The Beale Wagon Road followed the Marcy Trail along the south side of the Canadian River from Indian Territory to New Mexico Territory. I have been able to find only one Texas Historical Marker, #17949, on the Beale Wagon Road and it was located in SW Borger, Texas at the corner of Marcy Trail and Gregg Drive near the Dillard Library at GPS 35.654362, -101.405266.
