New metro, new connections for the city of Algiers

4 June 2014

The city of Algiers is undergoing deep transformation. The capital of Algeria has begun to develop a public transport system on a par with its size and population of over 6 million. The metro, opened in late 2011, is in full expansion with LafargeHolcim on board!


As in many rapidly growing cities, traveling by car in Algiers is often difficult. The first metro project dates back to... 1928! But it was not until 1981 that the project was launched, and 2011 that the Algerian capital has become the first city in the Maghreb with a metro - and the second in Africa after Cairo.

This time, the movement is well underway. Right after the inauguration of the first 9.5km stretch, the city launched three extensions totaling 9.2 km. They will connect the inner-city neighborhoods - including the Casbah and part of Bab El Oued - with the densely populated suburban areas, underserved today.

LafargeHolcim concrete to connect neighborhoods of the city

LafargeHolcim is present on this major project through various high-quality concretes:

  • shotcrete (partly fiber-reinforced) for the reinforcement of the excavation,
  • wallfill concrete,
  • concrete for the foundations and the roof - part of which is our fluid and fast-setting concrete Chronolia®.

And this is only the beginning: new extensions of Line 1 are under investigation and, eventually, two other lines will be added to connect the eastern, southern and western suburbs, and the city ​​Airport. In 2025, the metro network will reach 55 km and 50 stations to serve the entire Greater Algiers.

This major project plays an important part in a vast urban renewal project, which is expected to change the face of the Algerian capital and improve the lives of its inhabitants.
