(EIAO). The Environmental Impact Assessment (EIA) Reports for Central-Wan Chai
Bypass and
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.
