Well this is the beauty of having an unmarked crossing here: this is a legitimate place to cross, and since it is unmarked, the person when they get here should choose the safest way for themselves and usually they would walk up the street a little, cross, and get back on the sidewalk, and yes it may involve a little grass traversal.

There appears to be a curb lowering there, despite dumping people so close to memorial avenue, but it implies that people have the option of crossing there.  Else there would be no concrete connecting the path to the road on the southwest corner of that intersection.
