How could the proposed undersea tunnels linking mainland Singapore to Pulau Tekong be built?
Singapore is studying the feasibility of building the tunnels.
The Marina Coastal Expressway (MCE) in Singapore, completed in 2013, was the first highway to include a segment under the sea. Now, the government is exploring the feasibility of constructing undersea tunnels to connect mainland Singapore with Pulau Tekong, the largest outlying island. Engineers clarified that the planned tunnels will likely differ from the MCE's undersea portion, and discussed the key factors to consider before approving the project.
