Parsons-led team will manage the $2.75 billion extension of Riyadh Metro's Red Line

The Royal Commission for Riyadh City selected the team in March, according to a Parsons release dated Nov. 3. Neither Parsons nor the commission has disclosed what the management contract is worth. Parsons, based in Chantilly, Virginia, described it as a multi-year assignment and new business for the firm.

The extension runs 8.4 km (about 5.2 miles) from King Saud University, today's end of the line, to Diriyah South: 7.1 km underground and 1.3 km elevated. It adds five stations, three underground and two elevated. Construction Review reported that two will serve the university area and three will sit in Diriyah, one of them planned as a future transfer to Line 7.

Construction goes to a consortium led by Italy's Webuild, which holds 30.1%. Its partners are Larsen & Toubro of India, NESMA of Saudi Arabia and Alstom of France. Webuild puts the design-build contract at $2.75 billion, covering the driverless line, signaling and tunnel boring machine excavation, Construction Review reported. The commission expects the work to take about six years.

RMTC has worked on the Riyadh Metro since 2013 and managed the first phase, which built the Blue, Red and Orange lines, Parsons said. The full network opened in late 2024 with six driverless lines covering about 176 km, according to Construction Review.
