The completion of the Imamzadeh Hashem-Qazvin freeway, as one of the four main corridors of crossing the Alborz mountain range, including the road of Chalus, Haraz, Firouzkoh and Rasht, by entering the fertile and touristic area of Gilan, plays asignificant role in facilitating the transportation of goods and passengers. The length of Qazvin- Rasht freeway is about 138km, of which about 127km was built in previous years.
