 SR 57 joins US 220 south for a short concurrency before splitting from US 220 at a partial interchange that only allows access to SR 57's new road, two-lane Appalachian Drive, from the north.SR 57 parallels the Smith River and the rail line again past Fieldale, where the highway crosses to the south side of the track.Just after passing the WHEE radio tower, the state highway enters the city of Martinsville, its name changes to Fayette Street, and the road curves northeast under the railroad track toward downtown.
