I'd love to embrace "Millennialism" and be car-free, but the inconsistency in transit options in parts of North Arlington is difficult-- there is minimal bus service and a lack of bikeshare stations, even near Marymount University. Adding bikeshare locations along the northern portion of Glebe Road from Lee Highway up to Chain Bridge would be helpful in continuing to connect this area with other parts of the County!
Washington Boulevard (especially north of route 50) would be an ideal corridor for a dedicated bike lane.
Also, what happened to the plan to extend the bike path beside Washington boulevard south of rt. 50? I thought that they were going to connect Columbia Pike to Crystal City and the Pentagon City Mall? I heard a lot about it three years ago but it has felt like deafening silence since then...
Driving westbound down route 50, I'm surprised that the bike path doesn't really continue past past Glebe Rd. Route 50 is wide enough to have a bike path that could be longer, perhaps even on both sides of the road.
