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.
