The Nui Vung Tunnel, a vital component of the Cam Lam-Vinh Hao Expressway project in south-central Vietnam, has been successfully excavated after nearly 18 months of construction.
The Cam Lam-Vinh Hao Expressway Joint Stock Company and Deo Ca Group held a ceremony in Nhi Ha Commune, Thuan Nam District, Ninh Thuan Province on Monday to commemorate the successful excavation of the Nui Vung Tunnel.
The excavation teams from both the north and south directions of the left branch of the tunnel successfully dug through Vung Mountain with exceptional accuracy, marking a significant milestone in the project’s progress.
The tunnel, stretching 2.2 kilometers in length and located within the Cam Lam-Vinh Hao Expressway project, is built in the New Austrian Tunneling Method (NATM), an engineering technique that provides flexibility in construction across different geological conditions and guarantees improved safety compared to conventional tunneling modes.

As a whole, the Cam Lam-Vinh Hao Expressway project will reduce travel time, catering to the requirements of travel, transportation, tourism, cultural and social exchanges, boosting regional economic development and tapping into the region’s tourism potential.
