I-126 was six-laned from I-26 to Greystone Blvd and 8 laned from Greystone Blvd to Huger St in 1978.
One exit was not part of the original lineup: S-40-2963 Colonial Life Blvd (btw 1986-90)
Comment: I-126 provides freeway access to Riverbanks Zoo and Downtown Columbia from I-26.
For many years I-126 was not identified from I-26 EB, only US 76 was on the BGS's. The opposite was true on I-26 WB - I-126 shield but no US 76 shield. In the 2000s, this changed to where a text ROUTE I-126 is now on I-26 EB signs and no indication US 76 goes with it.
