With the breakthrough of TBM S-867 on 10.10.2015 and S-865 on 13.10.2015 at the Legtaifiya Station in Doha, Salini Impregilo, leader of the ISG joint venture, has completed 11 out of the 16 tunnelling drives across the Red Line North Project completing 70% of tunneling works in Doha.

Legtaifiya Station will be the interchange point between the Metro System and the Lusail Railway Transport System. TBMs S-865 and S-867 will start their final drives towards the Golf Course where they are expected to finish early in 2016.

The ISG joint venture is currently deploying another 2 TBMs which are excavating in the West Bay area passing just below Doha’s unique skyline.

The red line underground extends in a northerly direction from the station of Mushaireb, for approximately 13 km, through seven newly built underground stations.

The project involves the excavation of two parallel tunnels, one in each direction, approximately 11.6 km long with an internal diameter of 6.17 m.

The red line north underground, together with a further 3 metro lines, forms part of the project to build the new infrastructure system for the city in Qatar which is part of the National Development Plan for 2030.
