CONSTRUCTION OF SECOND LION ROCK TUNNEL
Construction of the dual-purpose Second Lion Rock Tunnel will
begin soon as tenders are now being called for the project.
It is an enlarged waterworks tunnel required for the High Island
Water Scheme to convey increased water output from Sha Tin to the urban areas.
The tunnel will also handle the increasing volume of traffic
travelling to the New Territories.
This is expected to further increase with
the development of Sha Tin new town and the construction of a new race course.
The Second Lion Rock Tunnel, about a mile long, will be similar to
the existing one with internal dimensions of 30" 4" by 291 6". Two 60-inch
diameter water mains will be laid in the tunnel.
Construction work consists of tunnel driving, concrete lining,
portal works, the laying of mains, formation of approach roads and associated
drainage works.
The project is expected to start by the end of this year and will
take about 30 months to complete.
A spokesman for the Public Works Department said: "Although the
works are unlikely to cause nuisance to residents nearby, noise level will
be kept to a minimum.'
On completion, the lined tunnel will be handed over to the Highways
Office to provide the road slab, ventilation, lighting and other ancillary
works for the road tunnel.
