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

Route description[edit]

I-585 is co-signed the entire length with U.S. Route 176 (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.[3]

History[edit]

The location of I-585 was planned as I-26 in this 1955 map. The connection along US 221 was never built.

This highway was once connected to I-85 from opening until 1995; that year, I-85 was moved north to bypass Spartanburg, leaving I-585 as 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.[4] The ramps from I-585 southbound to I-85 Bus. north and south opened on October 9, 2006; subsequent ramps between the two roads have since been reopened including a large fly-over ramp that overpasses the East Campus Boulevard exit.[citation needed]

Currently, US 176 remains a freeway north of the I-85 Bus. interchange until a traffic signal with Upper Valley Falls Road, prior the interchange with I-85. Some vehicles on US 176 must cross oncoming traffic in order to access a some directions of I-85 as it is a typical diamond interchange.

Exit list[edit]

Exit numbers are based on US 176 mileage. The entire route is in Spartanburg County.
