Two miles of moving roads, built into air-conditioned transparent tubes running from 15 to 22 feet above the ground, will link faye main entrances. One of the complaints at Montreal was that: the theme pavilone - which many visitors felt were the most interesting were located too far apart. At Osaka, the thene or symbol area will stretch for 900 yards across the centre of the site, and will be partly covered by the world's larga. transparent roof almost 900 feet long and 25 feet wide.
