continuing along church street north of bartow, us 221/sr 171 stays relatively north as it curves back and forth through western jefferson county, passing through a few agricultural areas, and residential zones, as well as the occasional church, but mainly forestland with some wetlands hidden in the tress. the one exception to this is a dip in the road approaching a culvert over a small river leading to cobb lake. near almira the road seems as if it's about to end at a west to east road surrounded by more farmland, but instead turns right and joins a concurrency with georgia state route 24. from that point on, us 221/srs 24/171 curves to the east-northeast as they approach a bridge over the ogeechee river, and the forested marshland that surround the river. the concurrency with sr 171 finally ends at grange road, which runs northwest, but us 221/sr 24 crosses another bridge over a tributary to the ogeechee river before entering louisville. at west broad street, us business route 1/sr bus 4 joins the routes from the south, and the concurrency with sr 24 ends as it briefly turns south onto ninth street. us bus 1/221/sbr 4 curves to the north in front of city hall, then later joins up with and at-grade interchange with us 1 and srs 4/17 as the business routes for each come to an end. from that interchange on, us 1/221/srs 4/17 is a two lane highway with continuous left-turn lane provisions that end at the driveway to the jefferson county landfill. that center turn lane is replaced by a brief second northbound lane. long after that second northbound lane replaces the first one, the routes encounter the southern terminus of georgia state route 296, then passes along the eastern edge of jefferson county high school (sr 296 runs west of the western edge of the school). running through wrens, the proposed interstate 14 is supposed to run through and have an interchange with us 1-221, but for now the segment of that proposed interstate serves as the southern end of the sr 88 multiplex. northeast of there, us 1/221/srs 4/88 loses the concurrency with sr 17 at thompson street, and sr 88 leaves the concurrency at sr 80 as it briefly joins that route in another concurrency. just after us 1/sr 4 widens to a four-lane undivided highway, us 221 splits off to the northwest cosigned with georgia state route 47 and passes the wrens memorial airport. later us 221/sr 47 starts to curve more toward the northeast rather than the northwest.
