If you havenât played Cargo Bridge yet, go check it out: [url=http://armorgames.com/play/3999/cargo-bridge].
Itâs a really cool game .

Now if you have played the game, have tried the challenge mode and are stuck somewhere in the 20-35m area, this guide is exactly for you.
The problem the most people have is that in the main game you must build structural bridges, which arenât that long, but they must be quite stable. Using the same approach in the challenge mode might work until some 30m, but if you which to make longer bridges, you have to use a totally different approach.
So hereâs my attempt to build a 63m bridge; my design might not be perfect, but if worked quite good till now and it should give you just an idea how a 63m bridge could look like.

First of all, we need some supporters; as the range of the fixed nodes isnât that great, we are going to extend it artificially: [IMG]http://i300.photobucket.com/albums/nn33/C3H5O9N3/cb01.jpg[/IMG]



Now we have 2 additional nodes we can use to build our bridge.


Next step is to build a supporting steel construction, something like this:

Once youâre content with your construction (and it doesnât collapse yet ), just replace some connectors with the walks, so the guy can walk over the bridge:

Repeat the same process for the other side of the bridge:

Now you just have to connect the two ends with a light plank bridge. Make sure it doesnât have too strong bends and it isnât too tight. You can use the distance mark in the middle as a field marker (the lowest point of your bridge should be somewhere around that mark:

Now just cross your fingers and hope the bridge doesnât brake down. If it does, there are quite some tricks how to fix it. The most important thing is to watch where exactly does the bridge brake, so you know which part needs more supporters. Adding additional planks to places where you donât need them will only make your bridge heavier and more unstable.
The weakest links in my constructions are usually the connectors leading from the upper most node to the planks and that node itself. Hereâs how to fix the problem:

Adding 2 additional wood connectors over the steel connector will greatly increase its stability:

Adding an additional supporter node to support the upper most one is also an option:
