Interstate 585 (I-585) is a spur route of Interstate 85, which connects Spartanburg, South Carolina in the United States.

Route description

I-585 is co-signed the entire length with US 176 and it uses US 176's exit number system instead of its own. Between exits 23 (I-85 Business) and 25B (US 221) the road is a freeway but has substandard or no shoulders. To the south of exit 25B, US 176 becomes boulevard grade, where I-585 ends.

History

This highway was once connected to Interstate 85 from opening until 1995; that year, I-85 was moved north to bypass Spartanburg, leaving I-585 an orphan, segregated from the rest of the Interstate Highway system. There is a project underway to extend I-585 along US 176 to I-85's new location. The ramps from I-585 Southbound to Business Loop 85 North and South opened on October 9, 2006. The Ramp from I-585 Northbound to Business Loop 85 Northbound is open and the Southbound Business Loop 85 entrance is open. The ramp from Business Loop 85 Southbound to I-585 Northbound is open (it is now a large fly-over ramp that overpasses the East Campus Boulevard exit), and the ramp from Business Loop 85 Southbound to I-585 Southbound has been re-opened as well.
