Interstate585 (I-585) is a 2.25-mile-long (3.62km) auxiliary Interstate Highway of I-85 in the US state of South Carolina. It has been an orphan auxiliary route to I-85 since 1995 when the Interstate was relocated further north bypassing Spartanburg. In a complete concurrency with US Highway176 (US176), it spurs south from I-85 Business (I-85 Bus) for a few miles before entering Spartanburg.
Route description
I-585 is cosigned the entire length with US176 and uses US176's exit number system instead of its own. The route is also signed as North Pine Street its entire length. The southern terminus begins at exit25, where the road continues as US176/South Carolina Highway 9 (SC9). I-585 remains concurrent with US176 starting at exit25 as it heads northwest. It then comes across a partial interchange with California Avenue at exit24. Before exit23, there are two at-grade auxiliary lanes, one on each side which connects Milliken Road on the north side and Graham Road on the south side to the highway. At exit23, the highway comes across I-85 Bus, forming a parclo interchange, ending just north of it. US176 continues west to I-85.
History
From the highway's initial designation in 1962 until 1995, I-85 followed what is now designated I-85 Bus. In that year, I-85 moved to the north, orphaning I-585 from a direct connection to its parent route, a situation that remained until upgrades to US176 over the next decade provided a freeway connection between I-85 and I-85 Bus, except for a stoplight at Upper Valley Falls Rd/Fairforest Rd. Additionally, US176 is connected to I-85 with a stoplight-controlled diamond interchange instead of a freeway-to-freeway interchange. The upgraded segment is cosigned with I-585, although it is not officially part of that route.
Exit list
Exit numbers, where present, are based on US176 mileage. The entire route is in Spartanburg County.
