Will Penang opt for a bridge or tunnel alternative?

Question

Accepted Answer

Penang's Infrastructure Decision: Bridge or Tunnel Alternative

Consortium Zenith Construction Sdn Bhd (CZC) is finalising feasibility studies for the undersea tunnel component of the RM6.3 billion project, with a 96% completion rate expected to be submitted to the state by September or October. Alongside the tunnel proposal, CZC has also put forth a bridge as an alternative option for the state government to consider. The final decision on whether to proceed with the undersea tunnel or the proposed bridge will rest with the state authorities.
Bridge as a Viable Alternative

CZC has formally presented a bridge as an alternative to the planned undersea tunnel. This proposal is being offered for the state to evaluate, allowing for a comparison of the advantages and disadvantages of both infrastructure options. The inclusion of the bridge as an option is intended to provide the state with a broader set of choices for the connectivity project.
Potential Advantages of a Bridge

A bridge infrastructure presents specific engineering and functional benefits that CZC has highlighted. Notably, the design of a bridge could be adapted to accommodate a light rail transit line running beneath it, offering multi-modal transport integration. Furthermore, considerations for bridge height would be made to ensure passage for larger maritime vessels through the channel.
Undersea Tunnel Feasibility Studies Nearing Completion

The undersea tunnel, initially planned to span approximately 7 kilometers and facilitate a travel time of around eight to nine minutes between Gurney Drive on the island and Bagan Ajam on the mainland, is nearing the completion of its feasibility studies. These studies are at 96% completion and are slated for submission to the state by September or October. However, CZC has acknowledged that the studies and detailed design for the tunnel have experienced delays over the past two years, attributed to "intense pressure" and surrounding controversy. The submission of a detailed environmental impact assessment (DEIA) report for the tunnel is also noted as a challenging but necessary step.
Toll Concession and Traffic Considerations

Discussions are ongoing regarding the potential for a toll-free undersea tunnel, a prospect that raises questions about the impact on the existing tolling structures of the first and second bridges. The second bridge, connecting Bayan Lepas on the island to Batu Kawan on the mainland, has reportedly experienced lower-than-expected traffic volumes, with a suggestion that its alignment could have been more beneficial if it connected to the northern side of the mainland, an area with higher traffic flow from regions like Kulim, Sungai Petani, and Southern Thailand. The undersea tunnel is intended to alleviate congestion on the first bridge.
