The Riyadh Metro (Arabic: مترو الرياض) is a rapid transit system serving the city of Riyadh. It consists of 6 metro lines spanning a total length of 176 kilometers with 85 stations. The project cost $22.5 billion to build. It is scheduled to open in 2019.
Estimates suggest that the number of Riyadh's population will grow from about 6 million to more than 8.5 million over the next 10 years. This will require the provision of more effective alternative ways to meet the needs of the city from population growth and transportation.
The groundbreaking ceremony was celebrated on April 4, 2014, with an opening now projected for 2018.
It is currently being built by construction companies including Bechtel, FCC, Strukton, Salini Impregilo, Larsen and Toubro and Samsung. It is expected to be the backbone of the city's public transport system. Integrated with an 85-kilometre (53 mi) three-line bus rapid transit (BRT) network.
The project will contribute to reducing the number of car trips by nearly 250 thousand trips a day, equivalent to 400 thousand liters of fuel per day, thus reducing the air pollutant emissions in the city. It is expected that the capacity of the project will reach 3.6 million passengers a day. After a few years from starting the project it will reach 1.16 million passengers in the beginning of the operation.
In January 2017, Riyadh Governor Prince Faisal bin Bandar stated that 48% of the project had been completed.

Operating control center
The project includes the construction of an advanced center for the control and operation of the train traffic management and control, and monitor all elements of the system of stations and tracks and facilities and systems, and will provide the center with the latest operating control and monitoring systems.
Monorail project will also include technical specifications and high design, notably the use of automated rail system (without driver), choose the latest specifications and technologies to vehicles electric train in the world, which allows the separation of the vehicles from the inside, and the allocation of a special category for families, in addition to providing them with communication services and the exchange of information for passengers.
