In one of the street view images (the one facing along the direction of traffic, from a spot far enough upstream that you can see the elevated walkway in the upper left corner of the image), there is a parking garage sign with one arrow pointing along the direction of traffic (which apparently is for one of the entrances in task #198)  and a second pointing along this feature labeled as an "alley". This could be an entrance to a parking garage in the unlabeled building next to the First Citizens Bank Plaza, rather than an alley.
