Dinghai Bridge
Dinghai Bridge (in Chinese 定海大桥, and formerly 定马大桥) is an arch bridge over the Nandu River. The bridge connects Ding'an County on the south side of the Nandu, and Dongshan town in Xiuying District on the north. The bridge is located around 1 km west of Dingcheng and is the main access to that town from the north side of the Nandu. Dingcheng is located on the south side of the Nandu and is the main city in the county. Prior to 2017, there were two, makeshift wooden bridges connecting the north bank of the Nandu with the north of "Laocheng", the old part of Dingcheng. The new Dinghai Bridge replaces them and they are now closed. At the north end of the bridge, a road will eventually be built that will lead all the way north to Haikou. The bridge is 1,106 metres long and was expected to cost around 460,000,000 RMB The renminbi (; symbol: ¥; ISO code: CNY; abbreviation: RMB) is the official currency of the People's Republic of China and one of the world ...

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 ...

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. A list of Roman bridges compiled by the engineer Colin O'Connor featur ...

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 ...
