Sheikh Mohammed bin Rashid al Maktoum recently launched the tunnel drilling works for the expansion of the Dubai Metro to reach Expo 2020. The drilling is expected to be completed by December 2018. There has also been funding agreed for the project in May this year.
The new section of the Metro starts from Nakheel Harbour and Tower and goes on for 15km to reach the Expo site. There will be some underground and some overground stations along the way. New trains have been ordered for the route and to upgrade current metro trains.
Dubai Media Office has released a video showing details of what is happening with regard to the Route 2020 expansion and you can see that here:
