Mattar Al Tayer, Director General and Chairman of the Board of Executive Directors of Roads and Transport Authority (RTA) in Dubai, announced the completion of key tunnelling works of the Route 2020 Project stretching 3.2 km at a depth ranging from 12 to 36 meters.

Works in the metro viaducts are set for completion in November this year, and all railway works of the project will be accomplished in July 2019. The trial run of the metro will start in February 2020.

"The tunnel-drilling works commenced last October as the giant Tunnel Boring Machine, branded 'Al Wugeisha Expo 2020', started off Discovery Gardens and reached the underground station nearby Jumeirah Golf Estates, last February. The drilling works then continued past the Dubai Investment Park, and up to the final point at the Green Community," explained Al Tayer.

Al Wugeisha can crush stones and penetrate through sandy layers or any other soil components encountered during the drilling process.

It is also fitted with a machine for removing the soil, tubes for discharging the mud, and a control room in addition to other hi-tech components and features to accelerate the drilling process. The single concrete ring has six to seven moulds, each ring measures about 1.5 m in diameter.

Al Tayer was delighted with the progress of Route 2020 Project according to the schedule.
