This four-lane freeway, approximately 23 kilometers in length, was constructed in the rugged mountainous terrain of the eastern Alborz Mountains, extending from the end of Babaei Highway to the western outskirts of Bumehen. The project was completed at an estimated cost of 1,800 billion Rials.

It is regarded as one of the most successful freeway projects in the country, due to its contribution to improved traffic flow, significant reduction in travel time, and effective traffic redistribution, along with increased revenue from toll collection.

For its role in conducting engineering studies and construction supervision, Iran Oston Consulting Engineers was honored with the title of Top Consultant at the 18th National Conference of the American Concrete Institute (ACI) – Iran Chapter in February 2015.
