The Tehran-Shomal four-lane freeway, spanning 126 kilometers, connects the metropolitan area of Tehran to the northern regions of Iran. It is one of Iran's most complex highway projects, divided into 4 sections, featuring 195 tunnels and 93 bridges, totaling 144 kilometers for the main lanes and 14 kilometers for auxiliary lanes. The project faces unique challenges posed by the special topography, geology, and tectonics of the Alborz mountain range, making the construction of diverse technical structures unavoidable.
