The Algiers Metro (, ) is a rapid transit system that serves Algiers, the capital of Algeria. Originally designed in the 1970s, it opened in 2011 after decades of delays due to financial difficulties and security issues. The Algiers Metro was the second metro system to open in Africa, after the Cairo Metro. The first phase of Line 1, "Haï el Badr"–"Tafourah-Central Post Office", which had a length of and comprised 10 stations, opened for public service on 1 November 2011. A extension from "Haï el Badr" to "El Harrach Centre" opened for commercial service on 4 July 2015 after test runs in June. History During the 1970s, the promoters of the Algiers rapid transit subway project envisioned a network. The project was officially inaugurated in 1982, with technical studies completed in 1985. Authorities retained a German company and a Japanese specialist for building the network. The collapse of oil prices in the 1980s considerably affected the Algerian state's ability to continue funding the project. Authorities discussed the possibility of folding the subway development programme into other mass-transit projects but eventually decided to continue with the original Metro program, albeit slowly. In 1988–89, Algeria awarded construction contracts to two national companies: COSIDER and GENISIDER. Neither was experienced in running large urban transit development projects. Construction encountered financial and political difficulties, with only four stations being constructed in 15 years. Moreover, the Algiers soil is difficult to dig in, and the city's topography is irregular. Work did not advance significantly for many years. In 1994, the first long section, called Emir-Abdelkader, was completed. Another section, connecting the Central Post Office to Khélifa-Boukhalfa, was completed soon after. In 1999, the Metro of Algiers Company (EMA) invited international companies to participate in a tender offering, resulting in two new contractors being added to the project: French Systra-Sgte for project management, and Agéro-German GAAMA for construction and completion, within 38 months, of the civil engineering tasks and earthworks. In 2003, benefiting from the return of economic stability and improved security, the government increased funding and introduced a new organisational and operational structure. In January 2006, further changes were introduced to the project, with integrated systems development handed to Siemens Transportation Systems. This included the installation of fixed material, signals and electrification. Vinci was responsible for civil engineering, and the Spanish company Construcciones y Auxiliar de Ferrocarriles (CAF) was to deliver a new set of
