In 2008, Algeria's nationally owned railway had about 3,973 km of track. The system consists principally of a main east-west line linked with the railways of Tunisia and Morocco and of lines serving the mining regions of Béchar (formerly Colomb Béchar); the esparto grass country on the High Plateaus; the date-producing areas of Biskra, Touggourt and Tebessa; and the main port cities.
Roads are most adequate in the Tell zone; in the mountainous and rural areas, they are relatively poor. In 2010 there were 113,655 km of roads, of which about 87,605 km were paved. The French colonial administration built a good road system, partly for military purposes, which after independence was allowed to deteriorate to some extent. However, new roads have been built linking the Sahara oil fields with the coast. Algeria's portion of the trans-Saharan highway, formally known as the Road of African Unity, stretching about 420 km from Hassi Marroket to the Niger border south of Tamanrasset, was completed in 1985.
Algiers is the principal seaport. Other significant ports are Arzew, Bejaïa (Bougie), Skikda (a large gas-exporting centre also known as Philippeville), Oran, Annaba, Ghazaouet and Mostaganem. In 2010, Algeria's merchant fleet numbered 38 ships of 1,000 GRT or over.
An extensive air service uses 157 airports and airstrips, of which 64 have paved runways in 2013. The main international airport, H. Boumediene Airport, is about 20 km from Algiers. Constantine, Annaba, Tilimsen (Tlemcen) and Oran have smaller modern airports that can accommodate jet aircraft. Air Algérie, the national airline, provides international service. In 2003, a total of about 3.293 million passengers were carried on domestic and international flights.
