11th June 2015. The Doha Metro marked a major milestone at 9.08am on Thursday when Al Mayeda TBM made a historic “breakthrough” at the main interchange station at Msheireb.
TBM “Princess Wencheng” has the mission to construct the 1.6km long tunnel for the Kowloon City Section of the project.
India’s longest road tunnel is likely to overshoot the May 2016 deadline to become driver-ready.
Excavation work has stopped some three months ago because of the dispute between project concessionaire IL&FS Transportation Network and the construction contractor, Leighton India Contractors.
Geodata SpA was in charge of the design.
