Salini Impregilo has completed the tunnel excavation work for Line 3 of the Riyadh Metro, the longest line of the massive project commissioned by the ArRiyadh Development Authority (ADA).

Line 3, or the Orange Line, is more than 40km long, with about 11km of that length underground, excavated by both TBM and the “cut and cover” method. Once completed, it will have 22 stations.

Salini Impregilo leads the ArRiyadh New Mobility (ANM) consortium, one of three involved in the $23bn six-line Riyadh Metro project that will cover 176 kilometres.

The metro system will reduce traffic congestion and air pollution in a city whose population is expected to rise from 6.5 million today to 8.3 million by 2030.

The end of the work was celebrated in the presence of Riyadh Governor HRH Prince Faisal bin Bandar Al Saud at the Qasr Al Hoqm Downtown Station.

Located near the Riyadh governor’s palace in the heart of the city, the Downtown Station will be one of the iconic stations, with two underground metro lines passing through it.

Covering 20,000m2, it was designed by the Norwegian architectural firm Snøhetta together with One Works and Crew. Its entrance will be covered by a massive inverted cone made of stainless steel that will provide shade for passengers and channel sunlight into the underground station.

Salini Impregilo is a globally recognised infrastructure leader, with projects under its belt including the Panama Canal expansion, the Grand Ethiopian Renaissance Dam, the Cityringen metro in Copenhagen, the Riyadh Metro and the Stavros Niarchos cultural centre in Athens.
