bridges, 重庆_长江上的渡江大桥-1, image - Coggle Diagram

- - - - Arch bridge(stone),
        
        stable with the curve, and the gravity will be release during the gravity transport
      - Arch bridge (concrete), similar with stone made arch bridges but different
        
        Through arch bridge,
      - Beam bridge,
        
        made by wood but there is a beam or several beam.
      - Log bridge (beam bridge),
        
        similar with beam bridges but there is only one beam
      - Viaduct,
        
        Cavity wall viaduct,
        
        just like a pro arch bridge and most of it used by transportation
      - Bowstring arch,
        
        Box girder bridge,
        
        similar with viaduct but there is no hole under the bridge.
        
        Cable-stayed bridge, most of it is really long and tall.
        
        there is a bow like thing on the main bridge.
      - Cantilever bridge,
        
        similar with cable-staved bridge.
      - Cantilever spar cable-stayed bridge,
        
        Clapper bridge
        
        made by natural stone
      - th etruss bridge
        
        the truss bridge usually used in rail road and it can support most heavy things bridge.
  - - - Arch Is one type of bridge that does not have tension, It Is stabilized by one huge arch and a few pillars to further stabilize the bridge.
    - - The truss bridge Is a type of bridge without any support underneath It, It Is supported with many compression pillars on the bridge which connects to more compression supporters, the tensions add In the place to further connect the support and the bridge, kinda looks like triangles on top of the bridge.
    - - This Is the most common bridge type, both the tension and the compression are straight, one tension line and compression line is the road and two compression pillars are for stabilizing. It Is stronger within the number on pillars.
    - - A cantilever bridge Is split Into three parts, two parts are supported with triangular pillars and then supported with a compression pillar bellow, and Is also supported with the same on top. The middle part of the bridge Is supported with a small compression arch and small pillars.
    - - It Is like an upside down version of arch In tension, It has curved cables and It has two huge huge compression pillars to help stabilize the bridge. Examples: G
    - - The cable stay bridge Is a bridge supported by two super big pillars supporting from bottom to top, then, the huge pillar Is further connected to the bridge by many tension pillars.
- - - - Unique Bridge
        
        The Rolling Bridge Is a unique truss bridge thats Is 95 degrees, It can curled up and It started It's construction In 2004 and finished in 2005. It is 12 metres long and it resembles a steel and timber footbridge on top of the water. If there is boats passing through, there will be pistons pushing the bridge up to 90 degrees and it allows the boats to pass. The process of the construction costed 500,000 and won the British Structural Steel Design Award. Lastly it is located in Paddington Basin and I think it is very unique.
      - A bridge In Chonqing
        
        The Dongshuimen Bridge Is a cable stay bridge In Chongqing, it Is bright red within the supporting Ropes and the supporting barrier beneath. It is also a part of a truss bridge cause of the barrier and it is 1 kilometer long. It connects Yuzhong district to the Nan’an district which makes transporting a lot easier In Chongqing. The cost of It Is unknown, though it was started building during 2013 and was opened to civilians In 2014 made by China Railway Eighth Civil Engineering Group Corporation. It Is made by steel and concrete and Is very safe.
