The image below of the suspension bridge is not shown at full size. Its full size is 3036*888 so you can zoom in on it, and still see all the detail you need to see. It is quite a large design, but the detail you can see is when you zoom in is suffiecient to build it should you have sufficient pieces.
Following are three spreadsheets which you will find very useful. They help you determine what length pieces you will require to build certain shapes such as triangles, and which I believe was used to help build the bridge above
The files are &nbdp;
triangle2000.zip, A useful tool for building various shaped triangles
bridgev01arch.zip, A Bridge similar to the Sydney Harbour Bridge, in that it is a large single span bridge.
bridgev01rr.zip, I think this was the original version, from which the Arched Bridge was developed.
The image below is of a Crane I would love to build, or even to have enough pieces to actually build it, but I am working on that.
What I have actually managed to build myself, though in the picture it is still half built, I did finish it, though I have yet to find any photo's of it.
