On 08.07.2015 the TBM Jazlah (diameter 10 m, weight 700 t) started driving the 5.8 km-long tunnel of the 41.2 km Orange Line of the Riyadh Metro. The contractor, ArRiyadh New Mobility Consortium (ANM), is led by Italian Salini Impregilo. The tunnel is located in downtown Riyadh and will pass through the main railway station. The alignment of the Orange line, which will be the longest in Riyadh, is mostly elevated along the western part of Al-Madinah Al-Munawwarah Road, then underground in bored and mined tunnels in the central section of the line, and generally at grade along Prince Saad Ibn Abdulrahman Road in the east. The line will be equipped with 22 stations. Click sa/13 for tunnelbuilder archive. Visit http://www.arriyadh.com/Eng and http://riyadhmetro.com/. 28/15.
