The freeway portion ends at US 221, but the reassurance signage for I-585 continues southeast of the the Spartanburg Regional Medical Center to Linder Street. There are no end or begin markers, but signage south of Linder Street shows only US 176 and SC 9. South Carolina is retaining the 585 designation, and will in fact improve the segment of US 176 leading north from BL 85 to the new I-85. Personal e-mail, June 9, 2000.
