Sections 2 and 3 nof the freeway, with 30 percent of physical development, are still under construction, he added.
The Tehran-North Freeway mega project consists of four phases spanning 121 km in total.
Sections 2 and 3 pass through mountainous terrain, are not easily accessible and will take longer to complete.
Section-4, which is 20 kilometers long and connects Marzanabad in Kelardasht District to Chalous (both in Mazandaran), was inaugurated in March 2014.
Tehran-North Freeway is perhaps one of the most notorious projects in Iran, as it is above 20 years in the making.
