Yes, quite concerning. I came across it as I am a member of the Friends of the Parkway. All should submit comments on this as well as forward to others to ensure further thought is put into it---as we have seen of late in DC----so much stuff like this can slide through due to inaction.
Best road in US to ride a bike on IMO and through the draft mgmt plan they are implying that somehow maintaining the Parkway is easier and potentially cheaper when it is cars only? Makes no sense, esp since bikes are eco friendly, less traumatic for pavement---i.e. less maintenance and cyclists still bring economic benefits to Parkway communities-----Lets think Assault on Mt Mitchell, Fletcher Flyer, Hurt Pain and Agony, and Bridge to Bridge, among others---aside form all the individuals and groups that ride on their own.
Thanks for bringing this into focus. Let's hope it only becomes a faded memory that never comes to fruition.
