The Marina Coastal Expressway - the fisrt undersea Expressway at Marin
The Marina Coastal Expressway (MCE) - Singapore's first undersea road, costliest expressway and one with the widest tunnels - will open on Dec 29, four years after the $4.3 billion project started.
The 5km expressway, at $860 million per kilometre, has a 420m section that goes under the sea-bed just south of the Marina Barrage. There are five lanes in each direction. Linking the Kallang-Paya Lebar Expressway to the Ayer Rajah Expressway (AYE), it will allow swift east-west travel. Drivers currently using the East Coast Parkway (ECP) to join up with the AYE can switch to the MCE from Dec 29. The ECP will be downgraded to an arterial road that serves the Marina downtown.
