Hey J,

Weird that that one segment is secondary. I agree it should be changed. I think the bike lane on Union Sq E should be one-way south of 15th St.  So I would extend way 923091012 north to node 4597668035. If you look in the intersection, there are west-bound bike lanes on both the north and south side, and they are both correctly mapped as part of E 15th St (way 481403100) There is no north-bound bike lane south of the west-bound bike lane on the south side of 15th St. 

Let me know if that makes sense to you. 

Thanks! Brandon
