See 36 of them (world's longest, one a multi-turn helix*, many very beautiful, some over shallow international ocean waters, one 36Km wide between land points, etc. some with very unusually support structures) at: http://www.slideboom.com/presentations/184256/China'sAmazingBridges-2003v Be warned it is a mass of data so may down load slowly, but start it and do something else - they are well worth seeing. At least open site, page down, and read immediately the paragraph of text about several of the bridges. *This is a bridge that changes the road level in short space. Norway has some helix tunnels inside mountains to do this vertical change too.
