 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).
