Link Light Rail if WA had one billion trillion dollars (OC)

A couple days ago I posted my first version of a further-upgraded system map for the Link Light Rail. I got a lot of good feedback and I wanted to make a new map that would much better serve the Puget Sound Area, and ESPECIALLY Seattle.

I know most of this is not realistic, I just wanted to make something nice looking. They are never going to build a third bridge over the Narrows, they probably wont build a third tunnel for Fremont, etc. I just think trains are cool
