The roadbed is 26m wide, with 24.5m of road surface, including 4 lanes (2 emergency stops). The finishing stage will be 6 lanes with a speed of 120km / h.
The 540m tunnel project (in Hoa Vang, Da Nang) is designed as two separate tunnels between the departure and arrival directions; 102 large bridges with a length of nearly 9km; 9 intersections, drainage system ... Total investment project is nearly 28,000 billion.
This is the first expressway project in the Central Region, which is owned by VEC, the North-South Expressway section of the East, as part of the development plan for Vietnam's expressway network up to 2020. And orientation to 2030.
