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.

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
