Okay, here's a revised and improved English translation, incorporating the additional details about the challenges faced during the project:
 
"Peace be upon you, and praise and thanks be to God. We have completed the largest project in the city of Baghdad: the Victory Square interchange. This involved the construction of three new tunnels, one of which runs beneath an existing tunnel, bringing the total to five tunnels. Additionally, the project includes the Qahtan Al-Dhib bridge, approximately one kilometer in length, and the Qahtan overpass.
 
This project presented significant challenges, making it one of the most complex in Baghdad. High groundwater levels and sandy soil conditions posed considerable engineering difficulties. Furthermore, Victory Square is a highly congested area due to the presence of numerous government offices and universities. Vertical excavation was required, and maintaining continuous traffic flow throughout the construction period, without halting machinery, was a major undertaking. This was achieved through the use of temporary steel bridges within the project site.
 
The work was executed by the Chinese company Trans Tech Engineering, who delivered excavation and bridge construction services to a very high standard of completion and quality. Their efforts were immense, with work proceeding day and night, even on holidays and official breaks. We are immensely proud of this achievement, particularly as traffic flow in the area was maintained throughout the 24-hour construction period. Praise and thanks be to God for everything."
