Very interesting. I'm trying to figure out what purpose the entire setup served. As cpzilliacus suggested, from both the satellite image and street view on FM 1734, the small industrial site looks dormant. As to the haulage roads, all of the spurs appear to peter out in meadows very close to the small lakes that dot the area. Yet it's odd to me that the roads fade away–rather than terminating solidly at a definite loading/unloading point, stockpile site, etc. Whether something was being collected and taken back to the industrial site or vice versa, I haven't the slightest idea what was going on here. If anyone has a solid idea, I'd be very interested to know.
I'm wondering if once mining operations are over if this will became a public county road.
I would doubt it because, other than shaving a few miles off the US 67 to US 271 trip (which admittedly
is worth something), I don't see that the route has enough value to offset all of the costs of putting it in service.
