Road transport is one of the most popular methods of cross-country freighting. Ample roads have made it possible to ship goods to virtually all corners of the country. Iran's network of roads connect Turkey, Nakhichevan, Armenia, Azerbaijan, Iraq and Turkmenistan, on the one side, to Turkmenistan, Afghanistan and Pakistan on the other.
There are 176,615 kilometres of arterial routes in Iran, 2,176 kilometres of which are four-lane highways, 816 kilometres are major freeways, 56,733 kilometres are main roads and 90,906 kilometres are byroads.
Supervised by the Organisation of State Transport and Terminals, the transport network is administered by 3,300 firms, three per cent of which are public and the remaining are owned by the private sector.
Measures are under way to increase productivity of the nation-wide transport networks. According to estimates, completion of the north-south corridor is forecast to cost one billion dollars. Meanwhile, experts say once the route is completed, it will earn the state 150-300 dollars in revenues annually.
