2.1
The proposed Hong Kong - Zhuhai - Macao
Bridge Hong Kong Link Road (HKLR) is 12km long connecting the Hong
Kong-Zhuhai-Macao Bridge (HZMB) at the HKSAR Boundary with the Hong Kong
Boundary Crossing Facilities (HKBCF) situated at the north eastern waters of
the Hong Kong International Airport, opening a new and direct connection route
between Hong Kong, Macao and the Western Pearl River Delta.
2.2
The HKLR comprises a 9.4km long viaduct
section from the HKSAR boundary to Scenic Hill on the Airport Island; a 1km
tunnel section to the reclamation formed along the east coast of the Airport
Island and a 1.6km long at-grade road section on the reclamation connecting to
the HKBCF. The tunnel section of HKLR will pass under Scenic Hill, Airport Road
and Airport Railway to minimize the environmental and visual impacts to Tung
Chung residents.
2.3
An application (No ESB-110/2003) for an
Environmental Impact Assessment (EIA) Study Brief under Section 5(1) of the
Environmental Impact Assessment Ordinance (EIAO) was submitted by Highways
Department (the Project Proponent) on 8 October 2003 with a Project Profile
(No. No. PP-201/2003) for the Hong Kong - Zhuhai - Macao Bridge Hong Kong
Section and North Lantau Highway Connection. The Hong Kong - Zhuhai - Macao
Bridge Hong Kong Section and North Lantau Highway Connection has subsequently
been renamed as HKLR. EPD issued an
EIA Study Brief (No: ESB-110/2003) in November 2003 to the Project Proponent to
carry out an EIA study.
2.4
An EIA Study (Reg. No. AEIAR-144/2009) has
been undertaken to provide information on nature and extent of environmental
impacts arising from the construction and operation of HKLR. The Environmental
Permit was issued on 4 November 2009 (Permit No. EP-352/2009). Pursuant to
Section 13 of the EIAO, the Director of Environmental Protection amends the
Environmental Permit (No. EP-352/2009) based on the Application No.
VEP-339/2011 and the environmental Permit (Permit No. EP-352/2009/A) was issued
on 9 November 2011 for HKLR to the Highways Department as the Permit Holder.
Subsequently, the Director of Environmental Protection amends the Environmental
Permits (No. EP-352/2009/A, EP-352/2009/B, EP-352/2009/C) based on the
Application No. VEP-409/2013, VEP-411/2013 and VEP-459/2014 respectively. The
environmental Permit (Permit No. EP-352/2009/D) was then issued on 22 December
2014.
2.5
Figure
1a-d shows
the layout of the Contract and the scope of the Contract works
comprises the following major items:
·
a
dual 3-lane carriageway in the form of viaduct from the HKSAR boundary
(connecting with the HZMB Main Bridge) to the Scenic Hill (connecting with the
tunnel under separate Contract No. HY/2011/03), of approximately 9.4km in
length with a hard shoulder for each bound of carriageway and a utilities
trough on the outer edge of each bound of viaducts;
·
a grade-separated turnaround facility located
near San Shek Wan, composed of sliproads
in the form of viaduct with single-lane carriageway bifurcated from the HKLR
mainline with an elevated junction above the mainline;
·
provision of ancillary facilities including,
but not limited to, meteorological enhancement measures including the
provisioning of anemometers and modification of the wind profiler station at
hillside of Sha Lo Wan, provisioning of a compensatory marine radar, and
provisioning of security systems; and
·
associated civil, structural, geotechnical,
marine, environmental protection, landscaping, drainage and highways electrical
and mechanical (E&M) works, street lightings, traffic aids and sign gantries,
marine navigational aids, ship impact protection system, water mains and fire
hydrants, lightning protection system, structural health monitoring and
maintenance management system (SHM&MMS), supervisory control and data
acquisition (SCADA) system, as well as operation and maintenance provisions of
viaducts, provisioning of facilities for installation of traffic control and
surveillance system (TCSS), provisioning of facilities for installation of
telecommunication cables/equipments and reprovisioning works of affected existing
facilities/utilities.
