The Deo But tunnel project in Deo But mountain is located in the territory of two communes Ky Hoa (Ky Anh town) and Ky Lac (Ky Anh district, Ha Tinh). This project belongs to the Vung Ang (Ha Tinh) - Bung (Quang Binh) expressway section. Deo But Tunnel is nearly 1km long, with a total investment of over 1,100 billion VND. This is the only road tunnel in the more than 107km long North-South Expressway in the East through Ha Tinh. The project is invested by Project Management Board 6 (Ministry of Transport) and constructed by Son Hai Group. According to engineers, the project will officially start in July 2023. After more than 10 months of construction, the right branch of phase 1 of the project, 840m long, will officially open to traffic on the occasion of the 134th anniversary of Uncle Ho's birthday (May 19). The left tunnel is expected to open next July.
During the past time when constructing the tunnel, the construction unit encountered many difficulties due to a lot of underground water and loose interspersed rocks. To overcome this, the units agreed on a series of solutions such as strengthening the supporting structure, constructing an inverted arch and working 3 shifts, 4 shifts/day, during holidays and Tet to make up for the progress. In late June, the construction unit is implementing the construction of the tunnel's support structure and the remaining items for the right branch. For the left pipe branch, engineers and workers are speeding up the construction to clear the tunnel.
At the Deo But tunnel construction site, there are always dozens of workers, engineers, and modern machinery and equipment, including robots working non-stop. Thanks to the robot arms, the operators can easily operate to reinforce the tunnel arch. The representative of the construction unit also said that up to now, the Deo But tunnel has completed about 50% of the volume, ensuring the set progress. Deo But Tunnel is designed with 2 tunnels with lengths of 716m and 840m respectively. Each tunnel is 8m high, 15m wide, has 3 lanes with expansion points to prevent incidents during use and an internal lighting system. This project is expected to be completed in December 2025, at the same time as the Vung Ang - Bung expressway section. The North - South expressway in the East phase 2021-2025, the Vung Ang - Bung section is more than 55km long, with a total investment of 12,548 billion VND, passing through two provinces of Ha Tinh (12.9km) and Quang Binh (42.44km).
