@stu – story says between ARB and HPB. There isn’t a sidewalk there in either direction. Shoulders through there in either direction are virtually nonexistent. If person was headed west – towards HPB, that ramp does not connect to sidewalk (sidewalk is only on down-river side of the bridge).
Unfortunately I have seen a fair amount of people walking in this area – and even people walking up that ramp and one guy walking along the up-river side bridge deck.
Obviously I hope the person is ok, but the particulars of this area makes me feel a bit surprised this doesn’t happen more often, unfortunately.
