Malaysia’s Transport Minister, Seri Kong Cho Ha, has asked the Penang state government to review the project for building an undersea tunnel at Penang port to ensure that the facility’s depth does not impede the port’s development. According to the minister, the tunnel’s depth should be at least 18 metres to enable the port to process ships accommodating up to 18,000 containers. The undersea tunnel project involves the construction of a 6.5 km tunnel between the Gurney Drive seafront line and Bagan Ajam. Earlier, concerns were raised about the proposed depth of 14 metres for the tunnel. The port authorities have stated that the depth must be between 17 and 18 metres to accommodate larger ships.
