Table 2.1 Summary of Engineering Assessment

Comparison

1.

Alteration to the proposed EHC

arrangement.

Scheme I (Figure No. D4)

1. Does not propose any

alternation of the EHC layout but indicates provision of additional links.

Scheme II (Figure No. D5)

1. Proposes substantial

modification of the EHC layout with additional links and structures. Major alteration of the Sai Wan Ho/Kornhill Interchange is required.

Scheme III (Figure No. D6)

1. Proposes minor modification of the EHC layout with additional links. Major alteration of the Taikoo Shing Interchange is required.
