In line with the contract for the executive operations of the western tunnel in the second area of ​​the North Tehran Freeway, based on the reports and field controls carried out, we would like to inform all stakeholders that despite the difficulty of the executive operations in the western Alborz tunnel due to reasons such as the complexity of the geological conditions, the variety of natural hazards, the limitations resulting from the proximity to the eastern runway that is under operation, and its slag and excessive length, the excavation of the top section in Ordibehesht 1404 was recorded at 61 meters on the northern front, 101 meters on the southern front, and a total of 162 meters, which is remarkable and honorable in its own right. In this regard, while appreciating and thanking the efforts and perseverance of the project's agents and other pillars, we congratulate the success achieved and wish it to continue.
