The Ruin at the End of Bridge Street

I'm sure there's an explanation for this, but I don't know why there used to be a bridge here, what it connected to on the far side, or why it's been abandoned.

Bridge Street's little more than an alley on the edge of Bailey Park, which is itself on the fringe of Battle Creek. The street runs between the outfield walls of three baseball diamonds and an ever-dwindling set of small houses.
