Here's an older video I came across on http://www.streetfilms.org/. Watching it and seeing what New York has done on ninth avenue to accomodate cyclists gives me some hope for what other cities can do if they make it a priority. Looks like it's time for me to download and read the bicycling master plan for Seattle. I would love to see how many similar items will be incorporated. I know that there are areas that grade separated routes for bikes are in the plans (the 520 corridor, Alaskan Way).
Anyway, here's the video...enjoy.
