It looks like a Union Bay expansion routing for 520 will make the final cut, perhaps this year.
The big benefit of this is that no additional lanes are needed to be built through the Montlake or Roanoke neighborhoods - not to mention reducing backups at the Montlake Cut and improved access to the UW and all of NE Seattle.
This letter concerns my first time suggesting this - correspondence from former Seattle Councilmember Jim Street from our first meeting. (Hard to believe I was once a member of the fighting 43rd - I may even have a friend or two left - in '88 I was a Dukakis Delegate.)
The letter also concerns a discussion of routing for Sound Transit, not my first mention of the UW routing/generational service planning idea. It does mark the start of a very productive discussion on the subject, not to mention a great working relationship.
(personal note, Jim's son also attended Hampshire, but only for one year - coincidentally the last for both of us.)
