With a mile long line of stopped traffic, the atmosphere in the tunnel
would become stifling in spite of the ventilation system, Mr. May explained.
When plans for the Lion Rock Tunnel were first conceived, it was
intended to be an economical route for conveying water from the Sha Tin filters
of the Plover Cove Water Supply Scheme to the urban areas of Kowloon.
In 1960, it was decided that the proposed tunnel cross-section should
be enlarged to provide space for an additional road link between Kowloon and
Sha Tin.
The tunnel is 4,677 feet long, with a minimum head-room of fifteen-
and-a-half feet capable of accommodating double-deck buses and other heavy
commercial vehicles.
Traffic warning signs, carbon monoxide detectors, visibility meters,
fire fighting equipment and emergency telephones have also been installed in
the tunnel.
The tunnel was opened by Sir David Trench on November 14, 1967 at a
ceremony held at the tunnel's Administrative Building.
To commerorate the fifth anniversary of the Lion Rock Tunnel, the staff
will be holding a small dinner party in the Administrative Building tomorrow
(Tuesday) evening.
