Monday, July 3, 1972
In conjunction with flyover and road construction, extensive improvements
have been made to existing trunk-sewers and new trunk-sewers laid in readiness
for further improvement in future.
Construction commenced in April 1969 and
was completed in February 1971 at a cost of HK$5.4 million.
Work on the Island connections to the tunnel began in July 1970. These
comprise two flyovers which complete the Waterfront Road/Cross Harbour Tunnel
interchange. Both flyovers are of similar construction to those constructed
previously. They were opened in April 1972 at a coat of HK$4.9 million.
Kowloon Connections
In Kowloon work on the flyover at Gascoigne Road began in the spring
of 1968 and was completed in October 1969 at a cost of HK$3.5 million. The
remainder of the works in Kowloon commenced in April 1970 and are estimated to
cost HK$15 million.
The north south route climbs from the tunnel by means of an earth-fill
embankment, which for most of its length is contained by retaining walls in
order not to impinge upon the area for the Hong Kong Technical College on the
one side, and the new Hung Hom Railway Terminus development on the other.
Special measures were taken to deal with anticipated settlements of
retaining walls due to the underlying ground conditions; an existing concrete
culvert crossing the line of the embankment, is now protected by a specially
designed structure which carries the weight of the new filling. Where the route
crosses Chatham Road, it is carried by simply-supported spans of beam and deck
slab construction on reinforced concrete columns and capping beans with piled
foundations.
