This is a Historic Resources Survey Along Luxapalilla Creek and includes references to Bluett's Bridge, as well as a map on page 34 showing its location.
Hope this helps.
BTW, from age 4-12, my family and I lived in West Point, MS, just a short distance from Columbus. I noticed the reference to "Probst Park" (Propst Park) in an earlier posting which peaked my interest, as I visited and picnicked at this park as a child.
