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 1980’s 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.
Metro works seven days a week, from 5:00 to 23:00. This schedule is shortened during the holy month for Islamic population: Ramadan. When this happens, the Subway of Algiers only operates from 7:00 to 13:30.
