6. OF6.1 Introduction6.1.1 This chapter reports on the evaluation of highway projects and the development of ahighway investment programme. The evaluations, combining traffic and economicfactors, were made in the context of the demographic changes, economic growthand major new developments reported in previous chapters. They also took intoaccount presently known and committed changes in the transport network.6.1.2 It was assumed in the analyses that the airport would remain at its present site at KaiTak until 2001. During the course of the Study, the possibility emerged for theairport to be relocated towards the end or by the turn of the century. The impact ofairport relocation on the highway investment programme is included here whereappropriate, and reported in more detail in Chapter 10.6.2 Committed Highway Projects6.2.1 At the present time, many highway projects are under construction, or have beencommitted to start in the near future. Estimates of transport conditions with theseprojects completed served as the reference against which the need for furtherhighway projects was evaluated6.2.2 Committed highway projects were identified chiefly from the Public Works Programme,updated to the end of 1988. The major committed projects considered byCTS-2 are listed in Table 6.1 and illustrated in Figure 6.1.6.2.3 Several trunk highways are currently under construction which are expected to havea significant impact on the Territory's travel patterns. The most important one is anew trunk road linking the east end of Hong Kong Island with the New Territories atSha Tin via the Eastern Harbour Crossing, the Kwun Tong Bypass and the Tate'sCairn tunnel. The Eastern Harbour Crossing is due to open in 1989, and the otherparts of the route two years later in 1991. This route will bring traffic relief to the twomain existing traffic bottlenecks in the Territory; the Cross-Harbour tunnel and theLion Rock tunnel.Table 6.1COMMITTED HIGHWAY PROJECTSProject DescriptionReferenceNo. inFig. 6.1(A) Hong Kong IslandRt 1—Route Through Aberdeen—Stage 3 1Rt 7—Upgrading and Dualling of Connaught Rd, Stage 1 & 2 2Rt 8—I EC, Stage 3, Shau Kei Wan to Chai Wan 3Rt 8—Reconstruction of Causeway Bay Flyover 4(B) KowloonRt 1 — Princess Margaret Road Flyover Improvement 5Rt 1—ELE.
