Dubai's Expo 2020 vision is continuing to take shape - with preparations being stepped up in a bid to get the main construction work on the mammoth project complete a year early. About 40,000 workers will be on site from next year, with a focus on keeping to the tight schedule for Expo 2020 Dubai, a six-month-long world fair kicking off in two years' time - on October 20, 2020. In the Dubai South expo construction area, the winged steel-gold canopy of the distinctive main terminal station is being put in place and the graceful arches are clearly visible amid high mounds of sand and mud.
