In South Carolina, I-85 bypasses Clemson and Anderson on the way to Greenville. Beginning at Anderson, I-85 widens from four to six lanes. Near Powdersville, US 29 joins I-85 and they run concurrently until they cross the Saluda River.

History

In the northern half of I-85, the route roughly parallels an ancient Indian trading path documented since colonial times from Petersburg, Virginia, to the Catawba Indian territory. I-85 near Petersburg once formed the southern end of the Richmond–Petersburg Turnpike, which was completed in 1958. The tolls were removed in 1992 after I-295 was completed. Before a 2010 decision to raise the speed limit in the state to , Virginia's portion of I-85 was also the only Interstate Highway in the state with a posted
speed limit Speed limits on road traffic, as used in most countries, set the legal maximum speed at which vehicles may travel on a given stretch of road. Speed limits are generally indicated on a traffic sign reflecting the maximum permitted speed - expre ...
greater than . It was raised from on July 1, 2006, by the state legislature. In 2004, I-85 was rerouted around Greensboro; and it split with I-40 east of the original departure point. I-40 ran with I-85 along the bypass to the southern/western end and I-40 continued on a new freeway alignment at exit 121 until September 2008, when it was rerouted back to its old alignment through the city. Despite its reroute around Greensboro, the overall length for I-85 in North Carolina remains the same as before. On the evening of March 30, 2017 a massive fire collapsed a bridge on I-85 in Atlanta. As a result, I-85 was closed to traffic for approximately between its split with I-75 and the interchange with SR 400.
