US 220-Y: Appeared Sept 1940 when US 220 was rerouted from Martinsville to Bassett Forks via Collinsville. The Bassett Forks area had VA 57-Y and US 220-Y connectors.
While VA 57 and 57-Y had adjustments, it appears Us 220-Y stayed essentially the same.
In Jan 1978 (CTB), US 220-Y was destroyed by the construction of the current US 220-220 Business interchange.
