The Tianjin Binhai Mass Transit (BMT) (滨海快速) or Jinbin light rail (津滨轻轨) is not like the other bridges on the list so far this one is a light rail fast transit line or a rapid metro train line. The longest all bridge part of this train line is 16.03 Miles long (25.7977 km). which makes this the 8th longest bridge in the world and first longest train bridge. This bridge connects Metropolitan Tianjin to TEDA which are both located in China.
The Donghai Bridge is the second longest cross-sea bridge and the 6th longest bridge in the world.
The bridge was the longest cross-sea bridge in the world for a few years until Hangzhou Bay Bridge was opened on May 1st, 2008.
Has droped in the list to the 16th place on the list of the longest bridges in the world at the time of writing this in nov. 2019 and is the third bridge on the list from china.
The Donghai Bridge (simplified Chinese: 东海大桥; traditional Chinese: 東海大橋; pinyin: Dōnghǎi Dàqiáo; literally "East Sea Grand Bridge") was completed on December 10th, 2005 and has a total length of 20.19 miles it connects Yangshan deep-water port and Shanghai in China.
The majority of the bridge is low-level viaduct but there are also cable-stayed sections to allow large ships passage.
Not sure how much steel was used in the construction of this bridge, but as always if I get these figures I will post them or if you have them feel free to comment so everyone can know.
Unrelated but could be of interest to you is the Donghai Bridge Wind Farm which is in the deep port producing 102 Mega Wats of offshore wind power that powers upto 200,000 homes, on july 6th 2010 it started pumping out power from these wind turbines and sent to the mainland grid to make it chinas first offshore wind farm.
The Runyang Bridge or Rùnyáng Chángjiāng Dàqiáo crosses the Yangtze River in Jiangsu Province, China. and is the 5th bridge in this series of worlds longest bridges
The bridge consist of two major bridges that link Tangzhou on the north of the river and Zhenjiang on the South. The bridge is part of the Beijing-Shanghai Expressway.
The south bridge is a suspension bridge with a span of 4888 ft it is the 3rd longest suspension bridge in the world, and the longest in China up untill 2007 when the Xihoumen Bridge was opened and made it the 2nd longest in china and 4th in the world.
Runyang Yangtze River Bridge
is now the fifth longest suspension bridge in the world and the 14 th longest overal bridge in the world comming in at a whooping 35.66 km or 22.16 miles of concrete and steel.
The main span of the bridge consists of a streamlined orthotropic steel box girder that is 3 metres (10 ft) in depth. The width of the deck is 39.2 metres (129 ft), accommodating 6 traffic lanes and a narrow walkway at each outside edge for maintenance. The height clearance for river navigation is about 50 metres (164 ft), and the highest point on the suspension bridge is 215 meters (4890 feet) .
The north bridge is a cable-stayed bridge with a span of 1332 ft with towers 492 ft abover water level. In the middle of the two bridges is the island of Sivezhou. The length of the bridge is 22.16 miles. The construction of the bridge started in October 2000 and was opened to the public on April 30th, 2005 , it was opened ahead of schedule
The Hangzhou Bay Bridge is the worlds 4th longest bridge 3rd longest over water bridge and the worlds longest Trans-oceanic bridge at 22.17 miles long .
Construction on this bridge started on June 8th, 2003 and was completed on June 14th, 2007. The opening ceremony was on June 26th, 2007 even though the bridge was not officially open to the public until May 1st, 2008. This is as of this posting the longest bridge in China and was built to last at least 100 years.
UPDATE: Hangzhou Bay Bridgeis no longer the 4th longest bridge in the world, as of today nov. 2019 it is now 13th it has droped 9 spots over the last 10-11 years due mostly to chinas rapid infrastructure growth over the same period. China holds 6 of the top 10 longest bridges in the world, Hangzhou Bay Bridge has many bridges under construction that will soon be added to our list of worlds longest bridges.
Hangzhou Bay Bridge is a bridge with cable-stayed bridge portions across the Hangzhou Bay off the east coast of china. The bridge was built in an s shape so that the annual silver dragon is minimally affected. The bridge has two main spans a 1,470 ft northern span and a 1,043 ft southern span.
The bridge has 6 express lanes in two directions. The speed limit is 62 miles per hour. Orthotropic steel deck is used on its main spans and five ramp bridges, and was paved with 50 millimeters (2.0 in) epoxy asphalt concrete.
The bridge uses different colors and flashing lights to keep drivers from getting drowsy and pay attention to the road instead. Previously the trip from Ningbo to Shanghai and southern Jiangsu involved a detour of around 400 km (249 mi), the bridge reduces that distance to 80 km (50 mi), a reduction of 320 km (199 mi).
The result is that Ningbo, with its port at Beilun, will be able to compete with Shanghai’s port Pudong for international sea freight.
This is just one of the investments China has made in it’s transportation infrastructure in the past few years.
The bridge is expected to boost tourism in Ningbo. Again I do not have the figures on how much steel was used in the construction of this bridge but if you get it I will post it, and as always if you have this information feel free to comment.
