Aktor has undertaken the construction of the ‘Gold Line Underground’ in Doha, a line with a total length of 32km and 20 stations. The Gold line runs in an East-West direction and connects Airport City North via central Msheireb with Al Waab Street, Al Rayyan South and Salwa Road. It is the largest singular construction of the Doha Metro and it is due to be completed in August 2018. In addition, the role of Aktor in the massive metro construction has been crucial, not only of the ‘Athens Metro’, but also the metro of Thessaloniki, since Aktor was involved in the full range of relevant works, from tunnel boring to complete construction of the stations’ buildings.
