Maybe the region only provided part of the total project budget?
As another data point, a somewhat similar but larger project -- about 100km bike highway in an urbanised region -- in Germany is probably not going to happen due to costs of >110 million EUR. That's approximately 10x as expensive per km as the project in Copenhagen, if the $1.4 million is the total project budget after all.
$100k/mile seems more reasonable given typical suburban rd pricing (~$200k/mile). Hugely dependent on how much the right of way has to be refrigged first I guess.
