Spartanburg

The lone business loop in South Carolina is an eight mile long freeway running between I-85 and the city of Spartanburg. The limited access road serves the Spartanburg County communities of Fairforest, Johnson City, Lone Oak and the University of South Carolina Upstate.

Interstate 85 through the Spartanburg area was constructed in the 1950s as a bypass route for U.S. 29. Traffic growth along the substandard freeway through the 1970s and 80s overwhelmed the route, resulting in plans to either widen it or replace it with a new alignment to the north. Ultimately a new route for I-85 was chosen in 1986 as it would minimally disrupt existing traffic patterns and not involve costly upgrades to the old route.

Work broke ground in 1988 on the new six lane alignment, with completion in early October 1995. As approved by the American Association of State Highway and Transportation Officials (AASHTO) on April 2, 1995, when the new route opened, old I-85 was redesignated as Business Loop I-85.

Traffic counts dropped significantly along the former route, leading to a decline in revenue at several area hotels. Mike Whitt, a representative of the Spartanburg Hospitality Association (SHA), gave a presentation to the Spartanburg Area Transportation Study (SPATS) committee on March 31, 2000 asking for support in an effort to redesignate Business Loop I-85 as Interstate 685. The philosophy was that an Interstate designation would bring back some of the travelers now bypassing the area on I-85. The committee responded with concerns that the existing freeway would not meet interstate standards and that upgrades needed were too costly.¹

A follow up by Mike Whitt on December 14, 2000 revealed that the South Carolina Department of Transportation (SCDOT) required $150 million in construction to modernize the business loop freeway. Additionally, the community was generally apathetic and non-supportive about the issue. SCDOT offered instead to place overlays displaying “Freeway Loop” on guide signs for Exits 69 and 77 on I-85.

Subsequent attempts by the SHA were planned in 2001 and 2002 to convince area residents that the Spartanburg was losing out on opportunities to bring in added revenue from motorists bypassing along Interstate 85.

Business Loop I-85 superseded U.S. 29/70 along the Temporary section of I-85 through Lexington, Thomasville and High Point. Portions of the route included 1950s era expressways built to join the three cities with Greensboro to the northeast. This section traveled 30.8 miles from a wye interchange (Exit 87) in southwest Lexington to a trumpet interchange (Exit 118) on the outskirts of Greensboro. U.S. 29/70 overlapped with the entire route, while the southern four miles coincided with U.S. 52 and Interstate 285.

With the completion of the Interstate 85 bypass around Greensboro (Painter Boulevard) on February 22, 2004, Business Loop I-85 was extended northward over the former I-85 route through the city. This included an implied overlap with I-85 between Exits 118 and 120 A extended the Business Loop mileage, and exit number sequence, through Greensboro to the exchange with I-40 south of Downtown.

Interstate 40 and Business Loop I-85 combined for eight miles east to I-85 at Exit 131 and I-785/840 on the east side of Greensboro.

Completion of the southwest leg of Painter Boulevard on February 21, 2008 shifted I-40 to bypass the city to the south, partially alongside I-85. This coincided with the redesignation of the original Interstate 40 across Greensboro as new Business Loop for I-40. The sign changes lasted just seven months before I-40 was returned northward.

The new alignment of Interstate 85 around Greensboro was approved by AASHTO on May 14, 2004. The old alignment of Interstate 85 was approved as an extension of Business Loop I-85 at the same meeting. Guide sign changes following the completion of Interstate 840 (Greensboro Urban Loop) in 2023 remove all references of the business route in Greensboro. Sign changes further south also drop Business Loop I-85.

Greenville, South Carolina

SCDOT actively inventories Spurs and Connector routes in their U.S. and State Highway systems. Four of the S.C. Interstates were given Spurs as well, including the north end of Interstate 385 outside Downtown Greenville. Business Spur I-385, an unsigned route as of 2004, extends west from the freeway end of I-385, 0.49 miles to U.S. 29 (Church Street) in the Greenville central business district. The route was signed along U.S. 276 (Stone Avenue / Laurens Road) at the diamond interchange with I-385 south and Business Spur I-385 north until Fall 2003, when construction to expand I-385 rebuilt that exit. When work was completed in 2004, signs for the business spur were not replaced.

Business Spur I-585 overlays U.S. 176/S.C. 9 along Pine Street south from the I-585 freeway end to Garner Road. The route consisted of one sign, which erroneously references Pine Street north of Garner Road as the mainline of Interstate 585.

Until 2001, a tri-color Business Spur I-585 shield was posted at Main Street (old U.S. 29) and U.S. 176/S.C. 9 (Pine Street) east of Downtown Spartanburg. North of that intersection, a trailblazer for I-585 stands along Pine Street, leaving no other references to the business spur in place.
