No sidewalk + sidewalk to nowhere

There is no walkway from the main sidewalk to the post office.  If you are on foot, you have to navigate your way through the parking lot or walk along the driveway hugging the curb next to Dominos.   

And even though the post office is right across the street from Safeway it's not an easy walk.  Ever notice how the sidewalk along the storefronts in the Safeway shopping center comes to an abrupt end before it connects with the main sidewalk on 14th?  It's a sidewalk to nowhere.  Clearly people want it to connect.  See the path they've worn? Why was it built this way?  Maybe it has something to do with the slope?  In any case, this really bugs me.
