NOISE BARRIERS FOR THE TOLO HIGHWAY WIDENING PROJECT

Tolo Highway is part of the major highway serving the Northeast New
Territories (Note 3). Since its opening in 1985, the volume of traffic on Tolo Highway has steadily increased. In 1996, the Highways Department (HyD) commissioned a feasibility study on the widening of Tolo Highway (the section between Island House Interchange at Tai Po and Ma Liu Shui Interchange at Sha Tin) to cope with the
increasing traffic demand. As part of the feasibility study, the HyD’s consultant conducted an EIA study.

Recommendations of the Tolo Highway EIA study. In April 1997, the HyD’s consultant completed the Tolo Highway EIA. In May 1997, the Advisory Council on the Environment endorsed the EIA study report. The study report recommended the following measures to reduce the road traffic noise impact to within the limits stated in the Hong Kong Planning Standards and Guidelines:
(a) the adoption of low noise road surfacing on the whole road widening section;
(b) the installation of noise barriers (ranging from 1.5-metre to 8-metre high) at road kerb and the central median; and
(c) the setting back of buildings (i.e. positioning them farther away from Tolo Highway) and the use of special building design at the planned residential and institutional uses in the PSK reclamation area to deal with the residual traffic noise impact.

Noise barriers for planned residential developments in PSK
2.8 The PSK reclamation area covers an area of about 70 hectares along the waterfront of Tolo Highway. The Civil Engineering Department (CED) is responsible for forming the area using public filling materials by stages from 1996 to 2003. 2.9 In 1996, the Committee on Planning and Land Development endorsed an
action area plan to provide the basis for undertaking the planning and feasibility study for PSK. The plan outlined the broad land uses for the PSK reclamation area, which included a Science Park in the south, residential developments in the north and recreational uses in the middle.

Noise barriers planned for PSK reclamation area. In January 1997, the EIA working group decided that the Tolo Highway EIA study should assess the noise impact on the potential residential developments in the northern part of the PSK reclamation area based on the PSK action area plan. The Tolo Highway EIA study, which was completed in April 1997, allowed for the provision of 320 metres of noise barriers on the southbound carriageway for protecting the planned residential developments in the PSK reclamation area (Note 8).
