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 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 length of the eastern part of the bridge, from Zhongshanmen to Donghailu, is 28.22 miles, of which, 24.8 miles is elevated, and 3.41 miles is on ground, taking a total of around an hour in either direction. A big portion of the service is alongside with the Jintang expressway. The west part, from Zhongxinguangchang to Zhongshanmen, will be 4.57 miles long, of which, 0.36 miles will be elevated, 0.17 miles will be transition, 4.14 miles will be below ground. The total length of the line will be 32.78 miles, and the Binhai line is the longest rapid transit line in China. The construction work of the west part began in 2004, to be completed in 2008.
The train used for the Binhai Mass Transit can travel up to 62.14 miles per hour, which is the record speed for any rapid transit system in China. Construction of the bridge/rapid transit line began on May 18th, 2001 and was finished on September 30th, 2003. The lines where opened in 2004.

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.
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.

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.
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).
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 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.
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.
