Why is the State Government building more highways when we are supposed to be advocating Public Transportation Vs Private vehicles?
It is common knowledge that that car ownership increase in Penang is inevitable with the fast-growing young population increasing affluence.
As the State Government is targeting to achieve a 40:60 (public: private) mode share, road transport infrastructure is still required to cater for the 60% Private transportation.
Why can’t the State Government increase the quantity of public buses and the operational efficiency instead of building more highways?
Increasing bus quantity without freeing up the roads will not increase the operational efficiency.
Existing and future growth of private vehicles need to be dispersed first to other road networks which have been strategically planned out.
Ultimately, the target is to achieve a 40:60 mode share for Public and Private transportation via other efforts under the PTMP such as public transport strategy and institutional strategy.
What are the benefits of PIL 1 to the public?
At present, Penang is served with only one Spine road which is the Tun Dr. Lim Chong Eu (LCE) Expressway which is experiencing congestion during peak hours.
PIL1 is meant to serve as a Second Spine to the congested LCE Expressway. PIL1 will be a new bypass functioning as a Traffic Dispersal System with five (5) strategic Interchanges connecting Gurney Expressway, Jalan Paya Terubong, Jalan Tun Dr Awang, LCE and first and second bridge.
In sum, PIL1 is mean as an alternative to LCE Expressway. PIL1 will ultimately disperse traffic from the LCE Expressway allowing for better traffic flow for both private and public transports.
The Tun Dr Lim Chong Eu (LCE) Expressway was already congested not long after it was constructed. Will PIL 1 be facing the similar situation? How long can the PIL 1 sustain traffic flow without being congested?
The LCE Expressway is not a highway with controlled access. There are numerous entry/exit points along the alignment as this is the only Spine road connecting the island from North to South.
Being underground & elevated, PIL1 will be access controlled to cater for future traffic growth.
What kind of tunnelling method will be used for PIL1?
The drill and controlled blast method will be used. This method is the most common method used for tunnelling in granite that has been adopted in Malaysia since the 1970s; including for the Genting Sempah Tunnel (Karak Expressway) and Menora Tunnel (North South Expressway). The drill and controlled blast method is a safe and established method that takes into consideration all aspects related to ground movement and settlement.
What kind of safety measures for blasting works where it is adjacent to residential area?
Both DOE and JMG have set guidelines on the allowable vibration at sensitive areas such as residential due to controlled blasting works. The blast design will be developed in line with the allowable limits and trial blasts will be carried out to before actual works begin to ensure the works are in full compliance to relevant guidelines.
Part of the PIL1 alignment to be construct along the river reserve. What is the method and measure to protect the existing river during construction and post construction?
In line with DOE guidelines, the Land Disturbance Polution Prevention & Mitigation Measures (LDP2M2) plan will be developed during detailed design stage for approval by DOE. In this plan, details of mitigation measures such as check dams, silt traps, silt fences, sand bag perimeter bunds etc will be designed to ensure the existing rivers are not polluted.
Besides this, the Environmental Management Plan (EMP) will also be submitted to DOE prior to construction. The EMP entails the types of tests as well as the frequency of test to be carried out during the construction period. All test reports will need to be submitted to DOE periodically.
What are the safety measures to be complied to storage the explosive and transporting to site?
Any storage of explosive material will be subjected to approval by Polis Diraja Malaysia (PDRM) in compliance to stringent requirements with regards to safety and suitability of the proposed locations. Basic requirements include minimum distance of 500m from any residential houses & armed guard security.
Explosive material will be transported in small quantity to site daily and any unused material for the day must be returned to the bunker.
What is the solution taken to preserve historical locations such as Bukit Bendera and Kek Lok Si temple?
In line with the Penang Hill Special area Plan, the PIL 1 highway is designed to be fully tunnel within the SAP boundary. This ensures the beauty and serenity of Penang Hill is preserved.
As for Kek Lok Si temple, the alignment is approx. 500m away from the temple. Such a distance means the temple is unaffected by the presence of PIL 1.
Any bore holes done till date (soil and rock testing)?
Yes. Bore hole have been conducted. However, more will need to be carried out during detail design stage to gather more info to ensure safe and efficient design of PIL 1
If the tunnel drilling through the Air Itam Hill, will it damaging the Air Itam Dam and Kek Lok Si temple?
The tunnel alignment is approx. 500m from both Air Itam Dam and Kek Lok Si temple. The drilling and controlled blasting has negligible impact in terms of vibration and settlement to structures or buildings at such distance. Air Itam Dam and Kek Lok Si are both safe.
Does the Traffic Management Plan consider the safety requirement of Disabled User?
The Detailed Traffic Management Plan which will be developed prior to construction for Local Authority approval will take into account the needs of relevant stakeholders including the disabled. Safety and security of all public is of the utmost priority.
How effective is the Traffic Management to alleviate the traffic during construction?
While public may experience certain degree of inconvenience during the construction period, this is short term pain for long term gain. All the necessary measures such as maintaining the number of lanes, comprehensive traffic signages and early notification will be done to minimise the inconvenience of road users during construction. Limited work will be carried out during peak hours such as 7am to 9am and 5pm to 7pm.
Construction of tunnel will transfer out plenty tonnages of rock from the tunnel site by the large lorries. How is the road safety emphasis to the narrow road user and motorist?
The tunnel mucking will be transferred out via carefully selected routes to ensure the minimum inconvenience to road users. Transportation times will be coordinated so as not to clash with peak hours.
All lorries will be inspected to ensure they are road worthy and safety precautions such as closing the load with tarpaulin canvas are adhered to at all times.
