Tunnel drilling for the Dubai Metro extension to the site of Expo 2020 is complete, The Roads and Transport Authority (RTA) has said.
Last October the giant tunnel boring machine, ‘Al Wugeisha Expo 2020’, started off in Discovery Gardens and reached the underground station nearby Jumeirah Golf Estates in February.
The tunnel then continued past Dubai Investment Park and up to the final point at the Green Community, said HE Mattar Al Tayer, Director General and Chairman of the Board of Executive Directors of the RTA.
Route 2020 tunnel stretches for 3.2 km at a depth ranging from 12 to 36 meters.
Al Tayer said he was delighted with the progress of Route 2020 Project according to the project schedule.
Work on the metro viaducts is set for completion in November this year, with all railway works due to be accomplished in July 2019 ahead of testing in February 2020.
