Bridges In China
This list of bridges in China includes notable bridges. China has a long history in bridge construction. The oldest bridge still in existence in China is the Anji Bridge, constructed during the years between 595 and 605. During the infrastructure boom of the past two decades, bridge-building has proceeded at a rapid pace on a vast scale. Prior to the completion of the Wuhan Yangtze River Bridge in 1957, there were no bridges across the Yangtze River, China's longest, from Yibin to Shanghai, and all overland roads and railways crossing this 2,884 km (1,792 mi.) stretch of the river had to be ferried. There were only seven such bridges in 1992, but that number reached 73 by the end of 2012, including eight new openings in that year alone. China has been pushing the boundaries of bridge construction with many record breaking bridges, including: * The Danyang–Kunshan Grand Bridge, the world's longest bridge measuring over . * The Yangsigang Yangtze River Bridge in Wu ...

Anji Bridge
The Anji Bridge () is the world's oldest open-spandrel segmental arch bridge of stone construction.This title strictly applies only to the ''sum of attributes given'' (O’Connor, Colin: ''Roman Bridges'', Cambridge University Press 1993, , p.171): Various Roman stone pillar bridges featured wooden open-spandrel segmental arches as early as the 2nd century CE, among them Trajan's bridge, the longest bridge of the world to have been built for over a thousand years. Also, a dozen or more Roman close-spandrel stone segmental arch bridges are known from the 1st century BC onwards, such as the Ponte San Lorenzo (Padua), Alconétar Bridge and the Makestos Bridge (Turkey), the last having half-open spandrels. The 27 segmental arches of the Bridge at Limyra (300 ce) feature span to rise ratios between 5.3 and 6.5 to 1, making it an earlier example of a stone quarter circle segmental arch bridge. This leaves the Anji bridge the title of "the oldest ''open-spandrel'' stone quarter circle seg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Longest Arch Bridge Spans
This list of the longest arch bridge spans ranks the world's arch bridges by the length of their main span. The length of the main span is the most common way to rank bridges as it usually correlates with the engineering complexity involved in designing and constructing the bridge. If one bridge has a longer span than another it does not necessarily mean that the bridge is longer from shore to shore or from abutment to abutment. Completed bridges Under construction History of largest spans Flags refer to present national boundaries.

World Heritage Logo Global
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as #Monism and pluralism, one simple object while others analyze the world as a complex made up of many parts. In ''#Scientific cosmology, scientific cosmology'' the world or universe is commonly defined as "[t]he totality of all space and time; all that is, has been, and will be". ''#Theories of modality, Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''#Phenomenology, Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''#Philosophy of mind, philosop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luoyang Bridge
The Luoyang Bridge, also known as Wan'an Bridge, is located in Quanzhou, Fujian province, China. The stone bay bridge is situated at the mouth of Luoyang River. Being the first stone bay bridge in China, it enjoys the reputation of "one of the four ancient bridges of China". The project started from the fifth year (1053) of Huangyou's ruling period in the Northern Song dynasty. Cai Xiang, the chief of Quanzhou prefercture in the 3rd year (1058) of Jiayou's reign, took over the task of constructing the bridge, who had overcome several difficulties concerning bridge deck pavement and bridge pier by applying a raft foundation and raising oysters in the river to solid the base. In the fourth year (1059) of Jiayou's reign, the construction of Luoyang bridge was completed and Cai Xiang wrote "The Wan'an bridge" for it. The bridge had been reconstructed and repaired in the later dynasties. In the Southern Song dynasty, pagodas and fengshui pagodas were built outside the guardrail of the ...

Luoyang Bridge2
Luoyang is a city located in the confluence area of Luo River and Yellow River in the west of Henan province. Governed as a prefecture-level city, it borders the provincial capital of Zhengzhou to the east, Pingdingshan to the southeast, Nanyang to the south, Sanmenxia to the west, Jiyuan to the north, and Jiaozuo to the northeast. As of December 31, 2018, Luoyang had a population of 6,888,500 inhabitants with 2,751,400 people living in the built-up (or metro) area made of the city's five out of six urban districts (except the Jili District not continuously urbanized) and Yanshi District, now being conurbated. Situated on the central plain of China, Luoyang is among the oldest cities in China and one of the cradles of Chinese civilization. It is the earliest of the Four Great Ancient Capitals of China. Names The name "Luoyang" originates from the city's location on the north or sunny ( "yang") side of the Luo River. Since the river flows from west to east and the sun is to ...

Bridge At Limyra
The Bridge near Limyra (in tr, Kırkgöz Kemeri, "Bridge of the Forty Arches") is a late Roman bridge in Lycia, in modern south-west Turkey, and one of the oldest segmented arch bridges in the world. Located near the ancient city of Limyra, it is the largest civil engineering structure of antiquity in the region, spanning the Alakır Çayı river over a length of on 26 segmental arches. These arches, with a span-to-rise ratio of 5.3:1, give the bridge an unusually flat profile, and were unsurpassed as an architectural achievement until the late Middle Ages. Today, the structure is largely buried by river sediments and surrounded by greenhouses. Despite its unique features, the bridge remains relatively unknown, and only in the 1970s did researchers from the Istanbul branch of the German Archaeological Institute carry out field examinations on the site. Field examinations No information on the bridge survives from ancient sources. The first descriptions appear in European ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Makestos Bridge
The Macestus Bridge or Bridge of Sultançayır was a Roman bridge across the Macestus River ( tr, Simav or ''Susurluk Çayı'') at Balıkesir, in the northwestern part of modern-day Turkey. Its flattened arches, slender piers and the hollow chamber system documented the progress made in late antique bridge building. A first cursory investigation of the 234 m long structure was conducted in the early 20th century, but since then its existence has been largely neglected by scholars. Current photos from 2009 show that the bridge has collapsed in the meantime. Exploration The bridge is located at Sultançayır, in the heart of the ancient region of Mysia, where it carried the road connecting Hadrianu Therai (''Balıkesir'') with Miletopolis across the Macestus. During an exploration tour in 1902, the German archaeologist Theodor Wiegand found the ancient structure still in an excellent state of preservation; only the fourth pier from the eastern bank had been blown up some th ...

Alconétar Bridge
The Alconétar Bridge (Spanish: ''Puente de Alconétar''), also known as Puente de Mantible, was a Roman segmental arch bridge in the Extremadura region, Spain. The ancient structure, which featured flattened arches with a span-to-rise ratio of 4–5:1, is one of the earliest of its kind. Due to its design, it is assumed that the bridge was erected in the early 2nd century AD by the emperors Trajan or Hadrian, possibly under the guidance of Apollodorus of Damascus, the most famous architect of the time. The almost 300 m long Alconétar Bridge served as a crossing point for the Roman '' Via de la Plata'', the most important north-south connection in western Hispania, over the Tagus, the longest river of the Iberian peninsula. It presumably remained in service until the Reconquista, after which numerous early modern reconstruction attempts by Spanish engineers failed. The ruins, which were mainly to be found on the right river bank, were relocated from their original position in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ponte San Lorenzo
The Ponte San Lorenzo is a Roman bridge over the river Bacchiglione in Padua, Italy. Constructed between 47 and 30 BC, it is one of the very earliest segmental arched bridges in the world. It is also notable for the slenderness of its piers, unsurpassed in antiquity. Location The Ponte San Lorenzo was one of four Roman bridges in ancient Padua crossing the Medoacus (modern Bacchiglione). Located in the ''Via San Francesco'', the three-arched bridge is today for the most part framed by surrounding buildings, which have moved closer to the river over the centuries. Only its eastern arch spanning the restricted waterway was largely visible until the middle of the 20th century, when it too disappeared from view as the remaining canal was filled up to the ''Riviera del Ponti Romani'' street. The intact arches of the bridge still exist below street level and can be visited at fixed times by the public. Earthworks in 1773 and 1938, during which parts of the bridge were temporaril ...
