 The intersection with Norristown Road is where US 221/SR 171 crosses the Treutlen-Emanuel County Line, then it crosses a bridge over the Ohoopee River as it enters Norristown.Here the closest resemblance to a major intersection is Keas Old Mill Pond Road and Norristown Covena Road.North of Norristown, the road curves to the north-northeast and remains within that trajectory, even as it passes through the blinker-light intersection with U.S. Route 80.
