the edge of Jackson. The route then reaches a grade-separated, right-in/right-out interchange; westbound there is a right-in/right-out at Keystone Furnace Road; eastbound there is a right-in/right-out at McCarty Lane; these roads are connected via Industry Drive and Acy Avenue, which overpasses US 35. Next, there is an unusual interchange configuration at SR 32/SR 124, which is an expressway in both directions. Each highway has ramps that exit to the other highway, with traffic merging onto the second highway, but traffic coming to an intersection. Both highways end up having intersections, albeit with grade separation of the main highway corridors. This interchange type is sometimes termed a "windmill" interchange, but it is not related to the interchange type of the same name. This junction is the only interchange of its type known to exist in the world. Soon after passing the last interchange and still skirting Jackson, the highway once again becomes a freeway and has an interchange at Pattonsville Road/Broadway Street. Turning briefly north, then northwest, the route leaves Jackson and reaches an interchange with SR 93. It next has an interchange with Jackson County Road 84 (Chillicothe Pike). After the last interchange, the highway becomes an at-grade expressway for about . Along this section, there is a rest area next to the westbound lanes but accessible from both directions, with additional access via Cain Road (Jackson Township Road 213). US 35 then turns roughly west, entering Ross County and reaching an interchange with Vigo Road/Watson Road at Richmond Dale. At this point the route again becomes a freeway. Turning north and northwest, the section between Richmond Dale and Chillicothe includes a large cut through a ridge and provides westbound motorists with a panoramic view of the Scioto River valley. Southeast of Chillicothe, westbound US 50 joins US 35 in a concurrency at a hybrid interchange; similar to a diamond interchange, the exit ramp from US 35 east carrying US 50 east becomes a two-way road, curves around and crosses over US 35 about east; the other ramps connect to this overpass. Next, US 50 west leaves the concurrency at a partial interchange at Eastern Avenue; there is only a westbound exit and an eastbound entrance. Then, the US 23 north freeway joins US 35 in a concurrency at a partial-Y interchange; there is an eastbound exit and a westbound left entrance. Turning north-northwest, US 35 skirts Chillicothe to the
