Deletion of List of world's most expensive transport infrastructure

Comment: There's plenty of coverage out there about such large projects - see https://books.google.co.uk/books?id=iH0tAgAAQBAJ&pg=PA333 International Handbook on Mega-Projects, for example.  We also have a more general list of megaprojects and it seems quite reasonable to have a sublist for transport projects such as Crossrail.  The main issue I'm seeing is that the costs should be normalised to adjust for inflation.  Such improvements, renaming, scoping, &c are best done by ordinary editing per our |policy.  Deletion is not appropriate because it would be |disruptive

Comment: since this list is just an |indiscriminate pieces of information. While well sourced, a simple list of expensive transit projects, as mentioned by the nominator, is a piece of original research. There's also no clear criteria to which the info can be sorted into, as everything from highways to subway systems. And it's a bit of a duplicate/merging of other lists that we have, as there is a List of roads and highways, List of metro systems, and List of bridges. Although none of them have any costs near the side, a simple note near the side could be placed near the name of bridge/subway/etc. if necessary. But having a standalone list of the costliest is original research, and, as the nominator pointed out, simply rivia|trivia. '''Aerospeed
