But I wasn't suggesting at grade through downtown that would require "fixing" in the future - I was suggesting above grade. Like I said it's an unpopular opinion but I like above grade trains. They don't seem to be a major issue in other cities around the world. Sometimes they even lead to unique building opportunities like the markets in Tokyo. And a light rail transit train beside a few office buildings is hardly as imposing as some of the elevated lines through residential areas in cities like Chicago or New York.
At $500 million cheaper you could afford to build more of the north line immediately as a result.
Anyway, the tunnels already been decided on so it's water under (over?) the bridge.
