THE PROPOSED PAN ISLAND LINK 1 HIGHWAY PROJECT, PENANG EXECUTIVE SUMMARY 1.0 INTRODUCTION The Penang State Government proposes to build a new highway that will connect the Gurney Drive area in the northern part of the island to Bayan Lepas in the south. It will form a second north-south spine road that will provide relief to the Tun Dr. Lim Chong Eu (LCE) Expressway. 1.1 Project Title This Environmental Impact Assessment study is prepared for the “Proposed Pan Island Link 1 (PIL 1) Highway, Penang”. Henceforth, it shall be referred to as the PIL1 Project. 1.2 PROJECT PROPONENT AND CONSULTANTS i. Project Proponent The proponent for the PIL1 Project is the Penang State Government.

Hence the PIL1 ES - 2 THE PROPOSED PAN ISLAND LINK 1 HIGHWAY PROJECT, PENANG Project falls under the Second Schedule of the Environmental Quality (Prescribed Activities) (Environmental Impact Assessment) Order, 2015. Therefore, an EIA report has been prepared for submission to the Department of Environment (DOE) Putrajaya for approval prior to the start of the project development. 1.4 CONFORMANCE WITH THE GOVERNMENT’S DEVELOPMENT PLANS The Penang State Government has carried out a comprehensive integrated study to improve the management of transportation in the State. Subsequently the Penang Transport Master Plan (PTMP) was produced in May 2011. Following some enhancements, the PTMP was adopted by the Penang State Exco on 16 Dec 2015. The PTMP has proposed the rationalization of new highways with existing ones to form a series of strategic National, State and District highways that would connect with the National highway network and to local destinations. The Pan Island Link 1 (PIL1) Highway is a new highway recommended in the enhanced PTMP. Thus it is in line with the State Government’s development plans. Among the key physical infrastructure initiatives in the 11MP period include concerted measures to enhance connectivity across transport modes and regions by implementing need-based transport infrastructure in the form of “Multimodal Transport Networks” to improve travel efficiency, increase productivity and enhance logistics. The proposed PIL1 Highway – a needs-based highway to improve road hierarchy in Penang Island and function as a crucial strategic bypass for traffic dispersal on Penang Island, is therefore in line with the 11MP objectives. 2.0 STATEMENT OF NEED Efficient road systems play a critical role in economic development by providing economic and social opportunities and benefits that results in positive multiplier effects such as better accessibility to markets, employment and additional investments. Unfortunately, many major roads and highways in Penang experience peak-period congestions. Based on the traffic volume forecasts summarized in the PTMP, the traffic congestion situation on the Island will worsen in the future if nothing is done. For example, the Tun Dr Lim Chong Eu Expressway (LCE) which is a key North-South road on Penang Island currently experience peak-period congestions and there are only limited opportunities to create more capacity on this expressway due to the surrounding developments. What is needed is a new well ES - 3 THE PROPOSED PAN ISLAND LINK 1 HIGHWAY PROJECT, PENANG designed bi-directional North-South highway that would improve local and regional traffic circulation on Penang Island. The proposed PIL 1 Highway will provide a second North–South spine road that will allow for better traffic dispersal and improve accessibility to various areas along the north-south corridor of Penang Island. It will be constructed as a dual 3–lane purpose built limited access highway that will ensure certainty in speed and significantly shorten north–south travel time to only 15 minutes from Gurney Drive to the Penang International Airport compared with the current time of 45 minutes. It would also provide relief to the currently congested north-south roads on eastern Penang Island other than LCE. Some other benefits of the proposed new highway are: It would be a strategic bypass segregating regional traffic from local traffic – for better traffic dispersal and also improve accessibility from North to South of the Island; Have six interchanges to connect the main hubs on the Island, the Penang Second Bridge, the Penang International Airport, Bayan Lepas, Relau, Air Itam, Tg Bungah and also lead to George Town; Be built beyond the developed area of the city, to disperse traffic rather than forcing it to converge in the extended city; and Enhance accessibility and open up opportunities for development on the west and south side of the island and help to decentralize growth from George Town. 3.0 PROJECT OPTION Alignment Option Three (3) alignment options were considered in the selection of the PIL 1 Highway alignment. All 3 alignments have common sections. Option 2 differs from Option 1 at the start section where starting from Gurney Drive, the alignment heads in a north-westerly direction and crosses Mount Erskine road and a cemetery to Youth whereas in Option 1, the alignment moves from Gurney Drive through Jalan Bagan Jermal and Jalan Gottlieb to Youth Park. Option 3 differs is similar to Option 1 ES - 4 THE PROPOSED PAN ISLAND LINK 1 HIGHWAY PROJECT, PENANG except at the Sg. Ara, where after exiting Tunnel 4, the alignment moves along a steep ravine near Regency Heights condominium and a temple before joining onto the alignment for Option 1. Option 1 was selected since it has lesser encumbrances and is relatively cheaper to construct compared to Option 2 and has lower environmental impacts when compared to Option 3. Elevated Structure vs At-Grade Option Constructing the proposed highway at grade along the proposed alignment will present numerous technical, social and environmental issues. Therefore, the elevated highway plus tunnelling option was selected when considering the same key factors. Tunneling Option Three tunneling methods were considered which are the Drill & Blast method, Cut and Cover method and the Tunnel Boring Machine (TBM) method. Based on geological, economic and sociological considerations, the Drill and Blast method was selected for use in tunneling in the PIL1 Project. No-Project Option The no project option will intensify traffic problem currently experienced on Panang island. An inefficient transportation system would not be able to facilitate orderly economic growth in the State. With the No-Project Option, traffic conditions will deteriorate further in years to come, causing distress to day-to-day life of road users, and eventually hamper economic growth of the State as existing investors may pull out and new investors will look for other more conducive environment to invest. 4.0 PROJECT DESCRIPTION The 19.5 km long PIL1 Highway is a dual 3-lane non-tolled highway and consists of viaduct sections (7.6 km), tunnel sections (10.1 km) and an embankment road section (1.8 km). Six interchanges (IC) have been proposed at key locations along the Highway viz. the LCE IC, Tun Awang IC, Relau IC, Paya Terubong IC, Utama IC and the Gurney IC (Figure 4.1) ES - 5 THE PROPOSED PAN ISLAND LINK 1 HIGHWAY PROJECT, PENANG The Project is expected to commence in Early 2018 after all regulatory approvals have been obtained. It is scheduled for completion in End 2023 / Early 2024 over a construction period of 60 months. ES - 6 THE PROPOSED PAN ISLAND LINK 1 HIGHWAY PROJECT, PENANG Figure 4.1. PIL 1 Highway - Overall Layout ES - 7 THE PROPOSED PAN ISLAND LINK 1 HIGHWAY PROJECT, PENANG 4.1 PROJECT COMPONENTS The typical viaduct will have a lane width of 3.5m with a central median of 1.6m and a shoulder width of 0.5 m. The standard span for the viaduct shall be around 30 - 40 m. At specific sensitive locations, longer deck spans (cable stayed bridge and box girders) will be adopted. The tunnel section will have three lanes for each direction. The “Drill and Blast” method will be used for the construction of the tunnels. A short embankment section will be constructed between the 3rd and 4th tunnels. 5.0 EXISTING ENVIRONMENT Topography The highest contour in the project site is 440 m and the lowest is 1 m above the Mean Sea Level (Table 5.1). About 61.7% of the area falls into Class 1 (0-15o) slope classification (mainly between Gurney Drive to Air Itam and between Sg.
