The project spans a total length of 18.69 km, traversing a coastal area marked by complex geological and hydrological conditions, along with tidal influences.
In the first phase, the road was constructed with a 4-lane surface, a 6-lane subgrade, and a designated speed limit of 60 km/h. In the second phase, the road was widened to 6 lanes, incorporating sidewalks, a vertical drainage system, and consistent tree planting and lighting installations along the entire route.
The Ha Long–Cam Pha coastal road features two bridges and a unique 235 m mountain tunnel, designed in two segments and including 3 lanes each. This scenic coastal route balances mountain and sea views, enhancing tourism, commerce, and urban development in Ha Long and Cam Pha cities.
Transport Engineering Design Inc. (TEDI) is responsible for the following consulting services on this project:
- Developing the design concept
- Conducting feasibility studies
- Executing detailed design plans
With nearly 60 years of expertise, TEDI has introduced specific design innovations for the seawall connecting Ha Long to Cam Pha:
- Route Planning: Aligns with local landscape planning to preserve natural views and minimise environmental disruption.
- Longitudinal Profile Design: The profile is aligned with the designated water level, blending horizontal and vertical curves to ensure safe, efficient travel, and to meet approved project standards. This approach also minimises the need for extensive excavation, backfilling, and auxiliary work.
Award-Winning Innovation, Quality, and Professional Excellence in Landscape Architecture. The Ha Long–Cam Pha coastal road project traverses stunning natural landscapes of rocky mountains and coastline, blending seamlessly with the area’s natural features. The design harmonises plan elements, longitudinal profiles, and horizontal curves to align with the region’s topography, minimising land clearance requirements. Once opened, the road integrates smoothly into the surroundings, playing a vital role in boosting tourism without disrupting the natural landscape.
In rock excavation areas, reinforced concrete frames and steel nets secure the talus slopes, preventing rock falls and ensuring safety during construction. Tunnel alignments were strategically selected to reduce rock blasting and maximise the route’s utility. Excavated rock is repurposed to fill subgrades in tidal zones, while elevated stone embankments accelerate construction time by reducing tidal impacts and expediting project progress.
To enhance durability, all work elements incorporate high-grade concrete and sulfate-resistant cement, designed to withstand environmental factors and ensure the structure’s longevity.
