Light-weight transparent materials for flyoous with high volume
of traffic
11. MR! CHEONG-LEEN asked:
Question No.11
WRITTEN REPLY BY THE SECRETARY FOR HEALTH AND WELFARE TÓ A QUESTION BY THE HON HILTON CHEONG-LEEN
IN THE LEGISLATIVE COUNCIL ON WEDNESDAY 6 JULY 1988
Question: The Environmental Protection Department has
proposed to experiment with light-weight
transparent material to cover flyovers carrying high volume traffic which are close to residential buildings in order to reduce the noise effect on residents. Will Government inform this Council whether the experiment has been completed, and if so what conclusions have been drawn; if not, when will the experiment be completed?
SECRETARY FOR HEALTH AND WELFARE:
Sir,
the Environmental Protection Department has
proposed that light-weight transparent covers should be
considered for flyovers carrying a high volume of traffic
close to residential buildings. Such a measure would be
effective in reducing the noise problem and is likely to be
more attractive than concrete covers. The practicability
and feasibility of such designs are being reviewed by the
administration, but an actual experiment has not yet been
conducted.

However, it has been agreed that two elevated
sections of the Tate's Cairn Tunnel approach roads near Choi
Hung Estate and Richland Gardens in Kowloon should be
constructed with noise reducing enclosures, and plans are in
hand to evaluate whether these enclosures could be made of
light-weight transparent materials. The Environmental
Protection Department is considering this matter together
with Highways Department.
