List of transport megaprojects

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.

This is a list of megaprojects within the transport sector. Take care 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.

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]
