Singapore is exploring the feasibility of constructing large-scale undersea tunnels connecting Pulau Tekong to the mainland. Prime Minister Lawrence Wong revealed that this project would represent a first for the nation in terms of underground road tunnel construction due to its scale. The potential tunnels aim to improve connectivity to the island, which currently relies primarily on ferries. Further studies are underway to assess the technical and economic viability of the project. This development signals a significant investment in Singapore's infrastructure and future transportation network. The project, if realized, could significantly alter access to and development on Pulau Tekong.
