According to Project Management Board 4 (Vietnam Road Administration), the railway overpass is designed to be a permanent structure constructed of steel, reinforced concrete, and prestressed reinforced concrete. The bridge is classified as a Class III structure, with a grade-separated crossing. The overpass has a 12m wide cross-section; the minimum clearance height over the railway is over 6m. The total length of the bridge, including the abutments, is 167.14m.
Regarding the approach road to the bridge, the M1 abutment has a retaining wall with a length of 117.2m; the M2 abutment has a retaining wall with a length of 114.78m. The access roads on both sides of the retaining wall have a width of 5.4m and 3.5m, the road surface is asphalt concrete. The total length of the bridge and approach road is 399.12m.
Some people affected by the project in Binh Quy commune requested not to build a railway overpass, but only to widen the road across the railway (at-grade intersection).
Meanwhile, the investor's representative explained that the railway overpass at km15+615.32 on National Highway 14E is a Class III road bridge, the same class as the road section from km15+270 to km16+054. Therefore, according to Clauses 2 and 3 of Article 17 of the Railway Law No. 06/2017/QH14, railway crossings with roads must have grade-separated interchanges in the following cases: railways with a design speed of 100 km/h or more crossing roads; railway crossings with roads of Class III or higher; railway crossings with urban roads; urban railway crossings with roads, except for tram tracks.

According to the Railway Law, investors building new railways must be responsible for building grade-separated intersections as prescribed in Clauses 1 and 2 of Article 17; investors building new roads must be responsible for building grade-separated intersections as prescribed in Clause 2 of this Article.
Therefore, the construction of a railway overpass is mandatory when upgrading and renovating National Highway 14E. Furthermore, the railway overpass will replace level crossings. This will avoid intersections between roads and railways, preventing traffic safety hazards, and improving the efficiency of train speeds and vehicle traffic on the road. It will facilitate the transportation of goods by both road and rail, contributing to socio -economic development and ensuring national security and defense.
Mr. Que Hai Trung, Deputy Director of Project Management Board 4 (Vietnam Road Administration), shared that the project to renovate and upgrade National Highway 14E is being implemented using medium-term capital for the period 2021-2025. The investment plan for the railway overpass cannot be changed. If the overpass is not completed by 2025, the Ministry of Transport will withdraw the funding.
According to experts, the overpass will impact and disrupt the people living nearby. However, when the project is completed and put into use, it will bring great benefits to the community, such as developing urban infrastructure, ensuring traffic safety for roads and railways.
Without an overpass, residents living near the railway will suffer severe long-term pollution from dust and noise as the number of vehicles, especially trucks and buses, increases on National Highway 14E. People commuting to work will waste a lot of time waiting for trains to pass. Furthermore, critically ill patients being transported to the area may have to stop if a train is in motion, missing a crucial opportunity for life-saving treatment.
