I am really excited to see this positive step being implemented here in Portland. I hope it spurs even more bike infrastructure and more folks out of their cars and on 2 wheels!
Please make this a success by converting car parking space into separated bike lanes designed to accommodate right hand turning with out leaving the bike lane and dedicated bike traffic signals. Also, It may be an advisable step to install more "Yield to bikes" signage at any intersection where autos may need to turn right across a bike lane. Since it seems to be a impossible concept for most to grasp unless a sign is there to remind them...< sorry for the rant>

Great idea!!!
