List of transport megaprojects
This is a list of megaprojects within the transport sector. Care should be taken in comparing the cost of projects from different times, even a few years apart due to inflation; comparing nominal costs without taking this into account can be highly misleading. Note that inflation-calculated values are current as of 2023[update].
According to the Oxford Handbook of Megaproject Management in 2017, "Megaprojects are large-scale, complex ventures that typically cost $1 billion or more, take many years to develop and build, involve multiple public and private stakeholders, are transformational, and impact millions of people".[1]
