An efficient mega-structure is both a prerequisite and a vital component of development. A few
initiatives generate a positive rate of return, but all should have positive non-economic effects and
contribute to societal benefits. The social influence of decisions or activities that lead to
development is considered as a result or effect. It can also be seen as a societal result of progress.
The fundamental problem with social costs and benefits is that they are difficult to anticipate and
quantify and are viewed differently by authorities, decision makers, and project developers. This
research aims to investigate Femern Belt Fixed Link efforts related to social mobility in Rodby
and Rodbyhavn to improve the community. A semi-structured interview using a qualitative
inductive method is used to acquire data. Interviews were conducted both in person and through
digital platforms. According to the findings, the Femern Belt Fixed Link is portrayed as a highly
creative and long-term link connecting Scandinavia to the rest of Central Europe. Many positive
changes are projected in surrounding regions. Residents are optimistic that the infrastructure would
spur development in the town through mobility, tourism, commercial and economic activities,
employment opportunities, and so on despite the possible downsides of such chances.
