CARGO BRIDGE 2

Today I played anew game.
My teacher Mr.Lafleur taught me the Lafleur technique.
He is the best engineering teacher in Okadai!!! :)
Now I can build bridges.


this is a picture from level 8.

I used the following:

-2 pieces of metal
-6 walks
-5 ropes

I tested my bridge with the elephant and bob stopped in the middle :

My bridge held infinity.
Can you do better ? I challenge you.
