The expressway passing through Khanh Hoa - Ninh Thuan - Binh Thuan, officially opened to traffic, making travel from Ho Chi Minh City to the coastal provinces of the South Central region more convenient and faster.

The Cam Lam – Vinh Hao section is one of three component projects invested in the form of public-private partnership.

The project has a total investment of VND8,925 billion, with a length of 78.5km, passing through Khanh Hoa, Ninh Thuan and Binh Thuan. The investor consortium includes Deo Ca Group, Deo Ca Construction Company and Construction Investment Corporation 194.

The Cam Lam – Vinh Hao Expressway has been completed with 70 km of roadway, 35 bridges, two interchanges, 69 km of frontage roads, 2.25 km of mountain tunnel, together with equipment and the ITS system. The project’s acceptance results have been approved by the State Council for Acceptance of Construction Works.

Vietnam Road Administration agreed that Deo Ca Transport Infrastructure Investment Joint Stock Company (HHV) is the unit that manages, operates and maintains the project to ensure it is put into safe and smooth operation.

On the route, there is the Nui Vung tunnel, 2.2km long, with three lanes and a tunnel width of 14m. Phase 1 uses a right-hand tunnel for two-way traffic. This is the fourth largest road tunnel in the country after the Hai Van, Deo Ca and Cu Mong tunnels, built by the Deo Ca Group.

To carry out the project, the joint venture had to overcome many difficulties in a place with a year-round hot climate, having to pull electricity and water from areas with difficult and complex terrain...

The project implementation time was also the time when the Covid-19 epidemic broke out strongly, but with the spirit of working "through the night, through holidays, through the epidemic", Deo Ca Group increased recruitment and training of local human resources, made efforts to mobilize thousands of personnel, machinery, equipment, and arranged project construction teams.

After overcoming the "pandemic storm", the project faced a "material price storm". The project management board proactively proposed to supplement the material mine according to a special mechanism, combined with the use of agricultural land for renovation, and timely use of tunnel excavation stone to serve the construction.

Implementing the Prime Minister's direction with the spirit of "overcoming the sun, overcoming the rain", "eating quickly, sleeping urgently", "only working, not thinking about retreating"... the Deo Ca - 194 investor consortium led by Deo Ca Group and construction contractors gradually overcame difficulties, applying the initiative of the fake reverse arch method to overcome weak geology.

At the same time, organize scientific construction, control project progress and costs with new technology such as biometric facial recognition for personnel management, electronic scales for material control, BIM technology for quality management, and increase construction steps to compensate for progress.

After 30 months of construction, the expressway was officially approved on April 26, 2024 to serve increased demand during the holidays.

This is a highway with an Intelligent Transportation System (ITS), temporary rest stops on the route and an operational management team that has been completed in sync with the project.

In which the clusters ITS equipment and cameras along the route are arranged to operate on solar energy, saving power consumption, reducing costs and protecting the environment.

ITS system including CCTV and incident detection cameras, UHF radio communication system and loudspeakers (PA, digital transmission (DTS), electronic information boards and signal lights (VMS & SS), Tunnel Control Center…

This system is a part of the expressway project, aiming to enhance the connectivity between people, vehicles and expressway infrastructure to optimize operational efficiency, ensure smooth, safe, efficient, convenient and environmentally friendly traffic, especially meaningful in handling incident situations.

The camera system on the route is equipped with two types: surveillance cameras (CCTV) and cameras integrated with vehicle detection systems (VDS).

These types of cameras use the most advanced specialized AI image processing technology and are also supported by peripheral devices such as infrared and radar.

PTZ cameras can rotate 360 ​​degrees, ensuring full-line observation without blind spots; VDS cameras are integrated with AI with functions such as vehicle classification, license plate recognition, detection and warning of incidents such as speeding, traffic congestion, stopped vehicles, wrong lane driving, going in the opposite direction, and objects falling on the road.

In addition, the project investor proactively spent money to build temporary rest stops along the route to serve people for free while waiting for the Ministry of Transport to approve the investment in building official rest stops.

The temporary rest stop was built in just 20 days, with clean restrooms, electricity, air conditioning, and a nearly 300m deep well drilled to overcome water source difficulties and provide free service to people traveling through the route.

Cam Lam – Vinh Hao Expressway was put into use, connecting the expressway from Ho Chi Minh City to Nha Trang, helping to reduce half the time compared to National Highway 1, contributing to the completion of the North – South expressway system, creating an important driving force to promote socio-economic development for the country.
