Chronic Logic

I need help http://www.pontifex2.com/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

I asked a friend of mine to build a bridge. He did and told me at what cost. Uhhh 70K lower than mine,, Whatta !#¤"  BUT when he told me how it was designed i wondered !,,,, Whould that work in RL ?? No way, but he still made a VERY cheap bridge...

Me personally want to see how you all designed youre bridge, not so much how much i cost.. Well thats me and im not angry/pissed that I know im not going to win this contest,but more interested in how it looks...

(Dont mind the english guys, long time since my last essay http://www.pontifex2.com/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

1. For this contest, only PERFECT BRIDGES will be accepted. That means that your bridge must have zero broken links on HARD difficulty and that the train cannot pass through any links on its voyage.

Hopefully it came out quoted http://www.pontifex2.com/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>
My question might be kind of stupid,but anyway. The ting im not completely sure about is the "and the train cannot pass through any links on its voyage." Could someone explain this to a Norwegian not so god in english wannabe bridgebuilder ?
