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

bound of carriageway and a utilities trough on the outer edge of each bound of
viaducts;
¡P

Temporary storage of long span segments:
-
3 barges have been unloaded at CCCC4 yard. 2 barges
remain with long span stored with P20 +1, +2. These barges will not unload at
CCCC4 and the segments will remain stored on the barges until required for
delivery to Hong Kong which is estimated to be mid to late September 2015.
(d)
General:
-
Delays in the segment unloading continue to impact
on the delivery cycle to the extent that there are number of barges overstayed
for 14 days in Hong Kong.
-
Loading and unloading was impacted by inclement
weather (typhoon and heavy rain events).
-
It has been necessary to deploy 2 additional barges
to columns delivery in order to overcome storage issues and potential stoppages
at MBEC precast yard.
