The Royal Commission for Riyadh City (RCRC) in Saudi Arabia has awarded a US$2.75 billion contract to a consortium led by Webuild, which holds a 30.1% share, equal to approximately US$830 million together with India’s Larsen & Toubro (L&T), Saudi Arabia’s NESMA, and France’s Alstom — to design and build an 8.4 km extension of the Riyadh Metro’s Red Line, including five driverless stations and associated infrastructure. 

The project includes the design and construction of an 8.4 km new driverless metro line, 1.3 km of which will be on viaduct and the remaining 7.1 km in tunnels. It also includes five stations, three of which will be underground, as well as all signaling systems. A Tunnel Boring Machine (TBM) will be used for the excavation of the underground section.
