Nguyen
Dinh Bach, director of Hai Van Tunnel Management Development
Company (Hamadeco), talked with Tuoi Tre Chu Nhat (Youth Sunday)
magazine about Hai Van Pass Tunnel – an important leg of the
North-South route.
When
will you open the Hai Van Pass Tunnel for traffic?
According
to the Ministry of Transport, the tunnel is to be open for traffic
by April next year. We are now working on giving the finishing
touches.
The
tunnel will have controlling stations at the northern and southern
gates, which will also collect tolls.
All
transport will be banned from overtaking and no vehicle will be
allowed to stop or park anywhere inside the tunnel, except in the
case of a break down.
Vehicles
have to travel between 60 and 80km per hour, keeping a minimum
distance of 3m.
What
types of vehicles will be allowed to travel through the tunnel?
All
kinds of automobiles except those carrying oil, petrol, gas,
explosives and chemicals prone to fire.
Over-sized
trucks will have to inform and register with the tunnel managers,
so as to be led through the tunnel. Motorbikes of less than
175cu.cm and pedestrians will be prohibited from taking the
tunnel.
However,
to meet the demands of residents of Da Nang City and Thua Thien-Hue
Province, two vehicles will be used: one to carry people and the
other to carry their motorbikes. These vehicles will pass the
tunnel every five or 10 minutes.
We
have spent hundreds of millions of dollars to build a tunnel for
the benefit of only certain means of transport. Others will still
have to climb over the pass. Is it a waste?
The
risk of explosions and fires inside large tunnels is very high. To
ensure traffic safety, countries around the world with large
tunnels strictly obey regulations on fire and explosion
prevention. We have to also follow such safety regulations.
Motorbikes
lower than 175cu.cm and pedestrians have been banned because they
will not be able to stand the noise, heat and wind inside the
tunnel.
Japanese
experts have also asked to limit motorbikes higher than 175cu.cm
inside the tunnel.
How
do you plan to control activity inside the tunnel?
We
have installed 56 cameras at different angles. Every image will be
processed at the main control centre located at the southern gate
of the tunnel on a 75sq.m screen. Managers will monitor every
activity inside the tunnel including ventilation, dust filtering,
lighting and fire prevention systems.
The
6.3km long tunnel will be lighted with 1,000 high-voltage yellow
bulbs, which can automatically change their brightness to suit the
vision of drivers.
How
will you deal with accidents inside the tunnel?
There
will be a main control centre and a rescue centre located at the
southern gate of the tunnel. There will also be 18 fire engines
and ambulances working round-the-clock.
Along
the tunnel, we have installed fire fighting systems and scubas to
help victims.
How
many personnel will you need to manage the tunnel?
There
will be 143 engineers and technicians to manage and run the
tunnel. But to do the job effectively, we may need at least 200
people. We have sent 30 engineers to Japan to study ventilation
and electrical systems.
What
will be the toll for different categories of vehicles?
Toll
charges have not been fixed yet. But following the Ministry of
Finance’s regulations issued in 2002, vehicles with 12 seats or
less, vans with loading capacity of less than two tonnes and buses
will have to pay a toll of VND10,000. Automobiles of 12 to 30
seats and trucks with loading capacity of less 2 to under 4 tonnes
will have to pay VND15,000.
Vehicles
of 31 seats and upwards and trucks with loading capacity of less 4
to under 10 tonnes will have to shell out VND22,000. Trucks with
loading capacity of less 10-18 tonnes will be charged VND40,000
and those of above 18 tonnes VND80,000. — VNS |
