Marina Coastal Expressway, Singapore
View images
Construction is proving to be challenging as part of the expressway tunnel runs under the seabed from Marina Barrage, which at times needs to be opened to allow water to flow out
To bridge the southern end of the Kallang-Paya Lebar Expressway
with the East Coast Parkway to the eastern end of Ayer Rajah
superhighway, the new dual, five-lane Marina Coastal Expressway
will be crucial in cutting congestion on completion in 2013.
The 5km expressway will provide scenic views of Singapore’s straits, linking the proposed Marina Cruise Centre and other marina developments to the rest of the island microstate.
Mott MacDonald has been appointed as design consultant for three of the six design and build contracts. We will provide ground-breaking engineering services for 3km of roads, including 2km of twin-cell box tunnel, two ventilation buildings and slip roads.
Around 3.6km of the Marina Coastal Expressway's (MCE) total route length will be based in an underground tunnel, with two ventilation buildings and 13.3ha of land reclamation. The expressway will continue from the southern end of the Kallang-Paya Lebar Expressway and traverse the Marina East area in a southerly direction adjacent to the Marina Bay golf course, before crossing the Marina Bay Channel south of the Marina Barrage.
Continuing through the Marina South coastal area the MCE will have a diamond interchange to and from Marina Boulevard and Central Boulevard. It will then head west to meet the Ayer Rajah Expressway viaduct.
Key aspects of our role encompass the design, construction and completion of:

Key aspects of our role encompass the design, construction and completion of:
- 800m of twin cell box vehicular tunnel structure and slip tunnel connection stubs for future entrance/exit ramps
- 950m of twin-cell box vehicular tunnel structure, slip tunnels and at grade roads connecting to Marina Boulevard and one ventilation building and trunk link sewers with associated manholes
- 330-390m (west-east) of depressed road structure plus 670-610m (west-east) of vehicular tunnel structure
- A tunnel stub for future realignment of the MCE in addition to slip tunnel connections to the central boulevard
