for those who are not familiar with this, there is a deal in the works for King county and the port of Seattle to swap a 46 mile rail corridor for Boeing field. King county would take possession of the 46 mile rail corridor and turn it into a multi use park trail.
story is here
Anyway, after looking at a map this afternoon of the rail corridor, I was observing how it runs parallel to I-405. My thought was instead of turning it into a bike trail, how about leave the rails right where they are and improve the transportation infrastructure of the county and use it as a light rail line. The tracks are in place connecting Renton, Factoria, Bellevue, Kirkland, and Woodinville. It would be ideal in my opinion.
