10 ON10.1 Introduction10.1.1 This concluding chapter summarises the recommended transport strategy, includingproposals for the the construction of new highways and railways and proposals fortransport management policies. The chapter also discusses the steps necessary forimplementation of the recommended strategy and other issues concerned withlong-term transport planning. The recommendations and conclusions, unlessotherwise stated, relate to the airport retained at its present site.10.2 Recommended Highway Programme10.2.1 The Study evaluated a large number of highway projects and established prioritiesfor highway construction in the 1990s. in preparing this new programme of highwayprojects, the Study took into account the programme of highway projects alreadyunder construction or in the final stage of design.10.2.2 The total value of all public and private highway related investments currently underconstruction or firmly committed is estimated at nearly $23 biliion (in 1988 prices),of which $10-11 billion remained to be spent from the beginning of 1989. Underpresent budgetary considerations, funds for new projects recommended by thisStudy, and discussed below, are not expected to become available until 1992 at theearliest.10.2.3 It is also noted that the construction industry is experiencing severe cost inflation atthe present time; highway costs rose by over 30% and railway costs by 40% to 50%from mid-1986 to mid-1988. It is possible therefore that funding limits and capacityconstraints could extend the construction period for committed projects, thuspostponing the start on projects recommended by the Study until 1993.Recommended Highway Projects10.2.4 The CTS-2 Study recommends a $20 biliion (in 1988 prices) construction programmefor new highway projects for construction in the 1990s. The programme issummarised in Table 6.4 and the locations of the major projects are shown inFigure 6.3 of Chapter 6.10.2.5 The recommended highway strategy includes the construction of three new trunkhighways:(1) Route 3 from Hong Kong Island to Yuen Long, via the Western HarbourCrossing and northwards on new reclamation along the west side of theKowloon peninsula, through Tsing Yi Island and then through the Tai LamCountry Park, mostly in tunnel.(2) Route 7 on Hong Kong Island, extending from the current end of the IslandEastern Corridor in Causeway Bay through the planned Central and WanchaiReclamation to Western and round the coast to Aberdeen.(3) A new route which extends the Hung Horn Bypass from Tsim Sha Tsui, alongthe east side of the Kowloon peninsula, across the Hung Horn Bay reclamationand under the airport in a second airport tunnel to an interchange with theKwun Tong Bypass now under construction.10.2.6 The major trunk road projects would be built in stages; the following priorities arerecommended:(1) The highest priority is for Route 3 (Western Harbour Crossing). It is currentlyplanned as a 6-Iane immersed tube tunnel connecting Western District on HongKong Island with the west side of the Kowloon peninsula. It would require194
