Cross-harbour tunnel

road connections

Part II - Kowloon Peninsula

AT ITS north end on Victoria Island the Hong Kong cross-harbour tunnel emerges on to reclaimed land. And so, though the planning of the road con- nections was complex, the consultants had the advantage of working with a virgin site.

At the south end of the tunnel, at Hung Hom in Kowloon, no such re- claimed land was available and plan- ning was made even more complex by a large railway compound which had to be resited to make room for the work.

Planning and design criteria follow- ed similar procedures to those describ- ed in Part I of this article. The scheme adopted provides for an uninterrupted flow of traffic to and from the tunnel by a combination of elevated struc- tures and roads at ground level. A number of subways is provided to serve pedestrians (Fig. 1).

The capacity of the road connec- tions is greater than that of the tunnel, but is necessary in order to allow for future development in the area around the tunnel toll plaza.

Initially it was intended to let out the whole scheme for road connec- tions on the Kowloon side in one contract. However, indecision on the tunnel in 1968 and the need for im- mediate improvement at the junction of Chatham Road/Gascoigne Road/ Princess Margaret Road resulted in the Chatham Road flyover contract being let in April 1968.

In the event the flyover came into operation in October 1969 before the remaining work was started, with the favourable result that the usual in- convenience to the public during con- struction was minimised.
