    One of the most complex items currently is the construction of the underpass section under the railway. The last three closed tunnels are directly related to the railway system, requiring the construction process to ensure safety for the works below, while maintaining stability on the railway tracks above, without disrupting train operations.

    Kim Dong - Giai Phong underpass is designed with four motorized lanes. Along with that, the Ring Road 2.5 project, Dam Hong - National Highway 1A section, is also being implemented. When these projects are completed and put into synchronous operation, it will contribute to reducing congestion, improving traffic capacity and strengthening connectivity at the gateway to the Capital.
