Central Subway in San Francisco is $1.6 billion for 1.7 miles, or $1 billion a mile.
Second Avenue Subway in NYC is $17 billion for 8.5 miles, or $2 billion a mile.

I doubt a project in Portland would reach the costs of tunneling in Manhattan, but the number of stations required would make it more costly than University Link. So I'm going to guess $1 billion a mile, for $3 billion total.

Much as I'd love to see this done, I think it's obvious why it hasn't happened already.
That is a lot of money for a 3 mile subway line, I would rather see Portland build two new lines for $1.5 billion each, than to have a subway line through downtown. And of course the amount of streetcar lines $3 billion could buy would also be amazing.
