After cresting the Blue Ridge, US 33 enters Greene County and has a more gentle descent of the eastern side of the mountain, where the highway follows Swift Run to the hamlet of Lydia, then passes around the north side of Powell Mountain and meets the stream again west of Stanardsville, where the road expands to a four-lane divided highway. US 33 Business (Spotswood Trail) splits to the north to pass through the center of Stanardsville, the county seat of Greene County, while US 33 follows the Stanardsville Bypass. US 33 Business provides access to SR 230, which heads toward Madison. US 33 continues southeast through Quinque and intersects US 29 (Seminole Trail) in Ruckersville.
