State Route 32 (SR 32), also known as the James A. Rhodes Appalachian Highway, is a major east–west highway across the southern portion of the U.S. state of Ohio. It is the eighth longest state route in Ohio, spanning southern Ohio from Cincinnati to Belpre, across the Ohio River from Parkersburg, West Virginia. Except in Belpre, leading up to the bridge into West Virginia, the entire route outside Cincinnati's beltway (Interstate 275, I-275) is a high-speed four-lane divided highway, forming the Ohio portion of Corridor D of the Appalachian Development Highway System. Route description SR 32 begins at a junction with Columbia Parkway (U.S. Route 50, US 50) in eastern Cincinnati, near the border between the neighborhoods of Linwood, Mount Lookout, and Columbia-Tusculum, in the area of Lunken Field. It follows Beechmont Avenue, running concurrently with SR 125, until it crosses the Little Miami River, where it turns north on Batavia Road and continues past Newtown. At the Clermont County line, the road becomes the Appalachian Highway, a four-lane, limited-access divided highway that is part of Corridor D. Between I-275 and Mount Orab, the highway alternates between at-grade and grade-separated interchanges. In Pike County, it runs concurrently with SR 772, then with SR 124. Next, it intersects the ramps to US 23 in Piketon. There is an unusual interchange configuration near Jackson at US 35, which is an expressway in both directions. Each highway has ramps that exit to the other highway, with right-turning traffic merging onto the second highway, but left-turning traffic coming to an at-grade intersection. Both highways end up having at-grade intersections, albeit with a 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. SR 124 departs at Roads. US 50 rejoins SR 32 in front of the Gordon K. Bush Airport in Albany. The two routes briefly run concurrently with US 33 in Athens. Near Coolville, SR 7 joins from the south. Just before Belpre, US 50 and Corridor D turn south, crossing the Ohio River on the Blennerhassett Island Bridge toward Parkersburg, West Virginia. SR 32 and the Appalachian Highway continue eastward through Belpre. The Appalachian Highway ends just west of the Ohio River; SR 7 turns north, remaining a
