I'm not arguing the change.  I would point out that the bike lane now masks what functioned as basically an entrance / exit lane on the highway.  The abutting entrances were not an issue to maintaining highway speed on the road.  They do not now with the bike lane.  The bike lane is basically treated the same way without apparent risk to the bikes as I have never seen one in it.  That is a comment on what I think of the wisdom of overlaying a bike lane there for how the lane has functioned.

Northwestern Highway / M-10 is similar in nature and use to nearby Telegraph Road / US-24 which has been tagged as Primary since at least 2009.

Thank you,

Doug Peterson
