Megaprojects have been constructed since ancient times, but also intensively developing today, especially in the infrastructure sector. In this article, megaprojects are presented historically, etymologically, case studies explored and literature reviewed to identify characteristics and main shortcomings of the phenomenon. A distinction is made between the old and the new forms of megaprojects, their impacts, and also risks defined. In contrast with the popular contested megaprojects of the 1960-1980s, highly influenced by the modernist schemes, the contemporary ones seem a much sensitive reinterpretation considering the environmental problems and with a much stronger concern for the challenges of the "urban age": sustainable development, renewable energy, etc. The overall research goal is to contribute to the more general, theoretical contention on the new emerging megaprojects. A statistical exploration of 150 megaprojects constructed, but also under construction (with a start date after the year 1990), comprising of infrastructure megaprojects solely like: roadways, railways, airports, metro lines, seaports, rapid transit, bridges, tunnels, and hybrid ones that encompass the construction of new transportation means together with urban development, is done with the scope of enlarging the findings in the literature review and test their accurateness from a performance and governance perspective. It is found that the new wave is still as flawed as its predecessor, underestimated costs and delays are still frequent regardless of their geography, program, or even size and due to conflictual planning processes, misinformation, and lack of transparency considering the governance dynamics, the political inequality in access to decision-making processes, there is an unequal distribution of risks, burdens, and benefits from projects.
