There is a book though unpublished that I have a copy of that might help........It is..........

MILITARY ROAD by H.L.Rumage, O.C.Davidson, C. Plishke and J.L.Buchanan - Research field Workers
WORKS PROGRESS ADMININSTRATION (WPA)
Indian Pioneer History Project for Oklahoma
1937-1938

It tells step by step information along the military roads telling what houses and structures that are passed along the roads and how many feet off the road they were. Even has grids of sections showing the roads going through it with some of the features of road marked. Very detailed and I think Grant Foreman had a part in it also. The last part of the report is about Ft. Gibson.

I think the Okla. Historical Society has this report in their collection.
