The South Island Line (East) comprises a new medium-capacity partly underground and partly viaduct railway system with an approximate route length of 7km from Admiralty (ADM) to South Horizons (SOH), via three intermediate stations at Ocean Park (OCP), Wong Chuk Hang (WCH) and Lei Tung (LET). This alignment will connect the existing Island Line and future Shatin to Central Link alignments.
The new railway will run in a tunnel for a route length of about 3.5km from ADM to Nam Fung Road, then on a viaduct for about 2km past OCP, through WCH and over the Aberdeen Channel. The railway will cross the Aberdeen Channel on a bridge parallel to the existing Ap Lei Chau Bridge. From the southern side of the bridge crossing Aberdeen Channel, the railway will run in a tunnel for a route length of about 1.6km to South Horizons.
ADM, LET and SOH stations will be underground, associated with above-ground entrances and exits, ventilation shafts and plant buildings. OCP and WCH stations will be above-ground.
To minimize road-based traffic impacts, it is proposed to set up three barging points on the coast of Hong Kong Island, near the works sites, to remove the excavated materials by sea. Temporary barging points will be constructed at Telegraph Bay and Lee Nam Road for the disposal of excavated materials generated at works sites in the south of Hong Kong. Excavated materials generated at the Harcourt Garden works site will be mainly disposed of on barges that will be loaded at the Western District Public Cargo Working Area (shared use with West Island Line Project).
To enable timely delivery of explosives to works sites, a temporary explosives magazine storage site will be constructed at Chung Hom Shan.
