Sidewalk breaks

I was on South Elliott today and needed to cross the street from where Phydeaux now has its new store - and Mina's - to the other side where one finds Great Harvest, the snappy new ABC store, and soon, 3 Cups, among others.

It's a good example of how far down the list pedestrian walker interests find themselves. There is no reasonable crosswalk, and there ought to be many.

What has to happen for this to be implemented?
