The country of the Islamic Republic of Iran with an area of 1,648,000 square kilometers, common borders with 7 countries and having access to the Caspian Sea in the North and the Persian Gulf and the Sea of Oman in the South, is the second vastest country in the Middle East. In addition to the vastness of the area, being on the route of international rail, highway and freeway corridors has caused Iran to play an important role in the transportation network of the Middle East. Therefore, with the purpose of concentrated management in the field of construction and development of transportation infrastructure, formation of a structural coherence and bolstering strategic affairs of the country’s transportation management, the specialist parent company of construction and development of infrastructure of the country was founded in 2005. This company, as the main authority for transportation infrastructures, is one of the components of the Ministry of Road and Urbanization.
