As the tenth-largest country in the world, and the largest in Africa and in the Mediterranean region, Algeria has a vast transport system which include many transport infrastructures. Algeria has two routes in the Trans-African Highway network, including the Trans-Sahara Highway, soon to be complete as a paved road running from north to south through the country. The country has also embarked (as of 2006) in the construction of a new East-West highway. Motorway network in Algeria is expanding increasingly, along with other kinds of infrastructure, though this is only true for the Northern region of the country, where most of its population lives. And this infrastructure is pretty well developed for North African standards.
