Near Nisur Square in the center of Baghdad, the capital of Iraq, two cranes are steadily placing a 30 meter long and approximately 31 ton prefabricated beam onto a newly constructed bridge pier. The early morning in Baghdad in March was still a bit chilly, but the construction site was a bustling scene.

At this moment, Guo Xiaowei, the general manager of the Baghdad Nisur three-dimensional transportation hub project undertaken by Sichuan Railway International Economic and Technological Cooperation Co., Ltd. (Chuantie International), was wearing a safety helmet and holding the design drawings, watching every step of the beam erection progress.

The Nisur three-dimensional transportation hub project started construction in July last year and is expected to be completed in January 2025. The project includes a four story structure consisting of bridges, ground roads (railways), tunnels, and underpass tunnels, with the underpass tunnel reaching a maximum depth of 24 meters. After the completion of the project, it is expected to significantly alleviate traffic congestion and noise pollution in the core area of Baghdad.

Chuantie International has proposed a three-dimensional transportation solution of "2 elevated roads+5 tunnels" for this purpose. We need to act like surgeons, skillfully constructing 'heart bridges' in the' heart area 'of the capital's transportation, to alleviate the' traffic obstruction 'problem that troubles Baghdad, "said Guo Xiaowei.

The Nisur project will also carry out relocation and renovation of old underground pipelines and cables in the surrounding area. After completion, it will significantly enhance the municipal public service capacity of the surrounding area and effectively improve local livelihoods.
