List of world's most expensive transport infrastructure


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.

The size and scope of projects varies considerably; some projects are made up of a package of different infrastructure projects, while others may be single part of a larger network.

In order to limit the size and scope of this list, recent infrastructure that cost less than $1 billion is not listed; this is a common definition of a megaproject. However, historically significant projects may be listed. See also list of megaprojects.
