Project on Improving Safety of Railway Bridges on Hanoi - Ho Chi Minh City Route (abbreviated as 44-bridge project) is invested by the Ministry of Transport, the PMU is the representative of the investor using the ODA loan of the Japan International Cooperation Agency (JICA) and the reciprocal capital of the Government of Vietnam. The project has a total investment of 37.153 billion Japanese yen and 1,054 billion dong (equivalent to 9,284 billion dong), including a restoration of 44 bridges (with a total length of 6,553 m) and 45,078 km of railway on two sides of bridges; upgrading, renovating and restoring 22 crossroads; newly built 03 underpasses and 24 box culvert underpasses; upgrading, renovating and restoring 15 bridge underpasses; newly built two overpasses at the south of Ninh Binh railway station and south of Do Len bridge; newly built Ninh Binh Railway Station; Procurement of 12 types of machinery, equipment for maintenance and renovation of bridges and railways. The 44-bridge project was approved by the Ministry of Transport Decision No. 1888/GTVT-KHDT dated 25/6/2004 and was amended in Decision No. 4149/QD-BGTVT dated 28/12/2007 and Decision No. 1488/QD-BGTVT dated 26/06/2012. The investment objective of the project is to improve the safety of the railways in the process of operation and exploitation; improve the safety of other traffic activities and livelihoods on both sides of the railway within the project; shorten the journey of trains on the Hanoi - Ho Chi Minh City rail route. The project has 12 ODA packages, including 09 construction and installation packages, 02 consultancy packages and 01 procurement package. Bidding packages using counterpart funds were tasks serving major construction and installation items of the project such as site clearance, demining, relocation of railway signaling system and building insurance. The technical designs of the 44-bridge projects was formulated and approved between 2005 and 2010. The project applied many new technologies, the first of which was applied on Vietnam's railways such as continuous welded rails, continuous welded rails directly connected on the steel beam, prestressed reinforced concrete rail bridge using cantilever technology with rails connected to concrete beam by special bonding system without using Ballast stone which helps trains with smooth running and less shake. Regarding some connecting roads at two sides of bridges, weak grounds were solved by CDM-LODIC cement piles using Japanese technology. These new technologies were first applied to the bridges on the Hanoi-Ho Chi Minh City railway. Construction phase of the project was started from the end of 2010 to the end of 2015; during that period: Ba Bau bridge in Quang Nam province was the first bridge of the project to be completed and open on 10/10/2011 and Thap Cham bridge in Ninh Thuan province is the last bridge of the project to be completed and open on 25/12/2015.
