The 100-day drive is aimed at opening the tunnel to traffic on August 10, on time to mark the August Revolution anniversary (August 19) and the National Day (September 2).
The tunnel road stretches 13.19 kilometres from Phu Yen province’s Hao Son commune to Khanh Hoa province’s Co Ma commune. It has two bi-tube tunnels: Deo Ca (Ca Pass) tunnel (4.1 kilometres in length) and Co Ma tunnel (500 metres).

The maximum speed for vehicles traveling along the tunnels will be 80 kilometres per hour.
Construction for Co Ma tunnel has already completed.
The Deo Ca tunnel road was invested at VND15.6 trillion (US$742.8 million). Upon completion, it will shorten the distance between the two central provinces by 8 kilometres, cut travelling time by half and ensure convenient traffic between central and southern regions.
It is expected to connect Nam Phu Yen economic zone and Van Phong economic zone and contribute to the development of industry, trade and tourism in central and Central Highlands region.
