Saudi Arabia’s government inaugurated the Riyadh Metro, ending a 12-year megaproject involving dozens of engineering, design, and contracting firms worldwide.
The driverless metro system, costing approximately US$ 23 billion, spans six lines over 176 km with 85 stations, including 34 elevated ones. It is designed to transport up to 3.6 million passengers daily, alleviating traffic congestion in a rapidly growing city overwhelmed by vehicles. The system's launch will occur in phases: Lines 1 (Blue), 4 (Yellow), and 6 (Purple) will open on December 1, 2024. Lines 2 (Red) and 5 (Green) are set for December 15, and Line 3 (Orange) will follow on January 5, 2025. In 2013, three international construction and engineering consortia were awarded contracts to design and build the lines and stations.
The King Abdullah Financial District (KAFD) station was designed by Zaha Hadid Architects (UK), the Qasr Al Hokm station by Snøhetta (Norway), the STC station by Gerber Architekten (Germany), and the Western Station by Omrania (KSA). The system's 183 trains were produced by Siemens (Germany) and Alstom (in collaboration with Bombardier, France) following a unified design by Avant Premiere (France).
