Thanks for the reply. The markers are over 1/2 mile from the highway. Two are within maybe 20 feet of each other, the third is maybe 150 feet away. Not near a road or anything else that would require a right of way today. I suspect that they pre-date Hwy 375. Possibly related to the old Hwy 25, but unfortunately there is very little information available on that. I was hoping to narrow down the time frame and agency for further research.
