This account of a recent bus commute drew a lot of feedback. Two emails came from Rep. Judy Clibborn, the chair of the state House Transportation Committee.
She explained that she's arranging to ride through the 520 corridor with the Department of Transportation to see what can be changed. Yet there will be opposition to any tinkering with the status quo:
I agree that we have some issues and will be working to get some of that merger smoothed out before we reach the new bridge and later implementation of tolls etc. I am interested in what comes out of the Urban Partnership regarding some of what you mentioned but I am also aware of the political reality of what we can do without support from the citizens. It will take a lot of education.
For info on the partnership, see the link for the Puget Sound Regional Council.
