Route description
All of SR 785 is situated within the rural Jackson Township in southern Highland County. The state highway is not included within the National Highway System.

SR 785 begins at the intersection of SR 247 and Fair Ridge Road (County Road 3). Heading southeast from there, the route passes a few homes and into a patch of woods. The highway turns east at Greenbriar Road, then bends to the northeast, and then more east-northeasterly as it emerges from the forest and into a landscape dominated by open farmland. After passing the Young Road intersection, SR 785 goes amid a small patch of woods, then re-emerges into open farmland as it curves to the east. Just after Locust Road, the highway bends to the northeast, nudging some patches of trees alongside the roadway to the southeast. SR 785 intersects Storer Lane, then follows an S-curve going east-northeast and back to the northeast. The highway enters into a residential area just prior to where it meets SR 73, which marks its endpoint.

History
SR 785 was designated in 1937 along the routing between SR 247 and SR 73 southeast of Hillsboro that is maintains to this day. The highway has not experienced any significant changes to its routing since it was established.
