EVOLUTION OF BRIDGE, FLYOVER AND VIADUCT CONSTRUCTION METHODOLOGIES IN URBANISED SINGAPORE

Over the years, road infrastructure development in Singapore has seen rapid growth and changes to meet ever-increasing demand and higher expectations of road users. In order too manage such demands and expectations in urbanized and land scarce Singapore, the Land Transport Authority of Singapore (LTA) is faced with a daunting task of enhancing the road network with minimum land take. With these constraints, the LTA is mindful in keeping upgrading projects within the existing traffic corridor such as the conversion of existing at-grade junctions into 2 to 4-tier interchanges, construction of elevated roads and viaducts above existing carriageways and construction of underground tunnel expressways. This paper looks into the evolution of construction methodologies for road development projects in Singapore. The pioneering road projects in the use of segmental concrete construction are also highlighted. This paper discusses the LTA's experience in facing the challenges that accompany the construction of bridges, flyovers and viaducts in a heavily built-up environment.
