Abstract

Well-organized delivery of urban services and an efficient transportation system can be considered the keystones on which the success of a metropolitan area primarily depends. An appropriate and adequate transport system is a main requirement for the sustainable economic and social development of cities. The Rajagiriya flyover has direct and indirect beneficial impacts on the economy of Colombo, which is in the main district of Sri Lanka. But the construction of these kinds of structures is close to populated town areas, and they are surrounded by a natural environment. And also, they will have some unfortunate impacts on the social, physical, and ecological environments. The main objective of this study was to identify the social and economic impact of the Rajagiriya flyover construction. Hence, to achieve the target, 50 commuters, 50 traders, both permanent and mobile, surrounding the flyover, and 50 householders were selected through the purposive sampling method. Focus-group discussion and questionnaire surveying techniques were used to collect primary data from around the Rajagiriya junction, while other secondary data sources such as traffic and land use data were also collected. The study found heavy congestion along the Sri Jayawardenapura Mawatha between 07:30 h and 09:00 h in the morning and 16:30 h and 19:45 h in the evening, with the majority of the sample being daily commuters. During the construction period, fuel consumption was higher than before. People encountered two major issues: fuel waste and having to stay in the flyover for an extended period of time. Before the flyover construction, 85% of the customers visited their shops. But after the construction, the number of customers was as low as 25%, the traders said. Finally, the researcher found that the number of vehicles is higher than before the construction. As a result, traffic congestion has increased even more than before. Moreover, this study demonstrated that the construction of the flyover project was a failure due to an insufficient feasibility study.
