Drove the new bike lane on 40th Ave NW this morning. They have only done two blocks of 40th ave (essentially connecting the existing bike lanes on 37th St NW eastward, but there is a longer term proposal to connect from Brentwood west past Market Mall and all the way to the bike lanes on 53rd St NW.
It's not great pavement, but the extra space for cyclists is appreciated. There is a very interesting treatment heading west-bound at the four-way stop on 37th St NW: cyclists turning left (south) to take the bike lanes on 37th are directed to a cycling-only left-turn lane between the left-turn and straight-through travel lanes for motor vehicles. I am not sure if it was necessary or not, but I guess it mitigates having to make TWO lane changes now that bikes have their own travel lane against the curb. I guess it is good that it directs cyclists to make a left turn from an apporpriate position on the road, rather than from the right curb like some think they should do. But you still have to make a lane change across traffic to get there, so I am not sure how well received it will be.
