Section 10 Conclusion
2.1.1.
¡§Wan Chai Development phase II and Central-Wan Chai Bypass¡¨ and
¡§Central-Wan Chai Bypass and Island Eastern Corridor Link¡¨ (hereafter called
¡§the Project¡¨) are Designated Project (DP) under the Environmental Impact Assessment Ordinance
(Cap. 499) (EIAO). The Environmental
Impact Assessment (EIA) Reports for Central-Wan Chai Bypass and Island Eastern
Corridor Link (Register No. AEIAR-041/2001) and Wan Chai Development phase II
and Central-Wan Chai Bypass (Register No.: AEIAR-125/2008) have been approved
on 31 August 2001 and 11 December 2008 respectively.
2.1.2.
The key purpose of Wan Chai Development Phase II (WDII) is to provide
land at Wan Chai North and North Point for construction of the Central-Wan Chai
Bypass and Island Eastern Corridor Link (CWB). Land formed under the project
will be developed as a world-class waterfront promenade joining that at the new
Central waterfront for public enjoyment.
2.1.3.
There is a compelling and present need for the CWB to provide relief to
the very congested east-west Connaught Road Central/Harcourt Road / Gloucester
Road Corridor (the Corridor) which is currently operating beyond its capacity.
The CWB will provide relief to the existing congestion along the Corridor and
cater for the anticipated growth of traffic on Hong Kong Island. Without the
CWB and its access roads, there will not be sufficient capacity to serve the
heavy traffic demands at both strategic and local levels.
2.2.1.
Design and Construction of Central ¡V Wan Chai
Bypass and Island Eastern Corridor Link under the Project involves the
construction and operation of a trunk road and its road tunnel more than 800m
in length between portals that is shown at Figure 2.1.
2.2.2.
The study area encompasses existing developments from Central to North Point. The scope of the Central-Wanchai Bypass (CWB) and Island Eastern Corridor Link (IECL) includes:
¡P
A dual
three-lane trunk road, approximately 4.5 km in length, and tunnel approximately
3.7 km in length defined from the connection with the existing Rumsey Street
Flyover in Central, through to a connection with the existing Island Eastern
Corridor to the east of the Causeway Bay Typhoon Shelter (CBTS);
¡P
The
Central Interchange near the Rumsey Street Flyover to provide road connections
to the Central area;
¡P
Tunnel
control buildings and ventilation buildings;
¡P
Slip
roads to connect the CWB to the local road system in the Wan Chai North and
Causeway Bay area;
¡P
Associated
road lighting, road signing, traffic control and surveillance system; and
¡P
Other
associated works.
2.2.3.
The project also contains various Schedule 2 DPs that, under the EIAO,
require Environmental Permits (EPs) to be granted by the DEP before they may be either
constructed or operated. Table 2.1 summarises the five individual
DPs under this Project. Figure
2.1 shows the locations of these Schedule 2
DPs.

Due to the multi-contract nature of the Project, there are a number of
contracts sub-dividing the whole works area into different work areas to be
commenced. Contractors of individual
contracts will be required by the EP holder to apply Further Environmental
Permits such that the impact monitoring stations are sub-divided accordingly to
facilitate the implementation of EM&A programme and to streamline the
EM&A reporting for individual FEP holders correspondingly.

According to the Final
EM&A Report of Central Reclamation Phase III (CRIII) for Contract HK 12/02,
the major construction activities were completed by end of January 2014 and no
construction activities were undertaken thereafter and the water
quality monitoring was completed in October 2011. As such, it is considered that there were no
cumulative construction impact due to the concurrent activities of the current
projects with the Central Reclamation Phase III (CRIII) undertaken by
contractor HK12/02 in the reporting period.
7.0.3.
According
to the Final EM&A Report of EP-122/2002/E, the construction works at the
area of EP-122/2002/E were completed. In view of the above, the cumulative
construction impact due to the Central Reclamation Phase III (CRIII) was not
anticipated.
7.0.4.
According
to the construction programme of Wan Chai Development Phase II, Central-Wan
Chai Bypass and Island Eastern Corridor Link projects, no construction works
under Wan Chai Development Phase II was conducted at Wan Chai. The major
construction activities under Central-Wan Chai Bypass and Island Eastern
