I cry foul on the World Record numbers. On the first urban bridge it is reported that several people finished the bridge with only SEVEN pieces. That won't even build decking, let alone any support structure. Either the record recording feature is bugged or has been hacked.
However, if I'm wrong, someone please post how to build a successful bridge with seven pieces.
