The road that leads nowhere...

Whilst Tom and I were exploring the joys of 'Tokyo Big Sight' we were on the roof of the 4th floor and we saw lots of lovely things...

First, there was a area marked for 'jidouhanbaiki's' (vending machines), with NO vending machines

Where did the vending machines go?!

Then, as we looked over the edge of the building, we saw this genius design for a road...

It seems to siphon traffic off the main road and lead them to a round-about, which only allows you to exit the same way you came in.

Great isn't it?
