Marina Coastal Expressway
The Marina Coastal Expressway (Abbreviation: MCE) is the tenth of Singapore's network of expressways. Construction for the MCE began in 2008 and was completed at the end of 2013. The expressway was officially opened on 28 December that year by Senior Minister of State Josephine Teo in the presence of Emeritus Senior Minister Goh Chok Tong, and was opened for vehicular traffic the next day. Route The 5-kilometre (3.1-mile) MCE connects with the southern end of the KPE and its junction with the ECP to the eastern end of AYE. This links the eastern and western parts of Singapore to the New Downtown, currently being developed in the Marina Bay area. The MCE, with five lanes in each direction, handles the large number of commuters to be drawn to the offices, homes and recreational attractions there. It opens access to the Marina Bay Cruise Centre Singapore in Marina South and the existing Marina South Pier.

Feasibility studies were conducted for the new expressway, and then Transport Minister Raymond Lim later announced on 27 July 2007 that approval had been given for the construction of a new 5 km long Marina Coastal Expressway (MCE) at a cost of $2.5 billion. The expressway, which includes Singapore's first undersea tunnel, links the East Coast Parkway and Kallang-Paya Lebar Expressway to Marina South and Ayer Rajah Expressway and opened to traffic on 29 December 2013. The expressway comprises a tunnel, while the rest are at grade or depressed, with a view of the Singapore Strait. The tunnel includes a stretch that travels under the seabed, away from the Marina Barrage. This had posed particular engineering challenges in the tunnel construction as large amounts of water were let out from the barrage from time to time. At its deepest point, the expressway lies about under the seabed. The long MCE is Singapore's most expensive expressway. On 28 April 2009, the Land Transport Authority revealed that it has awarded about S$4.1 billion worth of contracts, much more than the initial estimate of $2.5 billion. The construction of the MCE also required undersea dredging. More than of land was reclaimed to build the MCE. In contrast, the KPE, which is and has portions running under canals and rivers, cost only $1.74 billion.
