It is really amazing that roads can be built so deep underground. With the Kallang Paya-Lebar Expressway (KPE) built across a river underwater, now the Marina Coastal Expressway (MCE) too is built literally, under water. The tunnel will pass under the Singapore River, near the Marina Barrage. This new five-lane expressway will be the tenth expressway in Singapore, providing a link to the Kallang-Paya Lebar Expressway (KPE), the East Coast Parkway (ECP) and the Ayer Rajah Expressway (AYE). This is to cater to the likely increase in traffic volume around the Marina Bay area, especially with the opening of the Marina Bay Sands Integrated Resort and the upcoming Marina Bay Financial Centre.
Stretching 3.6 km from end to end, the MCE runs through reclaimed land. It also consists of more than 0.4 km of tunnel running directly under the seabed of Marina Bay. The MCE is scheduled to be completed by the end of 2013, not long after the opening of the Integrated Resort. These developments in architectural techniques have allowed Singapore to make full use of her limited land space.
