Basirat Interchange in Karaj

A glance at the map of Karaj indicates the major flaws of the city’s main road network and with regard to the population growth in the city and surrounding areas creating a continuous network is indispensable. The important point in urban transportation system in Karaj is crossing of the Tehran-Karaj-Qazvin highway from the geographic center of the city and break of links of the north and south streets of the city.

In order to organize Mallard road entrance and Shahriyar and Anbar Naft Square traffic, construction of Basirat overpass, as one of the three major intersections in this area, was essential.
