Route description
I-126 begins in northwestern Columbia at an interchange with parent route I-26 and US 76 along the Saluda River. The terminus is located near the Dutch Square shopping center and I-26's own interchange with I-20, nicknamed "Malfunction Junction", which includes a weaving ramp from I-126's westbound lanes to I-20. The eight-lane freeway travels southeast along the Saluda River and passes the Riverbanks Zoo at Greystone Boulevard. It then crosses over the Broad River on the Timmerman Bridge near the mouth of the Saluda River. I-126 enters Downtown Columbia and reaches its easternmost interchange with Huger Street, which carries US 21, US 176, and US 321. The freeway continues east for several blocks on Elmwood Avenue, which carries the highways that Huger Street did, and ends at Gadsden Street near the South Carolina Governor's Mansion.

Why this record matters
The phrase “auxiliary Interstate Highway in Richland County, South Carolina, United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
