If you haven’t played Cargo Bridge yet, go check it out: [url=http://armorgames.com/play/3999/cargo-bridge].
It’s 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 aren’t 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 here’s 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 isn’t 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 you’re content with your construction (and it doesn’t 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 doesn’t have too strong bends and it isn’t 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:
[IMG]http://i300.photobucket.com/albums/nn33/C3H5O9N3/cb05.jpg[/IMG]

Now just cross your fingers and hope the bridge doesn’t 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 don’t 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. Here’s 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:

I hope this helps. If you have any questions about my design, tips for better bridges or you just want to share your super cool bridges, feel free to post theme here.

Now why does armorgames has it's own image codes and why aren't we able to edit our posts :D.

Anyway here are just the images again:

I'm on lvl 22 in that game and I've tried walkthroughs, videos I even tried to hack it!

But that game possibly has the worst physics engine I've ever seen. It is near to impossible to replicate any bridges.

Actually, it has a beautiful physics engine. It's so good, it you're off by half a meter, your bridge fails.

Nice tips, to bad I can't get past level 15 : (.

I like your tips, but i don't think that I will ever use them cause I can't win almost no level.

Even the author of this game admits the flaws of it.

@nozo_ito thanks, but those kinds of bridges are impossible for me, it breaks at the start of the game and I kinda stopped [laying that game... like.. forever it can get frustrating to watch your bridges fall on it's own weight. :\\
