Dick:
You beat me to the punch!
To get truly Sherlock Holmesy here, I do think the photo may be aligned correctly -- north is top, east is right, and so on -- because of the nearby ballfields. Almost all ballfields -- and those look like pretty nice ones, with some thought and money put into them -- are aligned so that batters avoid looking to the west, especially, and to some extent the south (as this is a northern hemisphere course, and thus northern hemisphere ballfields, with the sun predominantly on the southern half of the sky -- do I have that right?). None face west, and two of the three avoid facing south.
Thus, I think that's an east-west running highway.
