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 and
EP-352/2009/B) based on the Application No. VEP-409/2013 and VEP-411/2013
respectively. The environmental Permit (Permit No. EP-352/2009/C) was then
issued on 5 September 2013.
2.5

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
