The consortium led by the US company Parsons, alongside Systra and Egis, will manage and supervise the works for the extension of the red line of the Riyadh Metro.
The project, valued at approximately EUR 2.45 billion, involves the construction of 8.4 km of infrastructure and five new stations.
The American company Parsons has announced that the Riyadh Metro Transit Consultants (RMTC) consortium, which it leads alongside the French groups Systra and Egis, has been selected to manage and supervise the extension of the Riyadh Metro’s Red Line, in the capital of Saudi Arabia.
The decision was taken in March 2026 by the Royal Commission for Riyadh City (RCRC), the authority responsible for the development of the Saudi capital, but Parsons officially announced the contract on Monday, 2 November.
The contract is multi-year and covers project and construction management services. Its value has not been disclosed.
An 8.4 km extension with five stations
The project involves extending the red line (Line 2) from its current terminus at King Saud University to Diriyah South, to connect the historic and tourist area of Diriyah to the capital’s public transport network.
The new section will be 8.4 km long, of which 7.1 km will be underground and 1.3 km on viaducts.
Five new stations will be built: three underground and two above ground. Two will serve King Saud University, including the medical area and the main campus, whilst the other three will be located in Diriyah.
One of the stations in Diriyah will, in future, allow passengers to transfer to Line 7, which is currently under development.
A tunnel boring machine (TBM) with a cutting head 11.16 metres in diameter will be used to construct the tunnels.
The Saudi authorities have estimated that the extension will take approximately six years to complete, with completion expected around 2032.
Construction contract worth EUR 2.45 billion
The contract for the design and construction of the extension was awarded in January 2026 to a consortium led by the Italian company Webuild, which also includes the Indian group Larsen & Toubro, the Saudi company Nesma and the French manufacturer Alstom.
The contract is worth USD 2.75 billion, equivalent to approximately EUR 2.45 billion.
Work began in March 2026 with the construction of the two stations in the King Saud University area.
The consortium led by Parsons will oversee the progress of these works and the integration of the new section into the existing network, including ensuring compliance with technical requirements and the construction schedule. More
