Metro Riyadh

Strukton, as a member of the FAST consortium, has been awarded a contract by Arriyadh Development Authority (ADA) to construct three of the six lines of a completely automatic and driverless metro system to be launched by the city. The total contract value amounts to € 6 billion. Strukton’s share represents almost € 1.0 billion.


This new metro will transform Riyadh, reducing traffic congestion, strengthening and driving the Saudi economy and improving living standards for citizens.

Impression Riyadh metro system

Riyadh currently has a population of 5.7 million, which is expected to increase to 8.3 million by 2030. The subway is a solution to daily traffic problems: of 7.4 million daily commutes, only 2% use public transport.

“Our experienced team is involved in numerous infrastructure projects, civil works and has an extensive knowledge in the field of rail systems. We are pleased that we were selected by the city of Riyadh to assist in this great project.”

Bert Hoekstra, director of Strukton International

Project details

The contract includes the design and construction of three lines: line 4 (yellow), line 5 (green) and line 6 (purple) (see metro map), which will have 25 stations. Construction will include 64.6 kilometres of rail consisting of:

  • 29.8 kilometres of viaducts
  • 26.6 kilometres of underground tracks
  • 8.2 kilometres of overground tracks

The largest metro project in the world

The six lines comprising the Riyadh metro project will span more than 176 kilometres, making it the largest subway under development in the world at present. Construction will require 600,000 tonnes of steel (80 times the amount used to build the Eiffel Tower), 4.3 million cubic metres of concrete (11 times the amount used for Burj Khalifa, the world's tallest skyscraper), and will employ over 30,000 people, of which more than half correspond to the consortium with Strukton.
