Sand Hill Rd at Evering Rd. It looks like the truss bridge is crossing Fink Run which joins the west branch of the Huron River. The moble home has been replaced by a house.

I believe this is actually everingin and boehler rd

You're right. I remember going over and over the 1972 high altitude aerials trying to match this location. The two intersections are very similar. I moved the red pin on the map to the correct intersection. It's a lot further from the flight path.
