Interstate Business Route 26

Interstate 26 has no business loops or spurs, but two of its "children" routes, Interstates 126 and 526, have business spurs associated with them. SCDOT utilizes Spur and Connector routes as part of its U.S. and State Highway inventory. These are seldomly signed. Five Business Spurs are included in the system as well, though only two are signed (the east ends of I-20 and I-526). All five otherwise consist of arterial or surface street extensions of freeway ends. These include the north end of I-385, the south end of I-585 and the east end of I-126.

Interstate Business Route 126

Location Status Description
Columbia Active Business Spur I-126 follows Elmwood Avenue east from I-126 at the Huger Street tri-level interchange to South Carolina 277 (Bull Street) in Columbia. Elmwood Avenue doubles as U.S. 21, 76, 176, and 321 along the five block stretch east of the freeway end as well. A lone span-wire supported guide sign references the boulevard as Business Spur 126 (as of 2011), and it hangs above the westbound lanes preceding Main Street.

Although there are shields for Business Spur I-126, it may not have been the intended designation for Elmwood Avenue. Chris Martin wrote on November 4, 2000, "I just had lunch with a friend over from the SCDOT and the subject of the BS-126 controversy came up in our conversation. Apparently, it is indeed correct that there is no BS-126, not anymore, not ever. He says it does not appear on any of their planning maps from the late 1950s (when the Interstate 26 system was commissioned) onward. He is not sure whether or not it existed somewhere unofficially, however. The two BS-126 signs that still exist on overhangs between Sumter/Main and Assembly/Main are for a ghost highway!"

Interstate Business Route 526

Location Status Description
Mount Pleasant Active Business Spur I-526 is Chuck Dawley Boulevard, which connects the east end of Interstate 526 at U.S. 17 with South Carolina 703 (Coleman Boulevard). It was approved by AASHTO in 1992 to replace U.S. 17 Business along what was known as Old Georgetown Highway.
S.C. 703 east from the Arthur Ravenel, Jr. Bridge to Chuck Dawley Boulevard, and Business Spur I-526 east back to U.S. 17, follow the pre-1960s routing of both U.S. 17 & 701 through Mount Pleasant.
