Oh I agree! I didn't spell it out in the article (I am the author), but I am a huge advocate of walkability. But if you gave me $1M and asked me to make this area more walkable, I still wouldn't build a bridge there. It's just so terribly unwalkable that that project would not even make my list. I would start with some sidewalks to get folks off the roads.
Funny story: the original residents of Richfield push back against building sidewalks, because they thought NOT having sidewalks would make them more distinguishable from Minneapolis as a suburb. That is bonkers to me.
