MIN Size for Bridge B and Bridge C please

[coinutah]

What is the min. length and width for bridge C and B??? Also in the center what is the block size we must leave room for to attach?
I see many posts but having this all in one post would be nice. Also the 20cm for the block seems large for a little block to attach to the bucket,

I would really recommend looking at a rule book if you have not done so already. It clearly explains every building specification that you need to know for this event.
