Vault (architecture), vault and the dome – the first to fully realize the ...

West Montrose Covered Bridge (Oct
West Montrose Covered Bridge, also known as the "Kissing Bridge", is a covered bridge in West Montrose, Ontario, within Waterloo Region, one of the oldest covered bridges in Canada. The bridge is the only remaining historic covered bridge in Ontario and the second oldest surviving bridge in the Region of Waterloo. (In 2015, the total number of surviving covered bridges in Canada was below 200.) John Bear, who had previously built barns, built the bridge in 1880–1881, mostly of oak and white pine. The total cost to the Township of Woolwich was $3,197.50. The structure can still be used by pedestrians, buggy traffic and vehicles weighing less than three tonnes for crossing the Grand River. Since 1998, it has been owned and maintained by the Regional Municipality of Waterloo. The bridge's original design was described as a "two-span hybrid Howe truss" or as a "hybrid Queen Post – Howe timber configuration" with two louvred windows. (Additional windows, visible today, were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timber Bridge
A timber bridge or wooden bridge is a bridge that uses timber or wood as its principal structural material. One of the first forms of bridge, those of timber have been used since ancient times. History The most ancient form of timber bridge is the log bridge, created by felling a tree over a gap needing to be crossed. Among the oldest timber bridges is the Holzbrücke Rapperswil-Hurden crossing upper Lake Zürich in Switzerland; the prehistoric timber piles discovered to the west of the Seedamm date back to 1523 B.C. The first wooden footbridge led across Lake Zürich, followed by several reconstructions at least until the late 2nd century AD, when the Roman Empire built a wooden bridge. Between 1358 and 1360, Rudolf IV, Duke of Austria, built a 'new' wooden bridge across the lake that was used until 1878 – measuring approximately in length and wide. On April 6, 2001, the reconstructed wooden footbridge was opened, being the longest wooden bridge in Switzerland. The Kapell ...

Holzbrücke Rapperswil-Hurden
Holzbrücke Rapperswil-Hurden is a wooden pedestrian bridge between the city of Rapperswil and the village of Hurden crossing the Obersee (the upper part of Lake Zurich) in Switzerland. On 6 April 2001, the footbridge was opened. With a length of it is the longest wooden bridge in Switzerland. The wooden bridge has many predecessors. Wooden structures enabling lake crossings in the same area were already built thousands of years ago. Geography The pedestrian bridge is located next to the so-called Seedamm, a stone and metal structure which includes two bridges. Like the Seedamm it connects Rapperswil in the canton of St. Gallen and Hurden in the canton of Schwyz. The water area between Rapperswil and Hurden is the narrowest and shallowest part of Lake Zurich. While the Seedamm separates the Obersee part from the main part of Lake Zurich, the pedestrian bridge crosses the Obersee.

Log Bridge
A log bridge is a timber bridge that uses logs that fall naturally or are intentionally felled or placed across streams. The first man-made bridges with significant span were probably intentionally felled trees. The use of emplaced logs is now sometimes used in temporary bridges used for logging roads, where a forest tract is to be harvested and the road then abandoned. Such log bridges have a severely limited lifetime due to soil contact and subsequent rot and wood-eating insect infestation. Longer lasting log bridges may be constructed by using treated logs and/or by providing well drained footings National Parks Conference 1915, p. 59. "If we can design the abutment so that no moisture can collect under the logs the life of the bridge is materially increased." of stone or concrete combined with regular maintenance to prevent soil infiltration. This care in construction can be seen in the French bridge illustrated below, which has well locked dry set stone abutments and ...

Arkadiko Bridge
The Arkadiko Bridge or Kazarma Bridge is a Mycenaean bridge near the modern road from Tiryns to Epidauros in Argolis on the Peloponnese, Greece. The stone crossing, which is dated to the Greek Bronze Age, is one of the oldest crossable arch bridges still in existence. It is the oldest preserved bridge in Europe. The corbel arch bridge was constructed during the Mycenaean Period in a typical Cyclopean style contemporary to the Late Helladic period (III) (ca. 1300–1190 BC). The bridge, which is long, wide at the base and high, spans a culvert. The width of the roadway is about . Arkadiko Bridge was part of a military highway between the two cities of Tiryns to Epidauros which formed part of a wider Hellenic road network. The sophisticated layout of the bridge and the alignment of the road indicate that the bridge could be used by chariots. Three thousand years later, the bridge remains in local use. __NOTOC__ Other Mycenaean bridges in Argolis The Arkadiko Bridge is ...

Old English
Old English ( or , or ), or Anglo-Saxon, is the earliest recorded form of the English language, spoken in England and southern and eastern Scotland in the Early Middle Ages. It developed from the languages brought to Great Britain by Anglo-Saxon settlers in the mid-5th century, and the first Old English literature dates from the mid-7th century. After the Norman Conquest of 1066, English was replaced for several centuries by Anglo-Norman language, Anglo-Norman (a langues d'oïl, type of French) as the language of the upper classes. This is regarded as marking the end of the Old English era, since during the subsequent period the English language was heavily influenced by Anglo-Norman, developing into what is now known as Middle English in England and Early Scots in Scotland. Old English developed from a set of Anglo-Frisian or Ingvaeonic dialects originally spoken by Germanic tribes traditionally known as the Angles (tribe), Angles, Saxons and Jutes. As the Germanic settlers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mohammed VI Bridge
Muhammad (8 June 632 CE) was an Arab religious and political leader and the founder of Islam. According to Islam, he was a prophet who was divinely inspired to preach and confirm the monotheistic teachings of Adam, Noah, Abraham, Moses, Jesus, and other prophets.

Stepping Stones
Stepping stones or stepstones are sets of stones arranged to form an improvised causeway that allows a pedestrian to cross a natural watercourse such as a creek, a small river; or a water feature in a garden where water is allowed to flow between stone steps. Unlike bridges, stepstone crossings typically have no spans, although wood planks or stone slabs can be placed over between the stones (which serve as the piers) to improvise as low-water bridges. Although their historical origin is unknown, stepping stones, along with log bridges, are likely to have been among the earliest means of crossing inland bodies of water devised by humans. In traditional Japanese gardens, the term ''iso-watari'' refers to stepping stone pathways that lead across shallow parts of a pond, which work like a bridge-like slower crossing. Using ''iso-watari'' for crossing ponds, or shallow parts of streams, one can view the aquatic animals and plants around or in the pond, like carp, turtles, and w ...

Peloponnese
The Peloponnese ( ), Peloponnesus ( ; , ) or Morea (; ) is a peninsula and geographic region in Southern Greece, and the southernmost region of the Balkans. It is connected to the central part of the country by the Isthmus of Corinth land bridge which separates the Gulf of Corinth from the Saronic Gulf. From the late Middle Ages until the 19th century, the peninsula was known as the Morea, a name still in colloquial use in its demotic form. The peninsula is divided among three administrative regions: most belongs to the Peloponnese region, with smaller parts belonging to the West Greece and Attica regions. Geography The Peloponnese is a peninsula located at the southern tip of the mainland, in area, and constitutes the southernmost part of mainland Greece. It is connected to the mainland by the Isthmus of Corinth, where the Corinth Canal was constructed in 1893. However, it is also connected to the mainland by several bridges across the canal, including two submers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
