List of transport megaprojects

This is a list of transport megaprojects. 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.

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries.

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]
