other cities across the U.S. (like Boston) … regularly build subway lines for less than $360 million per kilometer
Huh? Boston hasn’t built a subway line in decades, let alone regularly builds them.
It did recently finish a light rail extension in an existing right of way, expanding a trench with retaining walls, but (a) that’s naturally much cheaper than digging a subway and (b) it took 12y longer than planned.
