Dong Dang - Tra Linh Expressway is as beautiful as a painting before the "opening" date

From early morning, when fog was still covering the mountain slopes along the Dong Dang - Tra Linh expressway, the construction site had started a new working day, with only 2 days left, the tens of thousands of billion expressway carrying the expectation that the "beef fence" area would be opened to traffic.

The construction teams are in turn at the locations, the road rollers and asphaltvers are started, the technical staff checks the elevation and elevation of the roadbed before implementing the next items. The working atmosphere is urgent but organized, each stage is carried out in accordance with technical procedures.

When it is clear, the weather conditions are more favorable, the construction speed is accelerated. On the road, the asphalt concrete paving line operates continuously. On the slope, workers completed the reinforcement items, collected materials, and prepared the ground for the next shift.

Following the project closely from the early days as it was on the drawings, Mr. Pham Duy Hieu - Director of the General Contractor Executive Board - clearly understood the pressure of the route clearance mark. But he is also a person who often reminds engineers not to trade for quality because of progress.

Theo ong Pham Duy Hieu – Giam doc Ban dieu hanh Tong thau du an, muc tieu thong tuyen dung thoi han la yeu cau quan trong, song khong vi ap luc tien do ma bo qua cac yeu to ky thuat. “O mot so doan nen duong dap cao toi 20m, du da dat K98 va du dieu kien de tham lop base hoac thong tuyen tren be tong nhua, chung toi van tiep tuc theo doi do lun. Chi khi cac thong so on dinh moi trien khai cac lop mat duong hoan thien de bao dam chat luong lau dai cua tuyen cao toc”, ong Hieu cho biet.

According to Mr. Pham Duy Hieu, the goal of opening the route on time is an important requirement, but not ignoring technical factors due to progress pressure. In some sections of the roadbed is up to 20m high, although it has reached K98 and is qualified to be paved with a base layer or a route is cleared on asphalt concrete, we continue to monitor the subsidence. Only when the parameters are stable will the road surface layers be completed to ensure the long-term quality of the expressway.

According to the General Contractor's representative, on this expressway, the two tunnels That Khe and Dong Khe are the largest technical bottlenecks. These days, at That Khe tunnel (Lang Son), workers are carefully completing every last detail, from the substrate outside the tunnel shell to the tunnel cleaning and technical system checking.

More than 20km away, Dong Khe tunnel (Cao Bang) is in a similar situation. The retaining walls, drainage systems, mechanical roofs, and square areas are constantly inspected.

The Dong Dang - Tra Linh Expressway has a total length of 121 km, divided into 2 investment phases with a total investment of nearly VND23,000 billion. Stretching through Lang Son and Cao Bang, phase 1 of the project is over 93km long, including 64 overpasses across the Ky Cung and Bang Giang rivers along with countless streams and provincial roads.

In 2025, the project will continuously suffer from major storms and floods. At one point, floodwaters swept away materials, causing landslides on the roadbed, causing tens of billions of VND in damage. From the site handover milestone at the end of March 2025, the actual construction time is only about three months.

Before the December 19 milestone, more than 3,000 officers, engineers and workers of the project persistently stayed on hundreds of construction sites to drill mountains and open roads. Up to now, the output value has reached VND 6,219/6,828 billion, equivalent to more than 91% of the plan to open the route in phase 1.

Before the Lunar New Year 2026, the project strives to open the route on the asphalt concrete layer for about 44 km, open the route on the crushed stone aggregate level for about 45 km, the rest are the sections K95 and K98.

Mr. Nguyen Duc Tuan, Deputy General Director of Dong Dang - Tra Linh Expressway Joint Stock Company, said that units are taking full advantage of favorable weather conditions, increasing personnel to complete the paving of about 7 km of asphalt concrete road surface in Cao Bang province before December 19.
