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. north of us 80, us 221/sr 171 makes an almost immediate northwest curve at a fork in the road with cow ford bridge road, and doesn't curve back to the northeast again until after the intersection with foskey road. the road quickly enters and leaves the emanuel-johnson county line, and has one last intersection in emanuel county, specifically with wes lawson road, only to re-enter johnson county again. throughout most of the county, the road is named montgomery street. briefly, it almost seems like it's going to run straight north, but then curves to the north-northwest. the first and only major community it enters within the county is kite where it has a blinker-light intersection with georgia state route 57. beyond sr 57 it remains in a relative northwest trajectory, until it makes a sudden curve to the right near the intersection of gumlog road to cross a bridge over the little ohoopee river, and then curves back to the left again after the intersection with swan creek road.
