The application of Circular No. 35/2016 / TT-BGTVT dated November 15, 2016 to calculate the financial plan of the road tunnel project of the Ca Pass is inappropriate:

The price of the Ministry of Transport is applied to all BOT roads and bridges (not provide maximum price for services using road tunnels), regardless of bridges, tunnels, lengths of works, e-commerce, quality of services ...

Road Tunnel is a type of works with a higher investment capital compared to other forms of transport, and people have options (crossing the tunnel has to pay fees, crossing the pass does not have to pay fees). Therefore, the calculation of the rate of return in PATC of the Ca road investment project (including Ca and Co Ma tunnels, Cu Mong l and Hai Van tunnels) are being controlled by unreasonable ceiling level and without basis for application.

When comparing the total capital investment in  the tunnel of the Deo Ca project is about 12,800 billions, more than 10 times the total investment of Phu Gia - Phuoc Tuong tunnel that is about 1200 billions but the current revenue is about VND 700 million/day and when comparing to the total investment of the road and bridge projects show that the inadequacies in current prices are unreasonable.
