Nandu River
The Nandu River () is the longest river in Hainan Province, China. Its tributary is the Xinwu River. The river discharges into the Nandu River estuary at Haikou city, and then into Qiongzhou Strait. The river is 314 km long, with a discharge of 6.099 billion cubic metres. It passes the major settlements of Chengmai Zhen in Chengmai County then Dingcheng in Ding'an County. The river then turns north, goes over the Longtang Dam at Longtang, a somewhat smaller town than Chengmai and Ding'an. The Nandu then goes under several bridges, such as the Nandu River Iron Bridge and Qiongzhou Bridge. Once passed the Qiongzhou Bridge, at the southern tip of Xinbu Island, the Nandu flows north along the east side of Xinbu Island and out into the sea. At the southern tip of Xinbu Island, two distributaries branch off. One is the Henggouhe Channel which runs along the west side of Xinbu Island. The other is the smaller Haidian River which flows westward, under the Haikou Century Bridge, and ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haikou
Haikou (; ), also spelled as Hoikow is the capital and most populous city of the Chinese province of Hainan. Haikou city is situated on the northern coast of Hainan, by the mouth of the Nandu River. The northern part of the city is on the Haidian Island, which is separated from the main part of Haikou by the Haidian River, a branch of the Nandu.

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai.

Tied-arch Bridge
A tied-arch bridge is an arch bridge in which the outward horizontal forces of the arch(es) caused by tension at the arch ends to a foundation are countered by equal tension of its own gravity plus any element of the total deck structure such great arch(es) support. The arch(es) have strengthened chord(s) that run to a strong part of the deck structure or to independent tie-rods below the arch ends. Description Thrusts downwards on a tied-arch bridge deck are translated, as tension, by vertical ties between the deck and the arch, tending to flatten it and thereby to push its tips outward into the abutments, like for other arch bridges. However, in a tied-arch or bowstring bridge, these movements are restrained not by the abutments but by the strengthened chord, which ties these tips together, taking the thrusts as tension, rather like the string of a bow that is being flattened. Therefore, the design is also called a bowstring-arch or bowstring-girder bridge. The elimination o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guoxing Avenue
Guoxing Avenue () is a major street in Haikou, Hainan, China. It runs in an east-west direction in the heart of the city. Its west end terminates at Longkun Road and its east end terminates at the Qiongzhou Bridge which crosses the Nandu River. History Guoxing Avenue was once Haikou's main airport (since relocated to Haikou Meilan International Airport southeast of the city centre). Built around 2005, the avenue was first seldom used for vehicular traffic route. Most of the land on the north and south sides were unoccupied. It has since become a heavily trafficked road. In 2017, the west end was connected to a newly built road that provides access to the new neighbourhood 'Haikou West Coast' located around 7 km west of the Haikou city centre. The east end of Guoxing connects to the route to Haikou Meilan International Airport. Notable locations Guoxing can be considered as having two parts separated by the north-south Haifu Road: West The west part contains the following: ...

Nandu River Iron Bridge
The Nandu River Iron Bridge (), also known as the Devil's Iron Bridge, Old Iron Bridge, and originally the Lu Palace Bridge (), is a partially collapsed, steel truss bridge over the Nandu River, in the north of Hainan Province, China. Opened to traffic in 1942, it was Hainan's first bridge over the Nandu River. History The bridge was built by the Imperial Japanese Army during the Second Sino-Japanese War to provide access to the land west of the river. On March 26, 1940, approval was given to begin design and construction. The responsibility for the bridge's construction was given to the Japanese company Shimizu Group Contracting, with the steel frames built by Taiwan's Kaohsiung Shipbuilding Production and Installation. The bridge is long, wide, and has a concrete deck. A cylindrical, concrete guard house remains at the eastern end with horizontal openings. The bridge was designed for a maximum useful lifespan of 20 years, and could carry 20 tons. After Japan's defeat in Worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Road Bridges In China
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 ...

Bridges In Hainan
A bridge is a structure built to Span (engineering), 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 ...
